My personal favourites are: Object Oriented Design and Analysis by Grady Booch This is a very 'from the ground up' approach top OOP by one of the founding fathers based around C++ examples and using the authors own design notation. There are rumours of a new version based on Java and UML so borrow rather than buy is my recommendation for now! OO Software Construction by Bertrand Meyer Same basic approach but much more detailed. This is the most complete and scholarly coverage of OOP around. Unfortunately it uses Eiffel, a great language but hardly anyone uses it! Object Oriented Programming by Timothy Budd This one is for the hands-on types, teaches OO using several languages with lots opf comparitive examples. Its much shorter than the others with less talk about design and more about code level issues. > Before the Martin book came out my favorite was "Design Patterns: Elements > of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph > Johnson and John M. Vlissides. A good one, but not for the faint hearted. Its quite ponderous in style (IMHO!) and delves into some quite deep and subtly design concepts, but definitely one to keep with you long after you've finished with the others.

Suppose that I need to use in my project a module that belongs to another project, because - with some tuning - it can fit my needings. This is what I mean, with an example: module.py limit = 30 class A: def __init__(self): self.num = 20 def info(self): return limit def inc_num(self): self.num += 1 def check(self): return self.num > limit Now suppose that I'd like to have the same class A in my module, but also I want that the initial value of limit is set to 25. >>> limit = 25 >>> from module import A >>> a = A() >>> a.info() 30 Now I have a couple of questions. The most important: how to reuse the class A in my module? "class A" is not short and I think that copy/paste, then apply changes, wouldn't be a valid solution! This is the second question, more for curiosity than for real necessity, anyway: Considering that: >>> limit # Obvious 25 >>> print a.limit # Obvious Traceback (most recent call last): File "", line 1, in ? AttributeError: A instance has no attribute 'limit' >>> print A.limit # Obvious Traceback (most recent call last): File "", line 1, in ? AttributeError: class A has no attribute 'limit' where is the value 30 coming from? Thanks, dear tutors!

The problem is that class A is seeing the limit defined in it's module. 'global' variables in Python actually have module scope, there is no truly global scope in Python (OK, there's the __builtin__ scope, but this is a beginner's list!) IMO the best solution is to pass limit as a parameter to A's constructor and save it as an instance attribute: class A: def __init__(self, limit): self.limit = limit self.num = 20 def info(self): return self.limit def inc_num(self): self.num += 1 def check(self): return self.num > self.limit Now you can create whatever kind of A's you want: from module import A a = A(30) etc. Another way to do this is to make limit a class attribute. Then you can change it in subclasses: class A: limit = 25 def __init__(self): self.num = 20 def info(self): return self.limit def inc_num(self): self.num += 1 def check(self): return self.num > self.limit class B(A): limit = 30 a = A() a.info() --> 25 b = B() b.info() --> 30 Kent Note you still refer to self.limit so the value of limit in the current class will be found. > where is the value 30 coming from? from module.limit.

Then you can change it in subclasses: Idem [cut] A way I found is to import module directly and then simply assign to it the property limit: >>> import module >>> module.limit = 25 >>> a = module.A() >>> b = module.A() (25, 25) This however has a side effect (that luckily is not a big problem, because I don't need to change limit after the first time): >>> module.limit = 26 >>> a.info(), b.info() (26, 26) > > where is the value 30 coming from? > > from module.limit. I have some difficulties understanding this. In my previous post the syntax is: from module import A and so 'module' is not imported.

A minor rewrite now will save you trouble later. If you want to be backwards compatible you can give a default value for limit: class A: def __init__(self, limit=25): # etc then you can say a = A() a.info() --> 25 b = A(30) b.info() --> 30 a.info() --> still 25 > A way I found is to import module directly and then simply assign to > it the property limit: > >>>>import module >>>>module.limit = 25 >>>>a = module.A() >>>>b = module.A() > > (25, 25) > > This however has a side effect (that luckily is not a big problem, > because I don't need to change limit after the first time): > >>>>module.limit = 26 >>>>a.info(), b.info() > > (26, 26) Yes, you can do that but it's ugly and fragile. It will cause obscure bugs the first time you write a program that uses module twice with two different limits. Maybe you will never do that.

In my previous post the > syntax is: from module import A and so 'module' is not imported. Right, but all access to limit is from inside module. Names are looked up first in the local namespace (the current function), then in any enclosing name space (if you have nested functions), then in the namespace of the *containing* module (*not* the module where the function is used, rather the module where it is defined) and finally in the built-in namespace. Again, 'global' scope is the scope of the textually containing module, not the scope of the calling module. This is called static or lexical scoping.

If you want to avoid COM, why don't you use it to save each page of the spreadsheet as a CSV file and then go from there? The close tie-in between Excel and COM is designed for your problem... Alternatively check PyPI, I'm sure there's something that will do what you want, but most of what you find will probably just use the Win32 package instead of reinventing the wheel.

I know it needs improvements, and I've noted them below: Hi Nathan, Yes, some of it should be usable if it were in a GUI. The easy way to pick out what functions will and won't be useful is this: what functions use print and input statements? If you exclude those, then what's left will be useful for both your GUI and terminal programs. Actually, that's not quite accurate. For functions that do use print statements, it's possible to split off the console-driven stuff from the pure computation stuff, so there's actualy quite a bit you can reuse. Let's go into this. load_file() and safe_file() are directly reusable, since they don't interact with the user. Let's look at something that mixes computation with user interaction: > def add_site(): > print "Add a login info card" > site = raw_input("Site: ") > ID = raw_input("User ID and passcard, seperated by a space: ") > sitelist[site] = ID It's possible to break this down into two parts: the part that asks for login info: ###### def ask_for_login_info(): print "Add a login info card" site = raw_input("Site: ") ID = raw_input("User ID and passcard, seperated by a space: ") return (site, ID) ###### and the part that really does the gruntwork of entering into the site list: ###### def add_to_sitelist(site, ID): sitelist[site] = ID ###### Because this example is so small, doing the breakup this way is a bit silly, so maybe this is overkill for your program. But, in general, when we design a program to be used from both the console and the GUI, we'd break out the direct user interface stuff into a separate set of "user interface" functions, and have those interface functions reuse the common "model" functions that do the underlying work. In a GUI framework like Tkinter, the ask_for_login_info() function might use a "dialog box". http://www.pythonware.com/library/tkinter/introduction/dialog-windows.htm On a first pass to GUI-ify your program, each 'print' statement could be replaced with something like a printDialogMessage(): ###### import tkSimpleDialog import Tkinter def printDialogMessage(root, msg): """Uses a dialog window to display a message. If ok is pressed, returns True. If cancel is pressed, returns False. """ class Dialog(tkSimpleDialog.Dialog): def body(self, master): Tkinter.Label(master, text=msg).pack() def apply(self): self.result = True d = Dialog(root) if d.result: return True return False ###### Similarly, we can write something (let's call it readDialogInput) that simulates the console raw_input() function. And if you replace each use of 'print' with 'printDialogBox' and 'raw_input' with 'readDialogInput', we could argue that we have a GUI program. But if we take this route and just stop here, then this is no better than the console program. Getting GUIs right is more than just taking existing programs and putting nice shiny windows on them: it involves good user interface design that takes advantage of the things that GUIs get right. I don't know if there's a quick-and-dirty way to design such GUIs, though. You might find: http://www.manning.com/books/grayson helpful in getting started with Tkinter programming. Hope this helps!

If anyone has any pointers I would be much appreciated. Hi Erik, Do you know what a shell is? I think KDE calls it "Konsole". If you start up a shell and then type "python", you will start up the python interpreter and be able to interact with it. This is quite handy! If you haven't already done so, check out the tutorial on python.org. It talks about this (amongst other things). As to what app to code in ... that's a can of worms :-) I am a fan of emacs and vi. You could also try IDLE, which comes with python. -- John.

After you feel more comfortable with your environment, then go for Python. Trying to learn both at the same time might be counterproductive, especially in the presense of mistakes. If things go wrong, you'll want to know if you're looking at a Unix error or a Python one. You can find KDE user documentation here: http://docs.kde.org/ http://docs.kde.org/development/en/kdebase/userguide/index.html When you feel comfortable enough with your environment, then you can find good starting points for learning Python here: http://wiki.python.org/moin/BeginnersGuide > > What apps to code in, is there an interactive mode? Yes, Python has an interactive prompt. If you do have a console handy, type 'python' and see if something comes up. Best of wishes to you!

The inventory list can be just for a in self.inventory: print a.name You can access object attributes from outside the object, they are public. > didn't know we had new-style classes. Yes, modern practice is to have your classes inherit from object, e.g. class Room(object): >>> def move(self,direction): >>> if self.location.exits.has_key(direction): >>> self.location = self.location.exits[direction] >>> print self.location.name >>> else: print 'alas, you cannot go that way' >>> def dig(self,direction): >>> lcoords = list(self.location.coords) >> >>Why do you convert to a list?

Yes, I understand the intent, but I think you can use self.location.coords everywhere you are now using lcoords - the conversion to list is not needed. >>but I think I would make ncoords a local variable and just say >> ncoords = (0, lcoords[1] + 1) >> >>With ncoords as a global you have a bug, you only set one element here, >>the other one will be left over from the last time through. > > i stuck that global up there to make something work. i forget what now. > maybe i should take notes or something :) i'm thinking i should write some > separate convert directions to coordinates function. That sounds like a good idea. But still you can create ncoords directly as shown above.

I don't know how you can get such a stack trace. Maybe try deleting all the .pyc files to make sure they are in sync with the source and try again? The actual error indicates that the input data is not valid utf-8. Are you sure that is the correct encoding for the input file? If the file is utf-8 and has bad characters you could pass error='ignore' or error='replace' as a parameter to codecs.open() to change the error handling style to something more forgiving. > > and > > Traceback (most recent call last): > File > "C:\Python23\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", > line 310, in RunScript > exec codeObject in __main__.__dict__ > File "C:\Python\BA\Oversett.py", line 49, in ? > File "C:\Python\BA\Oversett.py", line 33, in kjor > if t % 1000 == 0: > UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 17: > ordinal not in range(128) Again this stack trace doesn't make sense, the indicated line doesn't do any string operation. This error message normally occurs when a non-ascii string is converted to unicode using the default encoding (which is 'ascii'). Often the conversion is implicit in some other operation but I don't see any such operation here. > > objSelection.Find.Execute() is supposed to accept any kind of string. (It > is the function Search & Replace in MS Word). It has to make some assumption about the type of the string. Does it want unicode or encoded bytes? If encoded bytes, what encoding does it expect?

(Python 2.3 IDLE GUI in WindowsXP Home edition) Thank you and the others who have sent replies! Attached to this file is a Rich Text File using "Save Copy As" from the Python Shell display. This will give an example of the desired formatted output. Some displayed lines are long, so I use legal size paper and landscape mode for printing this RTF file. Methods for turning on true division? A. Install the new Python, when it is available. When will this be available? B. from__future__import division This will work properly in an IDLE Python Shell, if I type it in, but not when it is present in .py modules. I see that it was read from the .py file by the python shell, but the behaviour in the shell still is not changed from integer division to normal division. (I put the statement at the beginning of my .py modules.) C. -Qnew I did not understand how to get and install Qnew, so I searched on the information below, and got a lot of results (1100), that confused me further. D. customized parser and evaluator This approach might be the best, but before I consider it, I must get the two affected fuunctions working. I saved the function modules that you refactored for me, into separate files, but should probably put them all into one file later. 1. Extract Equation 2. EvaluateEquation 3. PrintEquationAndValue 4. DisplayPyFile and my 5. Calling Program Module When I ran the caling module, (and got the indentation right in the function modues) all modules appeared to work except for the PrintEquationAnd Value Function which gives a syntax error for "if value:" with an arrow pointing to value. Reproduced below are the four function modules. and the calling module, and included is the original display module. # printEquation.py ############################################ def PrintEquationAndValue(equation, value): """Prints out the equation and its value.""" if value: name, assignment, comment = equation print "%10s = %18.15e (%s)\t[%s]" % (name, value, assignment, comment) else: print "%s not defined. %s" % (name, assignment) ############################################ # extractEquaiton.py def ExtractEquation(line): """Either returns a 3-tuple (name, assignment, comment) from the line, or None if we can't extract a definition from the line.""" line = line.strip() if not line: return None leftAndRight = line.split('#',2) comment = '' if len(leftAndRight) > 1: comment = leftAndRight[1] assignment = leftAndRight[0] leftAndRight = assignment.split('=') if len(leftAndRight) == 2: name = leftAndRight[0].strip() return (name, assignment, comment) return None # evaluateEquation.py # ############################################## def EvaluateEquation(equation, context): """Evaluates the equation in a given context.

The easiest is to start Python up with the '-Qnew' command line option, which turns on true division globally: mumak:~ dyoo$ python -Qnew Python 2.3.5 (#1, Mar 20 2005, 20:38:20) [GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin Type "help", "copyright", "credits" or "license" for more information > I'd recommend this approach: it means you won't have to change much. Unfortunately, this means that you'll have to remember to use '-Qnew' all the time, and that's bug-prone. An alternative way is to fix the bug is to modify extractEquation and evaluateEquation so that it doesn't depend on Python's evaluation functions. To an experienced programmer, I'd recommend that approach, to replace the call to 'exec' with a customized parser and evaluator: we have more control over the arithmetic. If you really need something like this, one of us can probably cook up such an evaluator for you. --------------------------------------------------------------------------------------------------- Thank you for your help!

If encoded bytes, what encoding does it expect? I think the letters should be accepted. The pythonscript here is written to replace abot 25000 MS Word-macros, so all the letters have been accepted by MS Word when feeded by Visual Basic. All I have done now is to extract the words from the macros and put them in a file. -- This email has been scanned for viruses & spam by Decna as - www.decna.no Denne e-posten er sjekket for virus & spam av Decna as - www.decna.no From kent37 at tds.net Wed Nov 30 19:41:54 2005 From: kent37 at tds.net (Kent Johnson) Date: Wed, 30 Nov 2005 13:41:54 -0500 Subject: [Tutor] Unicode trouble In-Reply-To: <1789.193.71.156.231.1133374454.squirrel@mail.sporck.net> References: <1789.193.71.156.231.1133374454.squirrel@mail.sporck.net> Message-ID: <438DF272.2060400@tds.net> ?yvind wrote: > ?yvind wrote: > >>>Where are you getting these errors (what line of the program)?

Not that exotic, no, but they have different representations in latin-1 and utf-8, and maybe other latin-x as well.

Since I tell the > program to change to utf-8, not only once but twice? if the stack trace made sense I would have a better answer for you. >>>objSelection.Find.Execute() is supposed to accept any kind of string. (It >>>is the function Search & Replace in MS Word). I doubt it. This function has no way to distinguish utf-8 from latin-1 or latin-2 or ebcdic or whatever. If you are giving it encoded strings, it has to make some assumption about the encoding. Or else it is expecting unicode strings. If this is the first time you have had to deal with different encodings you might want to read http://www.joelonsoftware.com/articles/Unicode.html or any of the other articles referenced at the end of this essay: http://www.pycs.net/users/0000323/stories/14.html Kent -- http://www.kentsjohnson.com From klappnase at freenet.de Wed Nov 30 20:46:30 2005 From: klappnase at freenet.de (Michael Lange) Date: Wed, 30 Nov 2005 20:46:30 +0100 Subject: [Tutor] Unicode trouble In-Reply-To: <438DF272.2060400@tds.net> References: <1789.193.71.156.231.1133374454.squirrel@mail.sporck.net> <438DF272.2060400@tds.net> Message-ID: <20051130204630.2ca9aba8.klappnase@freenet.de> On Wed, 30 Nov 2005 13:41:54 -0500 Kent Johnson wrote: > >>>This is the full error: > >>>Traceback (most recent call last): > >>> File > >>>"C:\Python23\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", > >>>line 310, in RunScript > >>> exec codeObject in __main__.__dict__ > >>> File "C:\Python\BA\Oversett.py", line 47, in ? > >>> File "C:\Python\BA\Oversett.py", line 23, in kjor > >>> en = i.split('\t')[0] > >>> File "C:\Python23\lib\codecs.py", line 388, in readlines > >>> return self.reader.readlines(sizehint) > >>> File "C:\Python23\lib\codecs.py", line 314, in readlines > >>> return self.decode(data, self.errors)[0].splitlines(1) > >>>UnicodeDecodeError: 'utf8' codec can't decode bytes in position 168-170: > >>>invalid data > > > > > >>This is fairly strange as the line > >> en = i.split('\t')[0] > >>should not call any method in codecs.

As far as I see here, isn't the line return self.decode(data, self.errors)[0].splitlines(1) causing the traceback? I haven't read all of this thread, but maybe you are trying to pass a non-utf8 string to the utf8 codec?

Yes, I guess that much is pretty clear - there is some data in the source file that is not valid utf-8. Kent From keridee at jayco.net Wed Nov 30 23:00:09 2005 From: keridee at jayco.net (Jacob S.)
