Remember that in the floating point representation the decimal part is represented in base 2 so 2/10 is not actually possible. This is as close as it can get. The difference will be due to how str() is implemented on the two systems which is probably just done using printf("%f", ld) or similar. I'll bet that if you try: import struct struct.pack('f', (round(4,23452345, 1))) on both boxes you'll get the same thing on each. I don' t think that the docs for str() explicitly say exactly how double precision floats will be formatted so this is really neither bug nor feature just ambiguity.

Note that strictly speaking 4.2000000000000002 is the more correct answer. This may be counterintuitive since you would expect the round() function to return you a number such that the resulting number from found(4.23452345, 1) should in any case never be more than 4.2. However, if you consider that ieee 64-bit float is only capable of representing a finite set of numbers in the space of rational numbers then you would probably try to establish a rule regarding operations upon these numbers such that the result of any operation should be as accurate as possible, ie. abs(the_real_number - what number_we_can_represent) should be as small as possible. I haven't looked at any of the formal rules but I'm guessing this is one of them. (You can probably buy a giant book that describes all such rules from IEEE.) The more pertinent observation is that even when linux is printing '4.2' from round(f, 1) the answer you're getting *is* the same the only difference is the implementation of str() on each platform. This is what I was trying to point out by demonstrating that is you use struct.pack on both results you then see the same output since struct will give you the binary representation of the number. So: the answer is that if you have a float and you want to print no more then 2 decimal places you must always use %.2f. I know this is kind of a bogus answer but there you have it. You may be interested to note that if you're dealing with currencies or some such thing where fractional values beyond a certain decimal place don't make sense then you may want to use a fixed-decimal package. There's one at the Vaults of Parnassus that does this that I've used. >thanks for your answer > You're most welcome. >Ulrich Eck > >see the difference in my examples .. >WIN: > >>>>>>f = 4.23452345 >>>>>>round(f,1) >>>>>> >>>4.2000000000000002 >>> >LINUX: > >>>>>>f = 4.112345234 >>>>>>round(f,1) >>>>>> >>>4.1 >>> > >I used different random floats to test ..

Two different things here. First, getting the Print state to work in ASP is tricky, here are some hints. First, you can't use the regular print statement, and here's why. I'm not %100 sure of myself here so if anyone seems me err, please correct. The print statement sends data to sys.stdout by default. However, python in ASP caches all modules, on an application level scope, so sys.stdout is shared by every script on your website. However, in order for the webserver to know where to send data back to the client, it must have a unique filehandle (or some similar object) for each page request. Trying to set something to sys.stdout might appear to work, but actually will break as soon as you start to get simultaneous requests. (I actually had data from page 1 appears on page 2 when I requested both at the same time.) What you need to do is get some page level scope variable, stick an object in it that maps print to Response.Write, and use the augmented print. Here's what I do. from win32com.axscript.client.framework import SafeOutput _out = SafeOutput(Response) Then I use print >> _out, stuff I stuck the code in an include file that gets included on every page. Tiresome but after set up works very nicely. RA> I really want to be able to use my scripts in multiple RA> places,not just on the web server. After that you can always assign sys.stdout to _out to get the right behavior if you're not running the script from ASP. Actually I faintly remember that if _out is None, it will go to stdout too. But don't quote me. RA> If this can't be done, what variable can I examine to determine RA> where the script is being run so I know what to call? Thanks Not sure here, I suppose you could look for the existence of Response, Request, etc, ASP's built in objects to see if they are defined, but that feels icky to me. Someone must know a better way.

Or write a batch file that would cause the application to >Unload? Maybe some net service command? > I'm glad you asked! In fact there is a way to script this. IIS can be administered completely through the ADSI interface. That is to say: anything you can do with the MMC snap-in you can do through a COM interface. In fact I think there are a few things you can do only through the ADSI interface. ADSI itself is something bigger than IIS. It let's you do things to the active directory, let's you find out things about your system, and all kinds of interesting stuff. See the MSDN library for more details. More to your question at hand, I'm sure what you're looking for is a quick way to have your application unloaded since during development this is frequently necessary. The snap-in isn't that fast since the Unload button greys out after you click it so you have to cancel the property page and then re right-click on the virtual directory and select Properties. So, I wrote myself a little script. Then I decided I wanted a little gui so I could just push a button so I wrote a GUI using wxWindows. I've attached both versions. You'll see that doing this is *very* simple. Note that in my moniker 'IIS://tallan2/w3svc/1/Root/iPaymentBackend' tallan2 is my machine name, and the w3svc represents the www service and 1 is the instance. Root is just the base root for all documents and my virtual directory lives just under that. Note: I stripped out some stuff that wouldn't apply here from my GUI script and I don't have wxWindows installed at the moment because I upgraded my Python so the GUI script might not work as is. You get the idea though. -- Jens B.

I later decided that I should maybe seek out a group of more Windows-inclined people. I'm trying to implement a cross platform Windows/Unix file locking object, and right now I'm having trouble with the windows part. I was hoping to just use the msvcrt module and avoid specific use of ActiveState's win32 libraries, since I didn't want to require people to have that installed. The description of the problem follows. -- Sheila King http://www.thinkspot.net/sheila/ http://www.k12groups.org/ I'm trying to do some file locking on Windows. I'm running Win98, but I hope that the methods in the msvcrt module will work OK on any win32? I thought I understood what I was doing. I had tested a bit of file locking stuff. I opened up two separate MSDOS console windows, and tried acquiring locks and releasing locks, etc...

Indeed, the "portalocker" recipe explicitly uses overlapped IO structures. Try using LockFile - the MSDN documentation implies that it is supported on all Win32 platforms, and the error you get: pywintypes.api_error: (120, 'LockFileEx', 'This function is only valid in Win32 mode.') implies you are running on Win9x.

Yes, I am running on Win98. :A quick look at portalocker implies you will also want to drop all :references to "_overlapped" - replace them with "None". I tried that. Unfortunately, "None" didn't work. It gave me an error message asking for an integer. I spent a bit of time trying a few different things, and looking at the msdn site (here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/hh/winbase/filesio_8l6b.asp and eventually I came up with this code: filename = r'e:\apache\cgi-bin\pylinks\datalog.txt' import win32con import win32file import pywintypes from time import strftime, localtime, time f = open(filename, 'a+') fd = win32file._get_osfhandle(f.fileno()) win32file.LockFile(fd, win32con.LOCKFILE_EXCLUSIVE_LOCK, 0, 0xffff0000,0) timestamp = strftime("%m/%d/%Y %H:%M:%S\n", localtime(time())) f.write(timestamp) win32file.UnlockFile(fd, 0, 0, 0xffff0000,0) f.close() And the only error I'm getting now is: Traceback (most recent call last): File "E:\programs\LearningPython\fileIO\win32LockFile.py", line 13, in ? win32file.UnlockFile(fd, 0, 0, 0xffff0000,0) pywintypes.api_error: (33, 'UnlockFile', 'The process cannot access the file because\r\nanother process has locked a portion of the file.') Which is a big improvement over what I was getting before. Unfortunately, I'm just taking blind stabs in the dark. I'm in over my head, and I don't really know what I'm doing. Would getting the Programming Python on Win32 help me learn this Windows API stuff. Or would I have to get a separate book on Windows API and then get the Programming Python on Win32 to help me translate that knowledge into Python? (I have to say, that the msdn documentation is sketchy at best, and I have to do a lot of guesswork.

A quick check over the C++ extension code certainly implies it should work. > win32file.LockFile(fd, win32con.LOCKFILE_EXCLUSIVE_LOCK, 0, 0xffff0000,0) The LockFile documentation states that the first integer "Specifies the low-order word of the starting byte offset in the file where the lock should begin." - ie, it is *not* the flag that LockFileEx supports. Set this to zero. The documentation for UnlockFile states that the unlocked region must be _exactly_ as specified in the LockFile call - hence your error when unlocking - the start offset is not identical. >Would getting the Programming Python on Win32 help me learn this Windows >API stuff. Or would I have to get a separate book on Windows API and then >get the Programming Python on Win32 to help me translate that knowledge into Python? It would not help with this specific corner of the API - file locking is not covered. In general, your best approach is to find documentation or examples in any language, and then use PPW32 to help translate to Python code. I would suggest buying a copy of the MSDN "library" on CD - I don't think it is too expensive, and is a very useful resource, including lots of sample code.

I finally realized, that I can have blocking or non-blocking, but there is only exclusive locks and no shared locks. :I would suggest buying a copy of the MSDN "library" on CD - I don't think it :is too expensive, and is a very useful resource, including lots of sample :code.

You can do all of the above. Look for py2exe (use google to find it) to byte-compile and package up your python program into a single executable plus a small number of .dlls that can simple all be installed in a single directory. The one thing I have not personally done is make a python program run as a win32 service. Other people have.
