Hi Everyone:


How do I rewrite the python script, below, to get a printout from the Maximum to the Minimum, and to convert a string into a number? 






largest = None
smallest = None
while True:
    num = raw_input("Enter a number")
    if num == "done" : break
    print num
    try: 
        inp=raw_input("enter a number:")
        num = float(inp)
    except:
        print "Invalid Input"
    continue
    if smallest is None:
            smallest = value
    elif value < smallest:
  smallest = value
    elif largest is None:
        largest = value
    elif value > largest:
        largest = value
    print "Maximum is", largest
    print "Minimum is", smallest



Regards,

Hal

Hi Everyone:




When the user enters a series of number integers, the output reads:  ?Maximum is None and the ?Minimum is None?




What is the source of the syntax Error, below:




largest = None
smallest = None
while True:
    num = raw_input("Enter a number: ")
    if (num == "done") : break
    try: 
        value = float(num)
    except ValueError:
        print "Invalid input"
    continue
    if smallest is None:
        smallest = value
    elif value < smallest:
  smallest = value
    print smallest, value
    if largest is None:
        largest = value
    elif value > largest:
        largest = value
    print largest, largest
print "Maximum is", largest
print "Minimum is", smallest

Hi Everyone:




I'm trying to write a python program that prompts for a file name, then opens that file and reads through the file, looking for lines of the form: X-DSPAM-Confidence:    0.8475




The program is designed to Count these lines and extract the floating point values from each of the lines and compute the average of those values and produce an output as shown below. 










However, line 10 displays the following string syntax error:




SyntaxError: invalid syntax (<string>, line 10)




The raw URL link to the code is available at

Hi Everyone:


Where can I find documentation on "line.split()"


The Python online documentation site contains no available search term for "line.split()",i.e., URL link at https://www.python.org/downloads/release/python-279/


Moreover, the Python Library Reference refers to the utility function as an ArgumentParser: "def convert_arg_line_to_args(self, arg_line): return arg_line.split()", i.e., The Python Library Reference, Release 2.7.10; 15.4. argparse ? Parser for command-line options, arguments and sub-commands p. 475.


Likewise, the Python Tutorial refers to the utility function as a Generator Expressions: "unique_words = set(word for line in page for word in line.split())?,i.e., Python Tutorial, Release 2.7.10; 9.11. Generator Expressions p. 75

Hi Everyone,


I'm writing python code to read a data text file, split the file into a list of words using the split(function) and to print the results in alphabetical order.


The raw python code is located at http://tinyurl.com/oua9uqx


The sample data is located at 
http://tinyurl.com/odt9nhe



Desired Output: ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'kill', 'light', 'moon', 'pale', 'sick', 'soft', 'sun', 'the', 'through', 'what', 'window', 'with', 'yonder']


There is a line error on no. 7
What is the cause of this error?



Regards,
Hal

Message-ID: <55bacb37.0566420a.f7cc4.ffffb548@mx.google.com>




Hi Everyone,







Question: How do I remove each duplicate line output?







Here is the raw data code:




fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
for line in fh:
    if not line.startswith('From'): continue
    line2 = line.strip()
    line3 = line2.split()
    line4 = line3[1]
    print line4
    count = count + 1            
print "There were", count, "lines in the file with From as the first word"




The problem is in the output results:




Python 2.7.10 |Anaconda 2.3.0 (64-bit)| (default, May 28 2015, 16:44:52) 

[MSC v.1500 64 bit (AMD64)]
