Python questions OT

[Art Kendall]

This is OT but I know that there are some PYTHON users on this list and I am finally getting back to starting with python after a long delay.

1) Is there a PYTHON list someplace?

2) Where would I find the documentation for Python error numbers?

3) My python that starts with this
import re, textwrap
# read the combined file and split into individual papers
alltext = file("C:\Users\Art\Desktop\fed\feder16v2.txt").readlines()
papers= re.split(r'FEDERALIST No\.'," ".join(alltext))
print len(papers)

outfile = file("C:\Users\Art\desktop\fed\federalistCounts.txt", "w")
 
words = """A                  
ABANDON            
ABANDONED  
. . .
ZEALAND            
ZEALOUS              """

gets this error message:

>>>
Traceback (most recent call last):
  File "C:\Users\Art\Desktop\fed\countFedWords.py", line 5, in <module>
    alltext = file("C:\Users\Art\Desktop\fed\feder16v2.txt").readlines()
IOError: [Errno 22] invalid mode ('r') or filename: 'C:\\Users\\Art\\Desktop\x0ced\x0ceder16v2.txt'
>>>

the filespec python does not seem to like is not what is in the code.   Also the file does exist. 

4) The list of words is now hard coded in the python code.

How would I replace
words = """A                  
ABANDON            
ABANDONED  
. . .
ZEALAND            
ZEALOUS              """

with a command to read the list from another file?

This is OT but I know that there are some PYTHON users on this list and I am finally getting back to starting with python after a long delay.

1) Is there a PYTHON list someplace?
There is a version active Python language list at http://groups.google.com/group/comp.lang.python/topics
but they won't know much about SPSS in particular.  Besides this list, you can post to the forums at Developer Central

2) Where would I find the documentation for Python error numbers?
>>>The Python language and standard library generally don't use error numbers.  Some SPSS messages do, but there is no additional documentation for these.

3) My python that starts with this
import re, textwrap
# read the combined file and split into individual papers
alltext = file("C:\Users\Art\Desktop\fed\feder16v2.txt").readlines()
papers= re.split(r'FEDERALIST No\.'," ".join(alltext))
print len(papers)

outfile = file("C:\Users\Art\desktop\fed\federalistCounts.txt", "w")

words = """A                  
ABANDON            
ABANDONED  
. . .
ZEALAND            
ZEALOUS              """

gets this error message:

IOError: [Errno 22] invalid mode ('r') or filename: 'C:\\Users\\Art\\Desktop\x0ced\x0ceder16v2.txt'
>>>

the filespec python does not seem to like is not what is in the code.   Also the file does exist.  

>>>In Python strings, escape sequence such as \f are interpreted as special characters - in this case a form feed.  To avoid this,
 - use forward slashes (even for paths), or
 - precede the whole string with r for raw, e.g., r"\feder16", or
 - double the slash, e.g., "desktop\\fed

4) The list of words is now hard coded in the python code.

How would I replace
words = """A                  
ABANDON            
ABANDONED  
. . .
ZEALAND

with a command to read the list from another file?

>>>One way
f = open(filespec)
mylist = f.readlines()
mylist = [item.rstrip("\n") for item in mylist]

This time you do want the \n to be interpreted as a newline character.

Hi Art,

 

I am subscribed to Python Tutor, which I find (given my level of experience with Python) more useful than the general Python mailing list. http://mail.python.org/mailman/listinfo/tutor

I never asked anything specific to the spss modules for python there. DevCentral or Spss-L is the place for such questions.

Cheers!!
Albert-Jan

hi!

Do you mean something like this?

import os.path

def splitPaper (filespec, splitTerm):
    return open(filespec, "rb").read().split(splitTerm)

def splitPapers(filespec, splitTerms):
    for splitTerm in splitTerms:
        for cnt, splitted in enumerate(splitPaper(filespec, splitTerm)):
            fn = os.path.join(os.path.dirname(filespec), splitTerm + str(cnt+1).zfill(2) + ".txt")
            open(fn, "wb").write("".join(splitted))
    print "Done!"

splitPapers(filespec = "d:/temp/somefile.txt", splitTerms = ("and", "or", "some phrase"))


Cheers!!

Thank you.  That worked.
