I thank you for your help.
I already used re.split successfully but in this case...
I didn't explain more deeply because I don't want someone else do my
homework.
I want to implement a variable & commands cross reference tool.
For this goal I must clean the python source from any comment and
manifest string.
On the cleaned source file I must isolate all the words (keeping the
words connected by '.')
My wrong code (don't consider the line ref. in traceback ... it's an
extract!):
import re
# input text file w/o strings & comments
f=open('file.txt')
lInput=f.readlines()
f.close()
fOut=open('words.txt','w')
for i in lInput:
. ll=re.split(r"[\s,{}[]()+=-/*]",i)
. fOut.write(' '.join(ll)+'\n')
fOut.close()
Traceback (most recent call last):
File "./GetWords.py", line 70, in ?
ll=re.split(r"[\s,{}[]()+=-/*]",i)
File "/usr/lib/python2.3/sre.py", line 156, in split
return _compile(pattern, 0).split(string, maxsplit)
RuntimeError: maximum recursion limit exceeded
... and if I use:
ll=re.split(r"\s,{}[]()+=-/*",i)
Traceback (most recent call last):
File "./GetWords.py", line 70, in ?
ll=re.split(r"\s,{}[]()+=-/*",i)
File "/usr/lib/python2.3/sre.py", line 156, in split
return _compile(pattern, 0).split(string, maxsplit)
File "/usr/lib/python2.3/sre.py", line 230, in _compile
raise error, v # invalid expression
sre_constants.error: bad character range
I taught it was my mistake in the use of re.split...
I am using:
