Re: RE Despair - help required
Thank you all guys. It seems like the simpler the solution, the more I am happy about it. Sorry, for the simple question, I am quite new to this lang. Cheers.

Did you actually look at the docs Fredrik pointed you at? Did you,
in particular, notice os.path.basename, which does (almost) exactly
what you want?

Hi, > Don't think it will do much good. I need to get them from a file and > extract the last folder in the path. For example: > if I get "c:\dos\util" > I want to extract the string "\util" Still, os.path is your friend: import os filepath = r'C:\dos\util' base, last = os.path.split(filepath) print base # 'C:\dos' print last # 'util' print os.sep+last # '\util' Don't forget to read > > http://docs.python.org/lib/module-os.path.html for some more info!

like frederik says (I use '/' as I am using Unix):
>>> import os
>>> os.path.split ('c:/foo/bar')
('c:/foo', 'bar')
>>> os.path.splitext ('c:/foo/bar')
('c:/foo/bar', '')
>>> os.path.splitext ('c:/foo/bar.txt')
('c:/foo/bar', '.txt')
or if you are really reluctant:
>>> 'c:\\foo\\bar'.split ('\\')
['c:', 'foo', 'bar']
>>> 'c:\\foo\\bar'.split ('\\') [-1]
'bar'

Re: RE Despair - help required
Don't think it will do much good. I need to get them from a file and
extract the last folder in the path. For example:
if I get "c:\dos\util"
I want to extract the string "\util"

Re: RE Despair - help required
Thanks guys. Issue solved.
I am also going to give Microsoft a call about it. Any other issues you
want me to raise while I am talking to them?
Cheers.

instead of struggling with weird REs, why not use Python's standard
filename manipulation library instead?

Because you don't match a carriage return "\r".

Use forward slashes instead of backward slashes. And go nag at
Microsoft for using the most widely used escape character as a path
separator...

Look at the second string. It has "\r" in the middle of it where you
really want "\\r" (or alternatively r"c:\ret_files").
