Python 2.4.3 on Red Hat 5. Trying to use strip to remove characters

What do you expect it to do?
res = subprocess.Popen(['uname', '-a'], stdout=subprocess.PIPE)
uname = res.stdout.read().strip()
uname
'Linux myserver 2.6.18-274.el5PAE #1 SMP Fri Jul 8 17:59:09 EDT 2011
i686 i686 i386 GNU/Linux'
uname.strip(':')
'Linux myserver 2.6.18-274.el5PAE #1 SMP Fri Jul 8 17:59:09 EDT 2011
i686 i686 i386 GNU/Linux'
'www.example.com'.strip('cmowz.')
'example'
Thoughts?

Help on built-in function strip:
strip(...)
S.strip([chars]) -> string or unicode
Return a copy of the string S with leading and trailing
whitespace removed.
If chars is given and not None, remove characters in chars instead.
If chars is unicode, S will be converted to unicode before stripping
So it appears that your examples are doing precisely what is defined above.
HTH.
