Just a caveat with the non-qualified strip/rstrip/lstrip...it
will remove *all* whitespace, so if, for some reason, it's
significant, and you only want to remove newlines, you have to
specify it:
>>> s = ' some text \t\n'
>>> s.strip()
'some text'
>>> s.rstrip()
' some text'
>>> s.rstrip('\n')
' some text \t'
As the OP was talking about file-names, the use of
initial/terminal spaces is allowable (albeit imprudent),
depending on your platform, so one may or may not want to strip
them off.
Fortunately, as in many other areas, Python offers the
flexibility in an easy-to-use way, and comes with sensible defaults.
