If you want to look at stuff that can't be implemented trivially using
str/unicode methods, and is more than a bit useful, google for
mxTextTools.

Not quite. I said "whitespace", not "space".
The following is the standard Python idiom for removing leading and
trailing whitespace and replacing one or more whitespace characters
with a single space:
def normalise_whitespace(s):
return ' '.join(s.split())
If your data is obtained by web scraping, you may find some people use
'\xA0' aka NBSP to pad out fields. The above code will get rid of
these if s is unicode; if s is str, you need to chuck
a .replace('\xA0', ' ') in there somewhere.
