[docs] [issue25433] whitespace in strip()/lstrip()/rstrip()

[Elliot Edmunds]

Elliot Edmunds <edmundselliot at gmail.com> added the comment:

Not sure how helpful it would be to have the re.sub expressions for lstrip and rstrip, but I think it would look like:

l_stripped = re.sub(r'^\s*', '', foo)
r_stripped = re.sub(r'\s*$', '', foo)
