Stripping Strings

• s.strip([chars]) Return a copy of the string with the leading and trailing characters removed. The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped
• s.lstrip([chars]) like strip(), but only from left side.
• s.rstrip([chars]) like strip() but from right side.

Sometimes strings have trailing or leading characters which have to be removed. In most cases whitespaces.
