Split string on whitespace in Python

The str.split() method without an argument splits on whitespace:

>>> "many   fancy word \nhello    \thi".split()
['many', 'fancy', 'word', 'hello', 'hi']

import re
s = "many   fancy word \nhello    \thi"
re.split('\s+', s)

Using split() will be the most Pythonic way of splitting on a string.

It's also useful to remember that if you use split() on a string that does not have a whitespace then that string will be returned to you in a list.

Example:

>>> "ark".split()
['ark']

Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.

>>> import re
>>> s = "many   fancy word \nhello    \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']

Above regex would match one or more non-space characters.
