Another method through re module. 通過re模塊的另一種方法。 It does the reverse operation of matching all the words instead of spitting the whole sentence by space. 它執行匹配所有單詞的反向操作，而不是按空格吐出整個句子。

>>> 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. 上面的正則表達式將匹配一個或多個非空格字符。

Using split() will be the most Pythonic way of splitting on a string. 使用split()將是分裂字符串的最Pythonic方式。

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. 記住如果在沒有空格的字符串上使用split() ，那麼該字符串將在列表中返回給您，這也很有用。

Example: 例：

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

The str.split() method without an argument splits on whitespace: 沒有參數的str.split()方法在空格上拆分：

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

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