从同一个索引中分离出多个单词

Question

我有一个每个索引有多个词的列表，我需要将这些词分成不同的索引。

mylist = ['hell o', 'geg gg' etc...]

如何把上面的列表变成.

newList = ['hell', 'o' , 'geg', 'gg']

Answer 1

In [192]: mylist = ['hell o', 'geg gg']

In [193]: [part for item in mylist for part in item.split()]
Out[193]: ['hell', 'o', 'geg', 'gg']

[part for item in mylist for part in item.split()]

相当于

赋给result的值

result = list()
for item in mylist:
    for part in item.split():
        result.append(part)

Answer 2

另一种方法

>>> from itertools import chain
>>> mylist = ['hell o', 'geg gg']
>>> list(chain.from_iterable(map(str.split, mylist)))
['hell', 'o', 'geg', 'gg']

separating multiple words out of the same index
