python遍历字符串并重组,Python：循环遍历字符串列表并使用split（）

I'm trying to split the elements of a list:

text = ['James Fennimore Cooper\n', 'Peter, Paul, and Mary\n',

'James Gosling\n']

newlist = ['James', 'Fennimore', 'Cooper\n', 'Peter', 'Paul,', 'and', 'Mary\n',

'James', 'Gosling\n']

My code so far is:

newlist = []

for item in text:

newlist.extend(item.split())

return newlist

And I get the error:

builtins.AttributeError: 'list' object has no attribute 'split'

解决方案

Don't use split() here as it'll also strip the trailing '\n', use split(' ').

>>> text = ['James Fennimore Cooper\n', 'Peter, Paul, and Mary\n',

... 'James Gosling\n']

>>> [y for x in text for y in x.split(' ')]

['James', 'Fennimore', 'Cooper\n', 'Peter,', 'Paul,', 'and', 'Mary\n', 'James', 'Gosling\n']

And in case the number of spaces are not consistent then you may have to use regex:

import re

[y for x in text for y in re.split(r' +', x)]]
