Question

在测试中,我有两条刑期。

The heart was made to be broken.
There is no surprise more magical than the surprise of being loved.

该法典:

import re
file = open( /test.txt , r )#specify file to open
data = file.readlines()
file.close()
for line in data:
    line_split = re.split(r [ 	

, ]+ ,line)
    print line_split

Results from the codes:

[ The ,  heart ,  was ,  made ,  to ,  be ,  broken. ,   ]
[ There ,  is ,  no ,  surprise ,  more ,  magical ,  than ,  the ,  surprise ,  of ,  being ,  loved. ]

如何只字面打印? (见第一句) 具体结果:

[ The ,  heart ,  was ,  made ,  to ,  be ,  broken. ]
[ There ,  is ,  no ,  surprise ,  more ,  magical ,  than ,  the ,  surprise ,  of ,  being ,  loved. ]

任何建议?

Answer 1

您不使用<代码>split与划界者匹配,而是使用<代码>findall<>/code>与否定的定期表述相匹配,以便与你想要保持的部件保持一致:

line_split = re.findall(r [^ 	

., ]+ ,line)

见网站:ideone 。

Answer 2

为了确定其他几个变化,进一步解释了:

import re

with open("test.txt", "r") as file:
    for line in file:
        line_split = filter(bool, re.split(r [ 	

, ]+ , line))
        print(line_split)

在此,我们使用 ,删除结果中的任何空示。

words = re.compile(r"[w ]+").findall(yourString)

解散

>>> yourString = "Mary s lamb was white as snow."
["Mary s",  lamb ,  was ,  white ,  as ,  snow ]

If you really do want periods, you can add those as [w .]

In [2]: with open( test.txt , r ) as f:
   ...:     lines = f.readlines()
   ...:

In [3]: words = [l.split() for l in lines]

In [4]: words
Out[4]:
[[ The ,  heart ,  was ,  made ,  to ,  be ,  broken. ],
 [ There ,
   is ,
   no ,
   surprise ,
   more ,
   magical ,
   than ,
   the ,
   surprise ,
   of ,
   being ,
   loved. ]]
