[已解决].split的问题

汤米露

这个是我的code:
data=open('E:\\something.txt','r')
for each_line in data:
    (role,line_spoken)=each_line.split(':',1)
print (role)
print (line_spoken)

something.txt里面的内容
Man : Is this the right room for an argument?
Other Man : I've told you once.
Man : No you haven't!
Other Man : Yes I have.
Man : When?
Other Man : Just now.

当我打印了role和line_spoken，分别赋予了Other Man和Just now.
我想问的是，为什么6句话中，只有最后一句被拆分了，而不是每句话都被拆分。

你可以在role的后面加上strip(),去掉前后的空格。

1. data=open('f:\\1.txt','r')
   
2. man = []
   
3. oman = []
   
4. 
   
5. for each_line in data:
   
6.    (role, line_spoken)=each_line.split(':',1)
   
7.     if role.strip() == 'Man':
   
8.         man.append(line_spoken)
   
9.     if role.strip() == 'Other Man':
   
10.         oman.append(line_spoken)

复制代码

>>> man
[' Is this the right room for an argument?\n', " No you haven't!\n", ' When?\n']
>>> oman
[" I've told you once.\n", ' Yes I have.\n', ' Just now.']
>>>

这样就可以了。

你的打印语句是放在循环外的，只会打印最后一次的结果。

1. data=open('f:\\1.txt','r')
   
2. for each_line in data:
   
3.     (role,line_spoken)=each_line.split(':',1)
   
4.     print (role)
   
5.     print (line_spoken)

复制代码

这样的话就可以打印出所有
======== RESTART: F:\Python\procedure\if.py ========
Man
Is this the right room for an argument?

Other Man
I've told you once.

Man
No you haven't!

Other Man
Yes I have.

Man
When?

Other Man
Just now.

其实呢，我是想把Man和Other Man的对话储存到两个变量man和oman里面去，但是我最终运行下面程序的时候，man和oman还是空的。请问这是为何呢？
data=open('E:\\something.txt','r')
man = []
oman = []

for each_line in data:
    (role,line_spoken)=each_line.split(':',1)
    if role == 'Man':
        man.append(line_spoken)
    if role == 'Other Man':
        oman.append(line_spoken)

这样就可以了。
