Python的文件列出

Question

所以我有文件：

Ben cat 15 
John dog 17 
Harry hamster 3 

如何讓3名名單：

[Ben, John, Harry] 
[cat, dog, hamster] 
[15, 17, 3] 

我已經嘗試了一切，但我還沒有找到一個解決辦法呢。

我使用Python 3.3.0

Answer 1

with open("file.txt") as inf: 
    # divide into tab delimited lines 
    split_lines = [l[:-1].split() for l in inf] 
    # create 3 lists using zip 
    lst1, lst2, lst3 = map(list, zip(*split_lines)) 

Answer 2

gsi-17382 ~ $ cat file 
Ben cat 15 
John dog 17 
Harry hamster 3 
gsi-17382 ~ $ python 
Python 2.7.2 (default, Jun 20 2012, 16:23:33) 
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin 
Type "help", "copyright", "credits" or "license" for more information. 
>>> zip(*[l.split() for l in open('file')]) 
[('Ben', 'John', 'Harry'), ('cat', 'dog', 'hamster'), ('15', '17', '3')] 
>>> names, animals, numbers = map(list, zip(*[l.split() for l in open('file')])) 
>>> numbers = map(int, numbers) 
>>> names 
['Ben', 'John', 'Harry'] 
>>> animals 
['cat', 'dog', 'hamster'] 
>>> numbers 
[15, 17, 3] 

Answer 3

以下：

ll = [l.split() for l in open('file.txt')] 
l1, l2, l3 = map(list, zip(*ll)) 
print(l1) 
print(l2) 
print(l3) 

生產：

['Ben', 'John', 'Harry'] 
['cat', 'dog', 'hamster'] 
['15', '17', '3']
