如何对齐此列表中的每个单词? [英] How can I align every word from this list?

问题描述

我在文件中有一个列表列表:

I have a list of lists in a file:

[ [ 'aaaaa', 'bbb','ccccccccc' ], [ 'aaaaa', 'bbbbbb','cccccc' ], [ 'aaa', 'bbb','ccccccccc' ] ]

aaaaa bbb ccccccccc
aaaaa bbbbbb cccccc
aaa bbb ccccccccc

我将其用于某些分析，但是由于单词的长度，很难阅读，我想将其格式化为如下格式:

I use it for some analysis but because of the lengths of the words, it is hard to read, I want to format it to look something like this:

aaaaa  bbb     ccccccccc
aaaaa  bbbbbb  cccccc
aaa    bbb     ccccccccc

在列之间可能会有一些宽敞的空间.

Maybe with some generous spaces between columns.

我想我可以使用 .format 函数，但是我尝试了却没有找到解决方法.

I guess I can use .format function but I tried and I found no solution.

我只能使用Python 2.7.

I can only use Python 2.7.

推荐答案

经过Python2.7测试:

Tested with Python2.7:

lst = [ [ 'aaaaa', 'bbb','ccccccccc' ], [ 'aaaaa', 'bbbbbb','cccccc' ], [ 'aaa', 'bbb','ccccccccc' ] ]

widths = [max(len(j) for j in i) for i in zip(*lst)]
s = ''.join('{{:<{}}}'.format(w+2) for w in widths)

for v in lst:
    print(s.format(*v))

打印与该列内的最大字符串宽度对齐的每列+ 2个额外字符:

Prints each column aligned to max width of string inside this column + 2 extra characters:

aaaaa  bbb     ccccccccc  
aaaaa  bbbbbb  cccccc     
aaa    bbb     ccccccccc
