在python中打印列表输出的最佳方法 [英] Best way to print list output in python

问题描述

我有这样的list和list of list

>>> list2 = [["1","2","3","4"],["5","6","7","8"],["9","10","11","12"]]
>>> list1 = ["a","b","c"]

我压缩了上面两个列表，以便可以按索引匹配它们的值索引.

I zipped the above two list so that i can match their value index by index.

>>> mylist = zip(list1,list2)
>>> mylist
[('a', ['1', '2', '3', '4']), ('b', ['5', '6', '7', '8']), ('c', ['9', '10', '11', '12'])]

现在我尝试使用

>>> for item in mylist:
...     print item[0]
...     print "---".join(item[1])
...

结果是我的desired output.

a
1---2---3---4
b
5---6---7---8
c
9---10---11---12

现在，我的问题是还有一种cleaner and better方式可以达到我想要的输出，或者这是best(short and more readable)可能的方式.

Now, my question is there a more cleaner and better way to achieve my desired output or this is the best(short and more readable) possible way.

推荐答案

好吧，您可以避免一些临时变量并使用更好的循环:

Well, you could avoid some temporary variables and use a nicer loop:

for label, vals in zip(list1, list2):
    print label
    print '---'.join(vals)

不过，我认为您不会从根本上获得更好的收益.

I don't think you're going to get anything fundamentally "better," though.
