如何在Python中将两个列表合并为一个但又一个又一个的列表？

Question

我有这份清单：

a = ["1 Monday","1 Wednesday","1 Friday"]
b = ["2 Tuesday","2 Thursday","2 Saturday"]

我想把这些结合起来：

c = ["1 Monday", "2 Tuesday", "1 Wednesday", "2 Thursday", "1 Friday", "2 Saturday"] 

我想轮流做这件事。因此，附加a的第一元素和b的第一元素，然后加上a的第二元素和b的第二元素等等。

Answer 1

您可以将itertools与zip结合使用

In [3585]: import itertools

In [3586]: list(itertools.chain(*zip(a,b)))
Out[3586]: 
['1 Monday',
 '2 Tuesday',
 '1 Wednesday',
 '2 Thursday',
 '1 Friday',
 '2 Saturday']

Answer 2

基本解

list_turn = []
a = ["1 Monday","1 Wednesday","1 Friday"]
b = ["2 Tuesday","2 Thursday","2 Saturday"]
for i in range(len(a)):
    list_turn.append(a[i])
    list_turn.append(b[i])
