python - 如何按索引合并两个列表

Question

我有两个列表:

i = ['a', 'b', 'c']
x = [1,2,3]

我需要制作这样的字典:

xxx = { 'a': [a, 1],
'b': [b, 2],
'c': [c, 3]}

我这样做了:

for indx in i:
    for indx2 in x:
        xxx.update({indx: [indx, indx2]})

但显然它不起作用

Answer 1

使用字典理解:

>>> i = ['a', 'b', 'c']
>>> x = [1,2,3]
>>> {key: [key, value] for key, value in zip(i, x)}
{'a': ['a', 1], 'c': ['c', 3], 'b': ['b', 2]}
