将元组转换为字典中的列表 [英] Convert tuple to list in a dictionary

问题描述

我有一本这样的字典:

a= {1982: [(1,2,3,4)],
    1542: [(4,5,6,7),
           (4,6,5,7)]}

，我想将所有元组(1,2,3,4),(4,5,6,7),(4,6,5,7)更改为列表，在这种情况下:[1,2,3,4], [4,5,6,7], [4,6,5,7]

and I want to change the all the tuples (1,2,3,4),(4,5,6,7),(4,6,5,7) to lists, in this case: [1,2,3,4], [4,5,6,7], [4,6,5,7]

我尝试过

for key, value in a.items():
    for i in value:
        i = tuple(i)

但是它现在可以工作了.我该如何实现?

but it does now work. How can I achieve it?

推荐答案

据我了解，您希望转换列表中的每个元组.您可以使用字典理解来做到这一点:

As far as I understand you want to convert each tuple in a list. You can do this using a dictionary comprehension:

{k: [list(ti) for ti in v] for k, v in a.items()}

会给予

{1542: [[4, 5, 6, 7], [4, 6, 5, 7]], 1982: [[1, 2, 3, 4]]}

那是你的追随吗?
