要求的输出

Question

我有一个像这样的列表

[[{1:"one",2:"two"},{1:"one"}],[{3:"three",4:"four"},{3:"three"}]]

必需的输出：

[{1:"one",2:"two"},{1:"one"},{3:"three",4:"four"},{3:"three"}]

有人可以告诉我如何继续吗？

Answer 1

迭代列表的列表，将其添加到另一个列表中。

list_1 = [[{1:"one",2:"two"},{1:"one"}],[{3:"three",4:"four"},{3:"three"}]]
list_2 = []
for list in list_1:
    for dictionary in list:
        list_2.append(dictionary)

print(list_2)  # [{1: 'one', 2: 'two'}, {1: 'one'}, {3: 'three', 4: 'four'}, {3: 'three'}]

Answer 2

你可以试试这个：

from itertools import chain

l = [[{1:"one",2:"two"},{1:"one"}],[{3:"three",4:"four"},{3:"three"}]]

new_l = list(chain(*l))

最终输出：

[{1: 'one', 2: 'two'}, {1: 'one'}, {3: 'three', 4: 'four'}, {3: 'three'}]
