Question

我想在Python中合并两个或多个字典。我想要一本普通的字典，里面还有另一本字典。

common_dic = {}

for y in range(1,3):
    for i in range(1,4):
        tmp_dic = {}
        if i is 1:
            tmp_dic["one"] = i
        if i is 2:
            tmp_dic["two"] = i
        if i is 3:
            tmp_dic["three"] = i

我打印common_dic时的预期结果是

({'one': 1, 'two': 2, 'three': 3}, {'one': 1, 'two': 2, 'three': 3})

当我使用json格式输出时

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

有什么想法吗？

基于新编辑的解决方案。我们正在创建字典并将其附加到列表中。因此，结果是字典列表。

common_dic = []

for y in range(1,3):
    tmp_dic = {}
    for i in range(1,4):
        if i is 1:
            tmp_dic["one"] = i
        if i is 2:
            tmp_dic["two"] = i
        if i is 3:
            tmp_dic["three"] = i
    common_dic.append(tmp_dic)

print(common_dic)
# Output: [{'one': 1, 'two': 2, 'three': 3}, {'one': 1, 'two': 2, 'three': 3}]
