需要在数组中复制dict数据

Question

json_data = {"map":[{"name":"test"}]}


def replicator(data, replica=1):
    final_data = {}
    for each_map_tcs in data.keys():
        for each_tc in data[each_map_tcs]:
            for i in range(replica):
                if each_map_tcs not in final_data.keys():
                    final_data[each_map_tcs] = []

                final_data[each_map_tcs].append(each_tc)
                each_tc['name'] += '-' + str(i)

    print(final_data)   

replicator(json_data, 2)

实际输出：{'map'：{'name'：'test-01'}，{'name'：'test-01'}}

所需输出：{'map'：{'name'：'test-0'}，{'name'：‘test-1’}

Answer 1

import copy

json_data = {"map":[{"name":"test"}]}


def replicator(data, replica=1):
    final_data = {}
    for each_map_tcs in data.keys():
        for each_tc in data[each_map_tcs]:
            for i in range(replica):
                if each_map_tcs not in final_data.keys():
                    final_data[each_map_tcs] = []

                tmp_dict = copy.deepcopy(each_tc)
                tmp_dict['name'] += '-' + str(i)
                final_data[each_map_tcs].append(tmp_dict)

    print(final_data)   

replicator(json_data, 2)

Answer 2

看起来，您只是想要创建一个list-of-dicts，作为更大的dict的值。

列表部分可以用list comprehension创建，然后您可以将其合并到dict中，如下所示：

l = [{'name': 'test-0' + str(x)} for x in range(2)]
d = {'map':l}
print(d)

结果：

{'map': [{'name': 'test-00'}, {'name': 'test-01'}]}
