python - 如何遍历列表并将它们添加到嵌套字典中的值中？

问题描述

player_statistics = 
{'P001': {'G02': ['1'], 'G05': ['0'], 'G07': ['0'], 'G08': ['0'], 'G10': ['1']},
 'P067': {'G02': ['1'], 'G05': ['1'], 'G07': ['0'], 'G08': ['0'], 'G10': ['0']},
 'P218': {'G02': ['0'], 'G05': ['1'], 'G07': ['1'], 'G08': ['0'], 'G10': ['0']},
 'P101': {'G02': ['0'], 'G05': ['0'], 'G07': ['1'], 'G08': ['1'], 'G10': ['0']},
 'P456': {'G02': ['1'], 'G05': ['1'], 'G07': ['0'], 'G08': ['1'], 'G10': ['0']}}

game_info = [
['G05', 'Hopscotch', 'N', '2'],
 ['G07', 'Dominoes', 'S', '5'],
 ['G08', 'Chess', 'N', '3'],
 ['G10', 'Monopoly', 'N', '3'],
 ['G02', 'MineCraft', 'S', '5']
]

我想将 game_info 中每个列表中的 index[2] 和 index[3] 添加到 player_statistics 中的值（列表）中的值。

我的代码：

for values in player_statistics.values():
    for k, v in values.items():
        for data in game_info:
            if k == data[0]:
                player_statistics[k].insert(1, data[2])
                player_statistics[k].insert(2, data[3])

我的代码输出：

Traceback (most recent call last):
  File "D:\projects\FinalCodingChallenge\test.py", line 25, in <module>
    player_statistics[k].insert(1, data[2])
KeyError: 'G02'

预期输出：

player_statistics = 
{'P001': {'G02': ['1', 'S', '5'], 'G05': ['0', 'N', '2'], 'G07': ['0', 'S', '5'], 'G08': ['0', 'N', '3'], 'G10': ['1', 'N', '3']},
 'P067': {'G02': ['1', 'S', '5'], 'G05': ['1', 'N', '2'], 'G07': ['0', 'S', '5'], 'G08': ['0', 'N', '3'], 'G10': ['0', 'N', '3']},
 'P218': {'G02': ['0', 'S', '5'], 'G05': ['1', 'N', '2'], 'G07': ['1', 'S', '5'], 'G08': ['0', 'N', '3'], 'G10': ['0', 'N', '3']},
 'P101': {'G02': ['0', 'S', '5'], 'G05': ['0', 'N', '2'], 'G07': ['1', 'S', '5'], 'G08': ['1', 'N', '3'], 'G10': ['0', 'N', '3']},
 'P456': {'G02': ['1', 'S', '5'], 'G05': ['1', 'N', '2'], 'G07': ['0', 'S', '5'], 'G08': ['1', 'N', '3'], 'G10': ['0', 'N', '3']}}

如果您能解释我在代码上做错了什么，并向我展示适当的方法，我将不胜感激。提前致谢。

解决方案

看起来你错过了keys第一个 for 循环。如果添加它应该可以工作：

for keys, values in player_statistics.items():
    for k, v in values.items():
        for data in game_info:
            if k == data[0]:
                player_statistics[keys][k].insert(1, data[2])
                player_statistics[keys][k].insert(2, data[3])

print(player_statistics)
