尝试按索引访问列表时出现 Python 错误 - "List indices must be integers, not str"

Question

我有以下 Python 代码:

currentPlayers = query.getPlayers()
    for player in currentPlayers:
        return str(player['name'])+" "+str(player['score'])

我收到以下错误:

TypeError: list indices must be integers, not str

我一直在寻找与我接近的错误，但不知道该怎么做，从未遇到过该错误。所以是的，我怎样才能将它转换为整数而不是字符串？我猜问题出在 str(player['score']).

Answer 1

您是否希望 player 成为 dict 而不是 list？

>>> player=[1,2,3]
>>> player["score"]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not str
>>> player={'score':1, 'age': 2, "foo":3}
>>> player['score']
