在字典中迭代字典的键时出现错误：0

Question

我想删除每个队得分最低的人。但我总是得到一个键错误：0

Players = {'An': {'Team ':'Red','Score':6 }, 'Jef': {'Team':'Blue','Score': 7 },'Jos': {'Team':'Red','Score':5 }}
names= Players.keys()
for i in range (len(names)):
      if Players[i]["Team"] == Players[i+1]["Team"] :
          if Players[i]['Score'] > PLayers[i+1]['Score']:
            Players.remove(Players[i+1])

有人知道我犯了什么错误吗？（事实上，我知道这段代码效率很低，但对于这个项目，我不能使用大多数Python工具或列表理解）

Answer 1

你应该这样做：

Players = {'An': {'Team':'Red','Score':6 }, 'Jef': {'Team':'Blue','Score':7 },'Jos': {'Team':'Red','Score':5 }}
names = Players.keys()
player_to_remove = []
for i in range(0, len(names) - 1):
    for j in range(i + 1, len(names)):
        if Players[names[i]]['Team'] == Players[names[j]]['Team'] :
            if Players[names[i]]['Score'] < Players[names[j]]['Score']:
                player_to_remove.append(names[i])
            if Players[names[i]]['Score'] > Players[names[j]]['Score']:
                player_to_remove.append(names[j])
for key in player_to_remove:
    del Players[key]

玩家的指纹是： {'Jef'：{'Score'：7，'Team'：'Blue'}，'An'：{'Score'：6，'Team'：'Red'}
