python - Flask TypeError：字符串索引必须是整数

问题描述

我的 Flask 项目中的 delete 方法出现此错误。 TypeError：字符串索引必须是整数

我该如何解决？

def delete(self,player_name):
        global nba_players_json
        nba_players_json = list(filter(lambda x : x['name'] != player_name, nba_players_json))
        return {'message' : 'Item deleted'}

这是我的字典的样子：

"AJ Price": {
        "Name": "AJ Price",
        "Games Played": "26",
        "MIN": "324",
        "PTS": "133",
        "FGM": "51",
        "FGA": "137",
        "FG%": "37.2",
        "3PM": "15",
        "3PA": "57",

def delete(player_name):
        global nba_players_json
        if player_name in nba_players_json:
          del nba_players_json[player_name]
          return {'message' : 'Item deleted'}
        else:
          return {'message' : 'Item not deleted'}

print(delete('AJ Price'))
