看不到语法问题

我正在尝试将每个游戏（g）中每个玩家（p）得分的点数保存到由其对手锁定的字典中。我在以下代码中遇到语法问题：

opponents = {}
for p in range(len(league_data['elements'])):
    for g in range(len(game_data[str(league_data['elements'][p]['id'])]['history'])):
        #skip games where the player played 0 minutes
        if game_data[str(league_data['elements'][p]['id'])]['history'][g]['minutes'] == 0: continue
        opp = team_list[game_data[str(league_data['elements'][p]['id'])]['history'][g]['opponent_team']
        points = game_data[str(league_data['elements'][p]['id'])]['history'][g]['total_points']
        opponents.setdefault(opp, [0,0])[0] += points
        opponents[opp][1] += 1

我在以下行收到错误：

points = game_data[str(league_data['elements'][p]['id'])]['history'][g]['total_points']
     ^
SyntaxError: invalid syntax

但是我看不到问题。另外，如果我在单独的单元格中写出该行并打印`points'，则效果很好。
