我需要将列表转换为熊猫数据框的帮助

如何解决我需要将列表转换为熊猫数据框的帮助

我正在尝试从Riot Game的API中提取数据并填充用于机器学习的数据框，但是我很难将数据提取格式转换为我的数据框。数据框中的每一行代表一个玩家玩的游戏。使用以下示例字典语法从API中提取特定的“单位”数据：

{'name': 'DarkStar','num_units': 6,'style': 3,'tier_current': 3,'tier_total': 4}
{'name': 'Infiltrator','num_units': 1,'style': 0,'tier_current': 0,'tier_total': 3}
{'name': 'Protector','num_units': 2,'style': 1,'tier_current': 1,'tier_total': 3}

我希望每个游戏都有14个左右的列，每个“名称”都有一个列，值=“ num_units”。我从字典中仅提取了需要的数据，以方便访问：

[('Chrono',2),('Cybernetic',('DarkStar',1)]

我的问题是：我该如何编程，以便每一列都有其对应的'num_units'填充（包括零，其中在游戏过程中未使用任何特征类型）？例如，假设三种特质类型是游戏中唯一使用的特质，“计时”，“ Cybernetic”和“暗星”将分别具有其对应的num_units，其余9个特质将具有“ 0”。我的代码在下面，感谢您的帮助，因为我仍然很陌生。

placements = []
total_damage_dealt = []
trait_names = []
unit_values = []
rounds_lasted = []
game_length = []
game_ids = []

for game in game_request:
    game_ids.append(game)
    total_game_data = requests.get("https://americas.api.riotgames.com/tft/match/v1/matches/"+game+"?api_key=hidden")
    total_game_data = total_game_data.json()
    all_player_game_data = total_game_data['info']
    length = all_player_game_data['game_length']
    game_length.append(length)
    participants = all_player_game_data['participants']
    for participant in participants: #checks to see if user in list = target user
        if participant['puuid'] == puuid:
            unit_names = []
            unit_qtys = []
            placements.append(participant['placement'])
            rounds_lasted.append(participant['last_round'])
            total_damage_dealt.append(participant['total_damage_to_players'])
            traits = participant['traits']
            for i in range(len(traits)):
                unit = traits[i]
                unit_names.append(unit.get('name'))
                unit_qtys.append(unit.get('num_units'))
            trait_total = list(zip(unit_names,unit_qtys))
        else:
            pass

编辑以下是game_request和total_game_data的示例。我正在尝试获取total_game_data中的值。

游戏：
