ProcessPoolExecutor 传递多个参数

ESPN播放器免费

class ESPNPlayerFree:

def __init__(self, player_id, match_id, match_id_team):
...

团队名单1：

 [('277906', 'cA2i150s81HI3qbq1fzi', 'za1Oq5CGHj3pkkXWNghG'), ('213674', 'cA2i150s81HI3qbq1fzi', 'za1Oq5CGHj3pkkXWNghG')]

Code

 with concurrent.futures.ProcessPoolExecutor(max_workers=30) as executor:
    results = list(executor.map(ESPNPlayerFree, teamList1))

类型错误：__init__() missing 2 required positional arguments: 'match_id' and 'match_id_team'

Since starmap不可用，为此创建一个辅助工厂函数：

def player_helper(args):
    return ESPNPlayerFree(*args)

with concurrent.futures.ProcessPoolExecutor(max_workers=30) as executor:
    results = list(executor.map(player_helper, teamList1))

或者将其制作成classmethod上课ESPNPlayerFree如果它更有意义：

class ESPNPlayerFree:

...
    @classmethod
    def expand_args(cls, args):
        return cls(*args)


with concurrent.futures.ProcessPoolExecutor(max_workers=30) as executor:
    results = list(executor.map(ESPNPlayerFree.expand_args, teamList1))
