如何让班里的新人成为玩家？

Question

我这里有一个程序，我做了，我试图添加一个新的球员。每次我尝试的时候都会出现错误，有没有人能帮帮我？提前谢谢你，-Josh

          def main():
            class Player:
                def __init__(self, name, tank_name):
                    self.name = name
                    self.tank_name = tank_name
            def new_player():
                p1 = Player()
                p1.name = input('What is your name >>> ')
                p1.tank_name = input('What is your tanks name >>> ')
            new_player()
        
        if __name__ == '__main__':
            main()

Answer 1

name和tank_name是__init__方法的必需参数。您需要在创建Player之前请求它们，而不是在创建之后分配它们。

class Player:

    def __init__(self, name, tank_name):
        self.name = name
        self.tank_name = tank_name

def new_player():
    name = input('What is your name >>> ')
    tank_name = input('What is your tanks name >>> ')
    p1 = Player(name, tank_name)

new_player()

Answer 2

对于__init__方法，还可以将name和tank_name参数设置为None

    def main(): 
        class Player:
                    def __init__(self, name=None, tank_name=None):
                        self.name = name
                        self.tank_name = tank_name
                def new_player():
                    p1 = Player()
                    p1.name = input('What is your name >>> ')
                    p1.tank_name = input('What is your tanks name >>> ')
                new_player()
            
   if __name__ == '__main__':
       main()
