坚持制作一个通过 class 将玩家附加到列表的程序

Question

它打印的不是从列表中打印播放器变量：

[<__main__.Player object at 0x7f95614f4ee0>, <__main__.Player object at 0x7f95614f4f70>, 
 <__main__.Player object at 0x7f9561520400>]

代码：

class Player:
    def __init__(self, name, swaps, points):
        self.player_name = name
        self.player_swaps = swaps
        self.player_points = points

def add_player(players):
    name = input('Enter the new players Name : ')
    swaps = 3
    points = 0
    players.append(Player(name, swaps, points))
    print('Player Added \n')

def playerselector():
    '''Input for players to choose how many players they want.
    Will tell them if not sensible and get them to do it again.
    '''
    valid = False
    while valid is False:
        try:
            num_players = int(input("How many players do you want? (2-5)\n"))
            if num_players >= 2 and num_players <= 5:
                valid = True
            else:
                print("Please choose a number between 2 and 5")
        except ValueError:
            print("Sorry that isn't a number")
    return num_players

num_players = playerselector()
players=[]

for x in range(num_players):
    add_player(players)

print(players)

任何tips/solutions？

Answer 1

这应该有效：

class Player:

    def __init__(self, name, swaps, points):
        self.player_name = name
        self.player_swaps = swaps
        self.player_points = points
    def __repr__(self):
        rep = f'Player({self.player_name}, {self.player_swaps}, {self.player_points})'
        return rep

def add_player(players):
    name = input('Enter the new players Name : ')
    swaps = 3
    points = 0
    players.append(Player(name, swaps, points))
    print('Player Added \n')

def playerselector():
    valid = False
    while valid is False:
        try:
            num_players = int(input("How many players do you want? (2-5)\n"))
            if num_players >= 2 and num_players <= 5:
                valid = True
            else:
                print("Please choose a number between 2 and 5")
        except ValueError:
            print("Sorry that isn't a number")
    return num_players


num_players = playerselector()
players=[]

for x in range(num_players):
    add_player(players)

print(players)

输出：

How many players do you want? (2-5)
 3
Enter the new players Name :  bob
Player Added 

Enter the new players Name :  joe
Player Added 

Enter the new players Name :  tom
Player Added 

[Player(bob, 3, 0), Player(joe, 3, 0), Player(tom, 3, 0)]

您可以更改 __repr__ 方法中的 rep 变量来修改输出。您可以了解有关 __repr__ 及其用途的更多信息 here

Answer 2

在class中添加player_return功能：

def player_return(self):
    return [self.player_name,self.player_swaps, self.player_points]

并在 add_player()

中调用它

A=Player(name, swaps, points)
players.append(A.player_return())

输出

How many players do you want? (2-5)
2
Enter the new players Name : tim
[['tim', 3, 0]]
Player Added

Enter the new players Name : Jerry
[['tim', 3, 0], ['Jerry', 3, 0]]
Player Added
[['tim', 3, 0], ['Jerry', 3, 0]]
