python - TypeError：在 for 循环中创建类实例时，无法将“int”对象隐式转换为 str

Question

使用 for 循环创建类实例时，我收到错误“TypeError: Can't convert 'int' object to str implicitly”。我对编程很陌生，以前没有见过这个错误

class Player(object):  
    properties = []
    def __init__( self, name, wealth, player_number):
        self.name = name
        self.wealth = wealth
        self.player_number = player_number
    def __repr__(self):
        return str(self.wealth)

players = {}

for x in range(0, Player_count):
    players["player_" + x] = Player(input("Name"), input("Starting Wealth"), x)

到达 x 时出现错误

Answer 1

然后将整数显式转换为字符串：

 players["player_" + str(x)] = Player(input("Name"), input("Starting Wealth"), x)

或使用字符串格式：

 players["player_{}".format(x)] = Player(input("Name"), input("Starting Wealth"), x)

您不能仅仅连接一个字符串 ( ) 和一个由 引用player_的整数（和 之间的数字0）。Player_countx

Answer 2

您不能添加字符串和数字

不正确：

["player_" + x]

正确的：

['player_%d' % x']

或新format方法：

['player_{0}'.format(x)]
