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

我在使用for循环创建类实例时遇到错误“TypeError:无法将'int'object隐式转换为str”。我对编程相当陌生，以前从未见过此错误

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)

当它达到x时，我得到了错误

Answer 1

将整数显式转换为字符串，然后：

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

或使用字符串格式：

^{pr2}$

不能将字符串（player_）和x引用的整数（介于0和Player_count之间的数字）串联起来。在

Answer 2

不能添加字符串和数字

不正确：

["player_" + x]

正确：

^{pr2}$

或新的format方法：

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