python - 如何将集合中的条目更改为整数

Question

我正在尝试将集合的条目更改为整数

我尝试隔离条目并在其上使用“int”函数

contestant = input("Choose a door from the three doors:")
doors = {1,2,3}
prize = random.randint(1,3)
revealable_doors = doors - {int(contestant), int(prize)}
host = int(revealable_doors)

我希望主机将是一个整数，但我不断收到此错误

host = int(revealable_doors)
TypeError: int() argument must be a string, a bytes-like object or a number, not 'set'

Answer 1

revealable_doors = doors - {int(contestant), int(prize)}将返回一个或两个元素的集合。

因此，您不能像在此中所做的那样将 set 转换为 int ：host = int(revealable_doors)

您可以尝试以下代码：

import random
contestant = input("Choose a door from the three doors:")
doors = {1,2,3}
prize = random.randint(1,3)
revealable_doors = doors - {contestant, prize}
host = revealable_doors.pop()
print(host)
