二十四点游戏 python pta

二十四点游戏是一种数字游戏，目的是通过加减乘除的组合，将四个数字计算得到24。

下面是一个用 Python 实现的二十四点游戏代码，可以在 PTA 平台上运行：

import itertools

def calculate(num1, num2, op):
    if op == '+':
        return num1 + num2
    elif op == '-':
        return num1 - num2
    elif op == '*':
        return num1 * num2
    elif op == '/' and num2 != 0:
        return num1 / num2
    return None

def is_valid(num1, num2, num3, num4, ops):
    for p in itertools.permutations([num1, num2, num3, num4]):
        for op1, op2, op3 in itertools.product(ops, repeat=3):
            result1 = calculate(p[0], p[1], op1)
            result2 = calculate(result1, p[2], op2)
            result3 = calculate(result2, p[3], op3)
            if result3 == 24:
                return True
    return False

if __name__ == '__main__':
    num1, num2, num3, num4 = map(int, input().split())
    ops = ['+', '-', '*', '/']
    if is_valid(num1, num2, num3, num4, ops):
        print('Yes')
    else:
        print('No')

代码中使用了 itertools 模块中的 permutations 和 product 函数，用于生成数字和运算符的排列组合。is_valid 函数用于判断给定的四个数字是否可以通过加减乘除得到 24。
