1、游戏要求

# 实现人机对战石头剪刀布
# 需求：实现用户登录并可以定义用户昵称
# 可以选择对战英雄
# 实现石头剪刀布对决（七局四胜制）
# 实现遇到恶意用户警告处理或者强制退出
# 要求打印最终对战结果，公布比赛胜负

# 导入外部函数，后续调用

import random

# 选英雄的方法

# 保证定义要在调用之前

def selectHero():
    # 英雄定义
    hero = int(input("请输入您的对手：1.唐三 2.箫炎 3.易烊千玺 4.亚瑟 5.游乐王子\n"))

        print("您的对手是唐三")
        heroName = "唐三"
