如何在 python 中猜测数字

import mathimport random#历史记录history = {}def input_guess(start,end):
    """输入数字并判断是否在范围之内"""
    guess = int(input("请输入{}～{}之间你猜测的数字：".format(start,end)))
    if guess >= start and guess <= end:
        return guess    
    else:
        print("输入非法数字，重新输入,请确认数字在{}～{}之间".format(start,end))
        input_guess(start,end)def begin():
    """开始游戏"""
    name = input("请输入姓名：")
    
    #①将输入的字符串转换成列表
    start, end = input("请输入猜测数字的范围，用，分隔：").split(',')
    start,end = int(start),int(end)
    #检查用户名是否存在，如果不存在，创建用户
    if name not in history.keys():
        history[name] = []
    
    #②randrange里的参数必须是数字
    answer = random.randrange(start,end+1)
    times = math.log2(start+end)
    times = math.floor(times)
    count = 0
    print("请在{}次内猜测正确数字".format(times))


    #循环times次判断输入数字是否猜对
    while count < times:
        guess = input_guess(start, end)
        if guess < answer:
            print("猜小了")
        elif guess == answer:
            print("猜对了")
            history[name].append("成功")
            break
        elif guess > answer:
            print("猜大了")
        count += 1
    else:
        print("猜测次数太多，游戏失败,正确答案为{}".format(answer))
        history[name].append("失败")
    main()def main():
    print("1.历史记录")
    print("2.继续游戏")
    print("3.退出游戏")
    choice = input("输入数字选择：")

    if choice == "1":
