python里如何猜数

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{}～{}之间您猜测的数字：".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))

        if guess < answer:

            print("猜小了")

        elif guess == answer:

            print("猜对了")

            history[name].append("成功")

            break

        elif guess > answer:
