python二分法猜数

以下是一个简单的Python二分法猜数的例子：

import random

def binary_search(number, guess_list):
    low = 0
    high = len(guess_list) - 1
    while low <= high:
        mid = (low + high) // 2
        guess = guess_list[mid]
        if guess == number:
            return mid
        if guess > number:
            high = mid - 1
        else:
            low = mid + 1
    return None

if __name__ == '__main__':
    guess_list = list(range(1, 101))
    number = random.randint(1, 100)
    print("请猜测一个1到100之间的数字：")
    while True:
        guess = int(input())
        result = binary_search(guess, guess_list)
        if result is None:
            print("猜错了，请再试一次：")
        elif result == number:
            print("恭喜你，猜对了！")
            break
        elif result < number:
            print("猜小了，请再试一次：")
        else:
            print("猜大了，请再试一次：")
