二分法猜数字

结合二分法的算法思想来猜数字吧。通过二分法来猜数字可以帮助你每次筛选掉一半错误的数字，提高你的准确率。

import random
num = random.randint(1,100)
count = 7
print("猜数字挑战开始，你有七次机会")
while True:
    guess = int(input("输入你猜的数字："))
    if guess == num:
        print("恭喜你猜对了")
        break
    elif guess > num:
        count -= 1
        print("猜大了")
        print("你还有", count, "次机会")
    elif guess < num:
        count -= 1
        print("猜小了")
        print("你还有", count, "次机会")
    if count == 0:
        print("挑战失败了....")
        print("正确的数字是",num)
        break
