for循环

import random
num=random.randint(1,100)
print(num)
for i in range(7):
    guess=input("请输入你要猜的数字：")
    guess=int(guess)
    if guess>num:
        print("猜大了")
    elif guess<num:
        print("猜小了")
    else:
        print("猜对了")
        break
else:
    print("你的次数已经用光了")


如果将代码修改成：num=str(random.randint(1,100))---guess=int(guess)去掉，则数字大于三位数字的时候运行结果和想要的不一致
