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
