如何用python3代码玩小游戏？

import random

rang1 = int(input("请设置本局游戏的最小值:"))

rang2 = int(input("请设置本局游戏的值:"))

num = random.randint(rang1,rang2)

guess = "guess"

print("数字猜谜游戏！")

i = 0

while guess != num:

    i += 1

    guess = int(input("请输入你猜的数字："))

    if guess == num:

        print("恭喜，你猜对了！")

    elif guess < num:

        print("你猜的数小了...")

    else:

        print("你猜的数大了...")

print("你总共猜了%d" %i + "次",end = '')

print(",快和你朋友较量一下...")
