两个简单应用 code:

# python猜数游戏
from random import *
guessNum = randrange(0, 10000+1)
while True:
    num = input("please input a number which you want to guess. the number between 0 and 10000: ")
    num = int(num)
    if(num == guessNum):
        print("ok, your are right")
        break
    elif(num < guessNum):
        print("oh, so small, please try again")
    else:
        print("oh, so large, please try again")


# python石头剪刀布游戏
# 0：石头
# 1：剪刀
# 2：布
import random
ls = [[0,1,-1], [-1,0,1], [1,-1,0]]
n = int(input("please in enter a number that you want to play: "))
for i in range(n):
    guessNum = random.randrange(3)
    num = input("please input you want: ")
    if(num == "石头"):
        num = 0
    elif(num == "剪刀"):
        num = 1
    else:
        num = 2

    if(ls[num][guessNum] == 1):
        print("you win")
    elif(ls[num][guessNum] == 0):
        print("you draw")
    else:
        print("you lose")
