猜数游戏

功能：①机会限制（while循环）②随机生成数字(randint函数)

from random import *

count=0

x=input('请输入难度等级（A,B,C）：')

if x=='A':

    num=randint(0,20)

elif x=='B':

    num=randint(0,50)

elif x=='C':

    num=randint(0,100)

while count <3:

    count=count+1

    usernum=input('请猜随机数：')

    if int(usernum)<num:

        print('猜小了')

    elif int(usernum)>num:

        print('猜大了')

    else:

        print('猜对了')        

    break

else:print('请输入合法字符')

print('您的机会已经用尽，请下次再来')
