Python 作业

用户登陆v1:

1). 假设系统中的用户名"root",密码为"westos";2). 如果用户输入用户名和密码均正确显示"login ok"    如果用户名错误,显示"user is not exist"    如果密码错误，显示"password is no ok"3). 只有三次登陆机会，超过三次，显示"count is bigger than 3"

#!/usr/bin/env python#coding:utf-8UserName="root"PassWord="westos"for i in range(1,4,1):    check_UserName=raw_input("please input your username:")    check_PassWord=raw_input("please input your passwd  :")    if check_UserName==UserName and check_PassWord==PassWord:        print ("login ok")        exit(0)    elif check_UserName!=UserName:        print ("user is not exist")    elif check_PassWord!=PassWord:        print ("password is no ok")print "count is bigger than 3"

编写乘法表:

#!/usr/bin/env python#coding=utf-8for i in range(1,10):        for j in range(1,i+1):                print '%d*%d=%d'%(i,j,i*j),        print''
