Day01课后作业
1、作业要求
编写登录接口
-输入用户名密码
-认证成功后显示欢迎信息
-输错三次后退出
2、流程图
3、程序
#!/usr/bin/env python f = open("foo.txt") #打开用户密码文件 line = f.readline() #读取用户名 line1= f.readline() #读取密码 f.close() #关闭文件 i =1 while i <= 3: input_name = raw_input("Please input your name:") input_passwd = raw_input("Please input your passwd:") if input_name == line[:-1]: #[:-1]的作用是去掉换行符 if input_passwd == line1[:-1]: print "Wecome to linux world,login successfully!" break else: print "you input the passwd is wrong" else: print "you input the name is wrong" i += 1 else: print "you haved try 3 times,no time to try today!!!"
[[email protected] day01]$ cat foo.txt ruizhong.li passwd
4、课上练习程序(待优化)
#!/usr/bin/env python #_*_ coding:utf-8 _*_ #添加此行后,就可以输中文了 print_num = input(‘Which loop do you want it to be printed out?‘) count = 0 while count < 10000000: if count == print_num: print ‘There you got the number:‘,count choice = raw_input(‘Do you want to continue the loop?(y/n)‘) if choice == ‘n‘: break else: while print_num <= count: print_num = input(‘Which loop do you want it to be printed out?‘) if print_num > count: break else: print u‘已经过了,sx!‘ else: print ‘Loop:‘,count count +=1 else: print ‘loop:‘,count
