??????? if input == 'alex':
 
??????????????? password = raw_input("Please input your passwd:")
 
??????????????? p = '123'
 
??????????????? while password != p:
 
??????????????????????? password =raw_input("Wrong passwd,Please input again:")
 
??????????????? else:

??????????????????????????????? contact_file = file('contact_list.txt')
 
??????????????????????????????? while True:
 
??????????????????????????????????????? line = contact_file.readline()
 
??????????????????????????????????????? if len(line) == 0:break
 
??????????????????????????????????????? if input != ""and input in line:

??????????????????????????????????????????????? match_yes = 1
 
??????????????????????????????? if match_yes == 0 :print 'No match item found'
 
??????? else:

脚本注释:

#!/usr/bin/python

while True: #开启输入用户的循环

input = raw_input(“Please input your username:”) #定义一个变量用来存储输入的用户

if input == ‘alex’: #判断输入的用户名是否是alex,如果是alex,则让用户输入密码

password = raw_input(“Please input your passwd:”) #定义变量用来存储输入的密码

p = ‘123’ #定义用户的密码是123

while password != p:

password =raw_input(“Wrong passwd,Please input again:”) #当输入的密码不是123的时候,提示密码不正确,并且一直让用户输入密码

else:

print ‘Welcome login to TRiAquae!\n’? #当输入的密码是123的时候,提示欢迎信息

while True:?? #进入一个新的循环,用于判断用户输入的查找内容

match_yes = 0? #设置查找标记为0

input = raw_input(“\033[32mPlease input the username you want to search:\033[0m”) #定义变量用于存储用户的查找内容

contact_file = file(‘contact_list.txt’) #定义一个变量用来存储读取的文件内容

while True: #遍历文件内容

line = contact_file.readline() #定义变量存放读取文件的每一行内容

if len(line) == 0:break?? #判断文件是否读完,当行的长度为0时,文件已经读完了,则跳出遍历每行文件

if input != “” and input in line:

print ‘Match item: \033[36;1m%s\033[0m’ % line #如果输入的内容不为空,并且匹配到了某行,则打印这一行的内容

match_yes = 1 #设置查找到的标记为1

if match_yes == 0 :print ‘No match item found’ #如果没有匹配到,则打印没有内容找到

else:

print “Sorry,user %s not found” % input? #如果用户名不是alex,则打印用户名没有找到,并且一直让用户输入用户名
