Python basic exercise, query text content and output;

1. Write the Employee Information table that can be queried by the user:

1). user authentication (enter user name, password)

2). Search Keywords: name

3). Display Id,name,section,phone

4). The Employee Information table reads as follows:

Cat Search_name.txt

001wenlong IT12345678  

002xiaojun IT12345678

003ankang IT12345678

004xiang IT12345678

The script is as follows:

#!/usr/bin/pythonwhile true:            # Into the dead Loop         input = raw_input (' Please input your  username: ')      #交互式输入用户信息, enter input information;         if input ==  "Wenlong":         # Enter this loop if input equals Wenlong (if the user enters Wenlong)                  password = raw_input (' Please input your pass: ')       #交互式信息输入, enter password information;                 p =  ' 123 '                     #设置变量P赋值为123                  while password != p:          #如果输入的password   Not equal to P (123),  into the loop                          password = raw_input (' Please input  your pass again: ')      #交互式信息输入, enter password information;                 if password == p:          #如果password等于p (123), enter this loop                          print  ' welcome to select system! '                #输出提示信息;                         while true:             #进入循环;                                 match =  0      #设置变量match等于0;                                  input = raw_input ("Please input the name whom  you want to search : ")     #交互式信息输入, enter input information;                                  while not input.strip ():     #判断input值是否为空, if the input output is empty, enterCyclic;                                          input = raw_input ("Please input the name whom  you want to search : ")          #交互式信息输入, Enter input information;                                 name_file  = file (' search_name.txt ')       #设置变量name_file, file (' Search_name.txt ') is to invoke the document named Search_name.txt                                   while true:                #进入循环;                                          line =  Name_file.readline ()             #以行的形式, read Search_ Name.txt Document Information;                                          if len (line)  == 0:       #当len (Name_file.readline ()  ) is 0 o'clock, indicating that the file has been read, Len (Name_file.readline ()  ) is the character length of each line, and the contents of the blank line are \ n and two characters. Len is 0 o'clock into the loop;                                                   break        #执行到这里跳出循环;                                           if input in line:     #如果输入的input信息可以匹配到文件的某一行, into the cycle;                                                   print  ' match item: %s '   %line      #输出匹配到的行信息;                                                  match  = 1     #给变量match赋值为1                                   if match == 0 :                #如果match等于0, then enter    ;                                          print   ' no match item found! '           #输出提示信息;         else: print  "sorry ,user  %s not found "  %input        #如果输入的用户不是wenlong, the output information does not have this user;

The above script because adds the note, the direct copy cannot use, here re-paste once;

#!/usr/bin/pythonwhile true:        input = raw_input (' Please input your username: ')         if input  ==  "Wenlong":                 password = raw_input (' Please input your pass: ')                  p =  ' 123 '                  while password !=  p:                         password = raw_input (' please input your  Pass again: ')                  if password == p:                         print  ' welcome to select system! '                          while True:                                  match = 0                                  input = raw_input ("Please input the name whom you  want to search : ")                                  while not  Input.strip ():                                          print  ' no match item found! '                                           input = raw_input ("Please input the name whom you  want to search : ")                                   name_file = file (' Search_name.TXT ')                                  while true:                                           line = name_file.readline ()                                           if len (line)  ==  0:                                                   break                                          if input in  line:                                                  print  ' match  item:  '   , line                                                   match = 1                                 if match == 0 :                                           print  ' no match item found!
