Python简单查询用户一,第一种: 采用文件中contact.txt中第一行读出后,将其分割成列表,然后对其判断,但是不支持部门查询。 #!/usr/bin/env python while True: name=raw_input("please input name:") if name == "small": while True: password=raw_input("please input password:") if password == "123": print "welcome login system" while True: input=raw_input("please input employee name:") f=open("contact.txt","r") match=0 for i in f.readlines(): if input == i.split(" ")[1]: print i match=1 if match==0: print "user not found,please input" f.close() #break else: print "password is wrong,try again" break第二种:将文件中每行读出后成字符串的形式,因此支持各个字段查询。 #!/usr/bin/python while True: input = raw_input("please input your username:") if input == "small": password = raw_input("please input your pass:") p = "123" while password != p: password = raw_input("wrong passwd,input again:") else: print "welcome login to linux!" while True: match_yes = 0 input = raw_input(" 33[32mPlease input name whom you want to search:33[0m") contact_file = file("contact_list.txt","r") while True: line = contact_file.readline() if len(line) == 0:break if input != "" and input in line: print "match item: 33{36,1m%s 33[0m" % line match_yes = 1 if match_yes == 0 :print "no match item found"第三种:用字典的方式来实现 #!/usr/bin/env python f=file("contact.txt") personal={} for line in f.readlines(): name= line.split()[0] personal[name]=line while True: f=file("contact.txt") personal={} for line in f.readlines(): name= line.split()[0] personal[name]=line while True: input=raw_input("please input username:").strip() if len(input) == 0:continue if input in personal: #if personal.has_key(input): #print "username information: %s" %personal.get(input) print "username information: %s" %personal[input] else: print "%s not found,please input" %inputPython 的详细介绍:请点这里 Python 的下载地址:请点这里推荐阅读:《Python开发技术详解》.( 周伟,宗杰).[高清PDF扫描版+随书视频+代码] http://www.linuxidc.com/Linux/2013-11/92693.htmPython脚本获取Linux系统信息 http://www.linuxidc.com/Linux/2013-08/88531.htm
