python查询接口----运维开发初学

需求：输入用户编号或者用户名，进行查询用户信息，根据编号可以进行精确查询，根据用户名进行模糊查询

思维导图：

#!/usr/bin/env python
#coding:utf-8
import re
import MySQLdb.cursors
conn=MySQLdb.connect(user='root',passwd='123456',host='192.168.2.71',db='login',cursorclass = MySQLdb.cursors.DictCursor)
cur=conn.cursor()
cur.execute("select * from user_account")
user_names=cur.fetchall()

user_list=[]  #用于精确查询
name_list=[]  #以列表的形式保存用户名
for usernum in user_names:
    id_nau = int(usernum['compan_num'])
    user_list.append(id_nau)
    names =usernum['name']
    name_list.append(names)
while True:
    id_nau = raw_input("please input  your's id or account:").strip()
    pattern = ''.join(id_nau)
    regex = re.compile(pattern)
    count_names = [] #进行模糊匹配用户
    for item in name_list:
        match = regex.search(item)
        if match:
            count_names.append(item)

    if len(id_nau) ==0:  #输入不为空
        print "Username cannot be empty!"
        continue
    for id_nau in count_names:
        print "Match Item: %s" % id_nau
        print user_names[name_list.index(id_nau)]
        continue
    try:
        if int(id_nau) in user_list:
            print user_names[user_list.index(int(id_nau))]
            continue
    except:
        continue
