使用python将mysql的查询数据导出到文件

import mysql.connector 
cnx = mysql.connector.connect(user='scott', password='tiger', 
 host='127.0.0.1', 
 database='employees') 
cnx.close()

import datetime 
import mysql.connector 
cnx = mysql.connector.connect(user='scott', database='employees') 
cursor = cnx.cursor() 
query = ("SELECT first_name, last_name, hire_date FROM employees " 
 "WHERE hire_date BETWEEN %s AND %s") 
hire_start = datetime.date(1999, 1, 1) 
hire_end = datetime.date(1999, 12, 31) 
cursor.execute(query, (hire_start, hire_end)) 
for (first_name, last_name, hire_date) in cursor: 
 print("{}, {} was hired on {:%d %b %Y}".format( 
 last_name, first_name, hire_date)) 
cursor.close() 
cnx.close()

import time 
filename = 'page_list_'+str(time.strftime("%Y%m%d"))+'.txt' 
output = open(filename,'w') 
output.write(str(page_title).lstrip('(b'').rstrip('',)')+"
") 
output.close()
