Python operates on the database

import pymysql
#连接数据库
conn = pymysql.connect(
  host='localhost',
  port=3306,
  user='root',
  passwd='123456',
  db='qq绑',
  charset='utf8',
)
cursor = conn.cursor()
for i in range(6,84):
 
  
  f = open('D:\BaiduNetdiskDownload\ll\QB ('+str(i)+').txt', "r",encoding = 'utf-8')
  while True:
#逐行读取
   line = f.readline()
   if line :

    list=line.split('----')
    phone=list[0]
    qqnumber=list[1]
  
    cursor.execute(
                    'insert into qq绑  values("{0}","{1}" )'.format(phone,qqnumber)
                  )   
    
   else:
    break
  f.close()

cursor.close()
conn.commit()
conn.close()
print("ok")
