python连接数据库批量插入数据

 1 思路：连接数据库-获取游标-拼好sql-执行sql-提交数据-关闭游标-关闭链接
 2 import MySQLdb,time,pprint
 3 import random
 4 t = int(time.time())
 5 #链接数据库
 6 connection = MySQLdb.connect(host="127.0.0.1",
 7                      user="songqin",
 8                      passwd='songqin',
 9                      db='plesson',
10                      charset = "utf8")
11 #获取游标
12 c = connection.cursor()
13 sql = "select * from sq_course"
14 for i in range(1,11):
15     names = random.choice(['语文','数学','外语','物理','化学'])+str(i)
16     descs = "课程描述"+str(i)
17     idx = str(i)
18     sql1 = "INSERT INTO sq_course (name,`desc`,display_idx) VALUES('%s','%s','%s');" %(names,descs,idx)
19     #执行SQL
20     raw = c.execute(sql1)
21     #插入数据完后提交数据
22     connection.commit()
23  
24 raw1 = c.execute(sql)
25 pprint.pprint(c.fetchall())
26 #关闭游标
27 c.close()
28 #连接关闭
29 connection.close()
