python連接數據庫批量插入數據

思路：連接數據庫-獲取游標-拼好sql-執行sql-提交數據-關閉游標-關閉鏈接
import MySQLdb,time,pprint
import random
t = int(time.time())
#鏈接數據庫
connection = MySQLdb.connect(host="127.0.0.1",
                     user="songqin",
                     passwd='songqin',
                     db='plesson',
                     charset = "utf8")
#獲取游標
c = connection.cursor()
sql = "select * from sq_course"
for i in range(1,11):
    names = random.choice(['語文','數學','外語','物理','化學'])+str(i)
    descs = "課程描述"+str(i)
    idx = str(i)
    sql1 = "INSERT INTO sq_course (name,`desc`,display_idx) VALUES('%s','%s','%s');" %(names,descs,idx)
    #執行SQL
    raw = c.execute(sql1)
    #插入數據完后提交數據
    connection.commit()
 
raw1 = c.execute(sql)
pprint.pprint(c.fetchall())
#關閉游標
c.close()
#連接關閉
connection.close()
