本文实例讲述了python操作sqlite的CRUD实现方法。分享给大家供大家参考。具体如下：
import sqlite3 as dbconn = db.connect('mytest.db')cursor = conn.cursor()cursor.execute("drop table if exists datecounts")cursor.execute("create table datecounts(date text, count int)")cursor.execute('insert into datecounts values("12/1/2011",35)')cursor.execute('insert into datecounts values("12/2/2011",42)')cursor.execute('insert into datecounts values("12/3/2011",38)')cursor.execute('insert into datecounts values("12/4/2011",41)')cursor.execute('insert into datecounts values("12/5/2011",40)')cursor.execute('insert into datecounts values("12/6/2011",28)')cursor.execute('insert into datecounts values("12/7/2011",45)')conn.row_factory = db.<span style="color:transparent">来1源gaodai#ma#com搞*代#码1网</span>Rowcursor.execute("select * from datecounts")rows = cursor.fetchall()for row in rows: print("%s %s" % (row[0], row[1]))cursor.execute("select avg(count) from datecounts")row = cursor.fetchone()print("The average count for the week was %s" % row[0])cursor.execute("delete from datecounts where count = 40")cursor.execute("select * from datecounts")rows = cursor.fetchall()for row in rows: print("%s %s" % (row[0], row[1]))
希望本文所述对大家的Python程序设计有所帮助。
