本文实例讲述了Python简单操作sqlite3的方法。分享给大家供大家参考，具体如下：

									import sqlite3

									def Test1():

									  #con =sqlite3.connect("D:\\test.db")

									  con =sqlite3.connect(":memory:") #store in memory

									  cur =con.cursor()

									  try:

									    cur.execute('create table score(id integer primary key,name varchar(10),scores integer)')

									    cur.execute("insert into score values(0,'Rose',87)")

									    cur.execute("insert into score values(1,'Alice',78)")

									    cur.execute("insert into score values(2,'Helon',100)")

									    cur.execute("insert into score values(3,'Tom',98)")

									    cur.execute("insert into score values(4,'jack',198)")

									    cur.execute("insert into score values(5,'Tony',198)")

									    cur.execute("insert into score values(6,'David',99)")

									    cur.execute("update score set scores =? where id=?",(45,3))

									    cur.execute("update score set name=? where id=?",("John",0))

									    cur.execute("delete from score where id =1")

									  except Exception,e:

									    print "There are some except",e

									  con.commit()

									  print "Insert Complete"

									  print "-----------------------------------------"

									  print "Last row id is ",cur.lastrowid

									  cur.execute('select * from score')

									  print cur.fetchall()

									  print "----------------------------------------"

									  cur.execute("select count(*) from score")

									  print "Current Rows is :",cur.fetchall()[0]

									  cur.close()

									  con.close()

									if __name__ =='__main__':

									  Test1()

									  print "hello world"
