cur = con.cursor()
#创建表staffcur.execute(drp_tb_sql)cur.execute(crt_tb_sql)#插入记录insert_sql = "insert into staff (name,city) values (?,?)" #?为占位符
cur.execute(insert_sql,('Tom','New York'))

cur.execute(insert_sql,('Thomas','Houston'))
cur.execute(insert_sql,('Sam','Philadelphia'))
con.commit()#查询记录select_sql = "select * from staff"
cur.execute(select_sql)#返回一个list，list中的对象类型为tuple（元组）date_set = cur.fetchall()
