import sqlite3

#查询
def load(table):
    #连接数据库
    con = sqlite3.connect("E:/Datebase/SQLiteStudio/Park.db")
     #获得游标
    cur = con.cursor()
    #查询整个表
    cur.execute(‘select *from ‘+table)
    lists = [‘name‘,‘password‘]
    if table == ‘login‘:
        #将数据库列名存入字典
        colnames = {desc[0] for desc in cur.description}
        将字典和数据库的数据一起存入列表，获得了记录字典
        rowdicts = [dict(zip(lists, row)) for row in cur.fetchall()]
    else:
        rowdicts = []
        for row in cur:
            rowdicts.append(row)
    con.commit()
    cur.close()
    return rowdicts

#插入数据
def insert_data(ID,name,money):
    con = sqlite3.connect("E:/Datebase/SQLiteStudio/Park.db")
    cur = con.cursor()
    #使用SQL语句插入
    cur.execute(‘insert into Charge values (?,?,?)‘, (ID,name, money))
    #插入后进行整表查询，看是否成功插入
    cur.execute(‘select *from Charge‘)
    print(cur.fetchall())
    con.commit()
    cur.close()
