1.在执行await cur.execute(sql, args)时，报错AttributeError: 'builtin_function_or_method' object has no attribute 'translate'

这里的代码是根据廖雪峰的python教程写的实战代码，在进行用户注册功能测试执行保存时报错

2.代码

async def execute(sql,args,autocommit=True):
    log(sql)
    async with __pool.get() as conn:
        if not autocommit: # 如果不是自动提交
            await conn.begin()
        try:
            async with conn.cursor(aiomysql.DictCursor) as cur:
                sql = sql.replace('?', '%s')
                await cur.execute(sql, args)
                affected = cur.rowcount # 获取sql语句影响的行数
            if not autocommit:
                await conn.commit()
        except BaseException as e:
            print('e: ',e)
            if not autocommit:
                await conn.rollback()
            raise
        return affected
