如果需要频繁的更新、删除操作的数据库,也可以选择InnoDB,因为支持事务的提交 (commit) 和回滚 (rollback)。 MEMORY MEMORY使用存储在内存中的内容来创建表,而且数据全部放在内存中。每个基于MEMORY存储引擎的表实际对应一个磁盘文件。该文件中只存储表的结构。而其数据文件,都是存储在内存中,这样有利于数据的快速处理...

一、python有自动垃圾回收机制(当对象的引用计数为零时解释器会自动释放内存),出现内存泄露的场景一般是扩展库内存泄露或者循环引用(还有一种是全局容器里的对象没有删除) 前者无需讨论,后者举例如下(Obj('B')和Obj('C')的内存没有回收)(貌似循环引用的内存,Python解释器也会自己回收(标记-清除垃圾收集机制),只是...
简介:本文包括python基本知识:简单数据结构,数据结构类型(可变:列表,字典,集合,不可变:数值类型,字符串,元组),分支循环和控制流程,类和函数,文件处理和异常等等。 Python基础知识点总结 一、开发环境搭建 二、基本语法元素 2.1 程序的格式框架 程序的格式框架,即段落格式,是Python语法的一部分,可以提高代码的...
developers were responsible for all memory management in their programs. This meant before creating a list or an object, you first needed to allocate the memory for your variable. After you were done with your variable, you then needed to deallocate it to “free” that memory for other users...
