任何在模块、类或函数体中以字符串字面量作为第一个声明语句的,都可以被认为是 docstring,通常以三引号分隔: defscale(data,factor):"""Multiply all entries of numeric data list by the given factor.data an instance of any mutable sequence type (such as a list)containing numeric elementsfactor a num...

类与面向对象编程(Object-Oriented Programming, OOP)(一) 对象比较:‘is’ 对比 ‘==’ 当我还是个孩子的时候,我们的邻居拥有一对双胞胎猫咪。它们看起来几乎一模一样—同样的炭黑色毛发和同样锐利的绿色眼睛。尽管有一些性格上的小特点,但只要你从外表上看它们,就很难分辨出它们之间的区别。
Cxx primer-chap15-Object-Oriented Programming 面向对象编程的三个基本概念:数据抽象、继承和动态绑定(多态): 基类应该提供一些类型无关的成员函数定义,将与类相关的函数留给不同的派生类定义:,派生类是通过类派生列表(class derivation list)对基类进行声明:...
Object-oriented programming may be seen as a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a list of instructions to the computer. In OOP, each object is capable of receiving messages, processing data, and sending messages to other ...
Visual Basic 6.0 supports object-oriented language elements and has support for objects distributed in libraries. Visual Basic 2008 extends the support for object-oriented programming by supporting all of its language properties.Conceptual DifferencesThe sections below list object-oriented features in Visual...
template<typename _Tp, typename Compare> inline const _Tp& max(const _Tp& a, const _Tp& b, Compare comp) { return comp(a, b) ? a : b; } 补充两个个知识点: list无法使用公共sort函数的原因是,list的iterator不是random access,前进和后退每次只能移动一个元素。
