面向对象编程(Object-oriented Programming,简称 OOP),是一种封装代码的方法。其实,在前面章节的学习中,我们已经接触了封装,比如说,将乱七八糟的数据扔进列表中,这就是一种简单的封装,是数据层面的封装;把常用的代码块打包成一个函数,这也是一种封装,是语句层面的封装。面向对象编程,也是一种封装的思想,不过显然比以上两种封装更
Methods are functions defined inside the body of a class. They are used to perform operations with the attributes of our objects. Methods are essential in theencapsulationconcept of the OOP paradigm. For example, we might have aconnectmethod in ourAccessDatabaseclass. We need not to be informe...
First I will say I loved this Python 3 tutorial, right up to the OOP module. At this point it seems to barely explain anything. At the magic-methods I am completely lost. Should I have taken a prerequisite to Python in order to understand the Python OOP module? --- Please don't ans...

OOP 是一种范例,其中程序数据被分成混合的对象和函数或方法。对象是一种数据类型——通常是其他数据类型的集合,如整数、字符串等等。对象通常是类的一部分,这些类有关联的方法可以作用于该类的成员。也许说明这一点最简单的方法是用一个使用形状的例子。在这个例子中,形状是一类对象。那个类有相关的值,比如name和...
