Pythonfile object provides methods and attributes to access and manipulate files. Using file objects, we can read or write any files. Whenever weopen a fileto perform any operations on it, Python returns a file object. To create a file object in Python use the built-in functions, such aso...

Python从设计之初就已经是一门面向对象的语言,正因为如此,在Python中创建一个类和对象是很容易的。本章节我们将详细介绍Python的面向对象编程。 如果你以前没有接触过面向对象的编程语言,那你可能需要先了解一些面向对象语言的一些基本特征,在头脑里头形成一个基本的面向对象的概念,这样有助于你更容易的学习Python的面...

静态方法Static Methods 静态方法这个特性我写到现在从没用上过,说实话感觉有点鸡肋。静态方法不与类实例绑定,而是属于一个类。所以他不需要self参数来做指引。 一般来说,我唯一能想到静态方法的使用场景就是写一些utility function,来看个例子: class Pizza(object): @staticmethod def mix_ingredients(x, y): retu...

创建新类:通过定义一个类,你创建了一个新的对象类型(type of object)。这意味着你可以创建该类的多个实例,每个实例都是类的一个具体化,拥有类定义的属性(attributes)和方法(methods)。 实例化:创建类的实例的过程称为实例化(instances)。每个实例都拥有自己的属性值,但共享类定义的方法。
