本文实例讲述了Python基类函数的重载与调用方法。分享给大家供大家参考。具体分析如下:
刚接触Python语言的时间不长,对于这个语言的很多特性并不是很了解,有很多用法都是还不知道。今天想着写一个Python面向对象编程时的继承中的函数调用。分享出来,一起进步。
因为之前接触过Java和C++,所有对于面向对象的思想也早已经很熟析的了。这里也不再对面向对象是什么进行赘述了。我们直接上代码吧!看看对于继承和基类函数的调用在Python中是如何调用的~
首先,是基类文件base.py

'''
class animal(object):
'''
classdocs
'''
def __init__(self):
'''
Constructor
'''
print 'animal init'
def say(self):
print 'animal say'
然后,是子类文件child.py

'''
from inheritance.base import animal
class cat(animal):
'''
classdocs
'''
def __init__(self):
'''
Constructor
'''
# animal.__init__()
animal.__init__(self)
print 'cat init'
def say(self):
animal.say(self)
print 'cat say'
if __name__ == '__main__':
c = cat()
c.say()
运行后,就可以看到输出,如下:
animal init
cat init
animal say
cat say
这就说明,我们的继承和函数的调用都已经OK了
此例子比较简单,不过基本上也讲明白了Python基类函数的重载与调用,希望学习的同学可以举一反三。
希望本文所述对大家的Python程序设计有所帮助。

Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

Python is widely used in the fields of web development, data science, machine learning, automation and scripting. 1) In web development, Django and Flask frameworks simplify the development process. 2) In the fields of data science and machine learning, NumPy, Pandas, Scikit-learn and TensorFlow libraries provide strong support. 3) In terms of automation and scripting, Python is suitable for tasks such as automated testing and system management.

You can learn the basics of Python within two hours. 1. Learn variables and data types, 2. Master control structures such as if statements and loops, 3. Understand the definition and use of functions. These will help you start writing simple Python programs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
