__str__( ):在调用print打印对象时自动调用,是给用户用的,是一个描述对象的方法。 __repr__( ):给机器用的,在Python解释器或者在cmd的黑屏终端里面输入,注意在没有str时,且有repr,str = repr,其实本事就是打印类本身想要实现的属性。 举例说明1: classPerson(object): def __init__(self,name,age,heig...
Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...

This is a guide to Python Overloading. Here we discuss the user-defined and pre-defined functions along with its operator and advantages. You may also look at the following articles to learn more – Python Variables Overloading vs Overriding ...
child class’s implementation is used. Modern programming languages like Java, Eifell, C++ and Python allows method overriding. What is Overloading? Method overloading is a feature provided by some programming languages to create more than one method with the same name, but with different input...
Scope: Overloading is a compile-time concept and occurs within a single class while overriding is a run-time concept and occurs between a superclass and its subclass. Parameters: Overloaded methods must have different parameter lists (different types, different numbers of parameters, or different ...
Method overriding is a concept that occurs in inheritance, where a derived class provides a different implementation for a method that is already defined in its base class. The method in the derived class must have the same name, return type, and parameters as the method in the base class....
Method Overriding: Method Overriding is the method having the same name with the same arguments. It is implemented with inheritance also. It mostly used for memory reducing processes. Learn Python from the Basic to Advanced Level with Hands-on Training, Placements, and more with ...
