Overloading Comparison Operators Python does not limit operator overloading to arithmetic operators. We can overload comparison operators as well. Here's an example of how we can overload the<operator to compare two objects of thePersonclass based on theirage: classPerson:def__init__(self, n...
Each operator can be used in a different way for different types of operands. For example,+operator is used foradding two integersto give an integer as a result but when we use it withfloat operands, then the result is a float value and when+is used withstring operands 每个运算符可以以...
一、运算符重载运算符重载(Operator Overloading):让一个运算符可以有不同的功能。已经熟知的运算符重载,如‘+’,可以对不同类型的(int,float)的数据进行加法操作;'<<’既是位移运算符,又可以配合 cout 向控制台输出数据。C++允许程序员自己重载运算符。以下代码定义了一个复数类,通过运算符重载,可以用+号实现...

I started working on creating a number class that behaves like an int but is represented as an n-base number. Here's how I proceeded: I built a metaclass to collect method names that are exclusively part of the int type. I used these names to wrap the int special metho...
overloading is the process of extending the predefined function of an operator to user defined functions. For example, the operator + is used to add two integers, join two strings, and merge two lists. The operator '+' is used for multiple purposes and is thus called operator overloading...

我们知道Python中有+、-等数学操作符号,那么这些操作是怎么定义和实现的呢?我们称这种方法为运算符重载(operator overloading),实现的具体过程是通过一些特殊命名的方法(Specially named method)。例如最简单的加法: “+”这个操作具体实现过程实际上是通过一个__add__的方法定义的。我们知道int其实是一个类(class)...
您可以根据所使用的操作数来更改Python中运算符的含义。 这种做法称为运算符过载。 什么是Python中的运算符重载? Python运算符用于内置类。但是相同的运算符对不同的类型有不同的行为。例如,+运算符将对两个数字执行算术加法、合并两个列表并连接两个字符串。
If the behavior of a built-in function or operator is not defined in the class by the special method, then you will get a TypeError.So, how can you use special methods in your classes?Overloading Built-in Functions Many of the special methods defined in the Data Model can be used to...
