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...
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, name, age):self.name = name ...

operator模块中的函数通过标准 Python 接口进行操作,因此它可以使用用户定义的类以及内置类型。 from operator import * class MyObj: """Example for operator overloading""" def __init__(self, val): super(MyObj, self).__init__() self.val = val ...
class MulOperator: def __init__(self,a,b): self.a=a self.b=b def __mul__(self,n): return MulOperator(self.a*n,self.b*n) i=MulOperator(20,5) j=i*4.5 print j.a,j.b 重载乘法:两个对象的相乘似乎也有用,如矩阵的相乘,3D中几个变换矩阵的相乘。
Operator overloading is an essential process in OOP, which adds multiple functions to the available operators. Operator 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 st...

Operator overloading(操作符重载) Python支持操作符重载。“操作符重载”其实是个简单的概念,你是否曾经想过为什么Python可以让你使用“+”操作符来同时实现加法和连接字符串?这就是操作符重载在发挥作用。 你可以定义使用Python标准操作符符号的对象,这可以让你在特定的环境中使用特定的对象,就像下方的例子一样。 pp...
