本文实例讲述了Python运算符重载用法。分享给大家供大家参考。具体分析如下：

python中，我们在定义类的时候，可以通过实现一些函数来实现重载运算符。

例子如下：

# -*- coding:utf-8 -*- 
''''' 
Created on 2013-3-21 
@author: naughty 
''' 
class Test(object): 
  def __init__(self, value): 
    self.value = value 
  def __add__(self, x): 
    return self.value + x.value 
a = Test(3) 
b = Test(4) 
print a + b
Copy after login

运行结果为：7

上面我们重载了加法。其他类似。

希望本文所述对大家的Python程序设计有所帮助。
