python之如何获得整数的加法对象

在Python中有什么方法可以在Python中获取整数的加法对象(运算符+)并将其存储在某个地方吗？

请您参考如下方法:

>>> int_add = int.__add__ 
>>> int_add(1, 2) 
3 

您还可以使用 operator.add获取用于在 Python 中添加的通用函数:

>>> from operator import add 
>>> add(1, 2) 
3 
>>> add('a', 'b') 
'ab' 

如果想获取特定整数的加法方法，而不是int类型，请看gnibbler对问题的评论:

To get the bound add method of an integer you should use parentheses to prevent the . being treated as a decimal point. eg (1).__add__. Another way would be to add a space between the 1 and the . eg 1 .__add__ but I think that it is too obscure.

一个例子:

>>> one_add = 1 .__add__ 
>>> one_add(2) 
3
