This article will explain in detail how to implement the comparison operator in python. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Implement the comparison operator

If we were to implement all the comparison operators for a class one by one, you would find it troublesome, because there are a lot of methods to implement, such as _ _ lt__,__le__,__gt__, and _ _ ge__.

In fact, Python provides a convenient way to implement it through the functools.total_ordering decorator.

From functools import total_ordering @ total_ordering classNumber: def _ _ init__ (self, value): self.value = value def _ lt__ (self, other): returnself.value

Number (3)) print (Number (1)

= Number (15)) print (Number (10)
