Python Operator Overloads	2020-03-13T20:49:28-04:00	false	Python

I wrote a blog post about operator overloads in C++. Luckily for Python it is heavily document in what is called the Python Data Model. Though for the sake of having content, I'll share some of the ones that I heavily use in my classes.

Operator	Method
+	__add__(self, other)
==	__eq__(self, other)
len()	__len__(self)
str()	__str__(self)
hash()	__hash__(self)

Example Usage:

class Test:
	def __init__(self, x):
        self.x = x
    def __add__(self, other):
        return Test(self.x, other.x)
    def __eq__(self, other):
        return self.x == other.x
    def __len__(self):
        return len(self.x)
    def __str__(self):
        return self.x
    def __hash__(self):
        return hash(self.x)
