These methods have their names sandwiched by two underscores on either side. Let’s have a look at an example. Constructor Initializer: __init__ If you’ve done Object Oriented Programming (OOP) in Python, you’re…

Lean in and embrace the chance to learn and get better. — Disagreements are a natural part of being a software engineer.

Polymorphism is a pillar of Object Oriented Programming. OOP underpins modern software development in many industries. This article will dive in to Polymorphism by using a real world non-contrived example. That’s right: Polymorphism will not be explained in terms of animals or Dogs or Ducks but in terms of a…
