▬▬▬▬ 📖 Content ▬▬▬▬

🖥️ You might have produced a “Hello, World!” program, in your chosen programming language. It is all very well, but quite limited, right?!

More complex programs need a way of labelling data with a name, so it can then be referenced later. This has the rather wonderful side-effect of making computer code easier to read!

Nonetheless, there are a certain rules we have to follow, while declaring a variable. Let's take a look at the variable definition, to understand how we declare a variable then how access it, in Python.

In a programming language, a variable is a memory location, that has a name attached to its particular object. Variables are like containers. The value that you have stored into this container may change in the future, according to the specifications.

🎯 What are variables? How to declare and access a variable? What syntax should you stick with, and What are the reserved keywords? What is the scope of a variable? What are the Data Types of a variable?

Let's play this video, stick around and watch until the end! 👍🏻
