Variables and Constants in Python | Python Basics for Academics and Research

Описание: In this video, we’re going to talk about one of the most basic but powerful concepts in Python — variables and constants.
If you’re just starting your Python journey for academics or research, understanding these two is the first real step toward writing meaningful code.

A variable is simply a name that stores some data — it could be a number, a string, or even experimental data from your research.
A constant is a value that never changes, like the speed of light or the value of π in a physics project.
Knowing when and how to use them will make your code cleaner, easier to understand, and more useful in your academic work.

In this lesson, I’ll explain:

What variables and constants are in simple terms

How to create them in Python

Naming rules and good practices

Examples you can actually relate to from science and research

A few common mistakes beginners make and how to avoid them

By the end of this video, you’ll not only know how variables and constants work, but also how they fit into bigger programs you’ll build later in this playlist — like handling data, analyzing experiments, or plotting graphs.
