BASICS OF PYTHON PROGRAMMING

What is Programming?
Programming is the art of communicating with a computer by giving it a
clear set of instructions to perform a specific task. These instructions are
written in the form of programs, which tell the computer what to do, how to
do it, and when to do it.
Programming involves:
Designing the solution
Writing the code
Testing the program
Fixing errors (debugging)
Through programming, we can create software such as mobile apps,
websites, games, banking systems, artificial intelligence programs, and
much more.

What is a Programming Language?
A programming language is a special language used to write instructions
that a computer can understand and execute. It acts as a bridge between
humans and machines, allowing developers to express ideas in a
structured format.
Some popular programming languages include:

Language Usage

Python Web development, data science, AI, ML

Java Android apps, enterprise systems

JavaScript Websites and web apps

C/C++ System programming, games

PHP Web server scripting

R Data analysis

SQL Database management
