Python

Introduction to Python — Your first steps into Python programming. Learn what Python is, how to install it, and write your very first program.
Variables and Data Types — Learn about Python variables and data types — strings, integers, floats, booleans, and how to work with them.
Control Flow: If, Else, Loops — Make your programs smart with conditional logic (if/elif/else) and loops (for, while) in Python.
Functions and Modules — Write reusable functions, understand parameters and return values, and organize code with modules.
Lists, Tuples, and Dictionaries — Master Python's essential data structures for managing collections of data efficiently.
String Methods and Formatting — Master Python string methods — split, join, replace, strip, find — and advanced f-string formatting.
Reading and Writing Files — Learn to read and write files in Python — text files, CSV, file paths, and the with statement.
Error Handling with Try/Except — Build robust programs that handle errors gracefully with try/except, raise, and custom exceptions.

Inheritance and Polymorphism — Build class hierarchies, override methods, use super(), and understand composition vs inheritance.
Working with JSON Data — Read, write, and manipulate JSON data for APIs, config files, and data exchange between systems.
Regular Expressions — Match patterns, extract data, and validate input with Python's powerful re module.
Virtual Environments and Packages — Manage Python packages with pip and isolate project dependencies with virtual environments.
