Python

Introduction

This repo covers Python fundamentals, OOP, DSA, multithreading, exception handling, file I/O, and key libraries like collections and itertools. It includes real-world projects and coding challenges (LeetCode, HackerRank).

Topics Covered

Python Fundamentals

• Variables, data types, and operators
• Control flow (if-else, loops)
• Functions and scope
• Built-in functions and modules

Object-Oriented Programming (OOP)

• Classes and objects
• Inheritance and polymorphism
• Encapsulation and abstraction
• Special methods (init, str, etc.)

Data Structures & Algorithms (DSA)

• Arrays, Linked Lists, Stacks, Queues
• Trees, Graphs, Heaps, Hash Tables
• Sorting and Searching algorithms
• Recursion and Dynamic Programming

Multithreading

• Thread creation and management
• Thread synchronization and locks
• Use cases and performance considerations

Exception Handling

• Try, except, finally
• Raising custom exceptions
• Best practices for error handling

File I/O

• Reading and writing files
• Working with different file formats (.txt, .csv, .json)
• Context managers

Standard Libraries

• collections (Counter, defaultdict, deque, etc.)
• itertools (combinations, permutations, groupby, etc.)
