Core Python Learning Path

Core Python Learning Path 🐍

This path focuses on mastering Python fundamentals, essential for any Python-based career.

1️⃣ Getting Started with Python

🔹 Install Python & Set Up Environment

• Install Python from python.org
• Use IDLE, VS Code, or PyCharm as an IDE
• Learn about pip (Python Package Installer)

🔹 Basic Syntax & Data Types

• Variables (int, float, str, bool)
• Type Conversion (int(), float(), str())
• Print and Input (print(), input())

📌 Practice: Write a Python script that takes user input and prints it in uppercase.

2️⃣ Control Flow & Loops

🔹 Conditional Statements

• if, elif, else

🔹 Loops

• for and while loops
• Loop control (break, continue, pass)

📌 Practice: Write a program to check if a number is prime.

3️⃣ Data Structures in Python

🔹 Lists

• Indexing, Slicing, List Methods (append(), remove(), sort())

🔹 Tuples

• Immutable sequences

🔹 Dictionaries

• Key-Value pairs (dict, .get(), .keys())

🔹 Sets

• Unique elements (set, .add(), .union())

📌 Practice: Create a dictionary storing student names and marks, and fetch details by user input.

4️⃣ Functions & Modules

🔹 Functions

• Defining & Calling functions (def, return)
• Function Arguments (positional, keyword, default, *args, **kwargs)

🔹 Modules & Packages

• Importing modules (import math, from random import randint)
• Creating custom modules

📌 Practice: Write a function to calculate the factorial of a number using recursion.

5️⃣ File Handling

🔹 Reading & Writing Files

• open(), read(), write(), close()
• Working with csv and json files

📌 Practice: Create a program that reads a file, counts the number of words, and writes the count to another file.

6️⃣ Exception Handling

🔹 Handling Errors

• try, except, finally
• Raising Exceptions (raise ValueError)

📌 Practice: Write a program that handles division by zero errors gracefully.

7️⃣ Object-Oriented Programming (OOP)

🔹 Classes & Objects

• Defining a class, creating objects
• __init__() constructor

🔹 Encapsulation, Inheritance & Polymorphism

• Private & Public attributes
• Parent-child class relationships

📌 Practice: Build a Car class with attributes and methods like start(), stop().

8️⃣ Advanced Python Concepts

🔹 Lambda Functions

• Anonymous functions (lambda x: x * 2)

🔹 List Comprehensions

• [x**2 for x in range(10)]

🔹 Decorators & Generators

• @decorator, yield

📌 Practice: Create a generator function that yields Fibonacci numbers.

9️⃣ Working with APIs

🔹 Making HTTP Requests

• requests module (GET, POST)

🔹 Handling JSON Data

• json.loads() & json.dumps()

📌 Practice: Fetch and display weather data from an API.

🔟 Next Steps

• Practice projects (To-Do List, Calculator, Web Scraper)
• Learn a framework (Flask, Django, FastAPI)
• Work on coding challenges (LeetCode, HackerRank)
