Learn Python in 30 Days: A Practical Roadmap

A day-by-day plan with weekly projects, OOP milestones, and interview prep to take you from zero to job-ready Python fundamentals.

Week 1: Foundations (Days 1–7)

Days 1–2: Install Python, learn variables, data types, and basic I/O. Write scripts that convert temperatures and calculate compound interest. Days 3–4: Conditionals, loops, and functions. Build a number guessing game and a simple grade calculator.

Days 5–7: Lists, dictionaries, and file handling. Project: parse a CSV of expenses and print a summary by category. Use Rishtaara's Python compiler daily — typing code beats reading about it.

Week 2: Intermediate Python (Days 8–14)

Learn list comprehensions, error handling with try/except, and modules. Read the official docs for at least one standard library module (datetime or json).

Project: build a command-line contact book that saves to JSON. Add search, delete, and input validation. This single project reinforces half of beginner Python.

Week 3: Object-Oriented Programming (Days 15–21)

Classes, inheritance, and dunder methods. Refactor your contact book into a class-based design. Learn pip and virtual environments so dependencies stay isolated per project.

Mini-project: simulate a bank account with deposit, withdraw, and transaction history. Focus on clear method names and preventing invalid states (negative balances).

Week 4: Job-Ready Skills (Days 22–30)

Pick one direction: web (Flask basics), data (pandas introduction), or automation (scripting + APIs). Build one portfolio project end-to-end with a README explaining setup and design decisions.

Days 28–30: solve 20 Python MCQs and 10 interview questions under timed conditions. Document mistakes in a cheat sheet. This mirrors how hiring screens actually feel.

Key Takeaways

One project per week beats passive video consumption.
Use virtual environments from week 3 onward — it is a professional habit.
End the month with a portfolio piece plus timed practice questions.
After 30 days, expect solid beginner level — not senior developer status.

Frequently Asked Questions

Is 30 days enough to get a Python job?: Thirty days can build a strong beginner foundation. Most entry-level roles expect additional months of project work, CS fundamentals, and interview preparation.
