Python Basic

A self-paced Python course for beginners, with a strong focus on clear fundamentals and problem solving.

This course is written for a first-time programmer, including school students. You do not need to know Java, mathematics beyond school level, or any programming language before you begin.

This course is written from scratch for Python 3, with simple explanations, practical examples, and deliberate problem-solving practice.

If you feel stuck

That is normal. Use this order:

1. Re-read the example and type it yourself.
2. Change one small value and run it again.
3. Read the error message and note its line number.
4. Open the lesson's Common mistakes section.
5. Try one problem from the lesson's Practice section.
6. Open one hint only after making your own attempt.
7. Return to the Learning Guide and use the problem-solving worksheet.

What you will build

• Small programs from the first lesson
• A calculator and bill generator
• A marks analyzer and contact book
• A file-based expense tracker
• A student management system

Course principles

• Small explanations, line-by-line examples, and expected output.
• Important Python behavior stated clearly, including surprising rules.
• Beginner Bug Hunter exercises that make debugging normal and enjoyable.
• At least ten problems for every major topic.
• Hints and solutions kept separate from the problem statement.
• Regular debugging, output prediction, and interview-style practice.
• No assumed tutor support: prerequisites, mistakes, and next steps are documented.

Repository layout

• 00-setup/ - installation and environment setup
• Numbered folders - lessons in learning order
• problem-solving/ - optional standalone archive of topic-wise exercises, hints, and solutions
• interview-problems/ - mixed interview-oriented practice
• projects/ - guided applications
• quizzes/ - checkpoints and final assessment
• glossary/ - quick reference for important terms

The main learning path keeps practice inside each lesson. Hints and solution ideas are hidden in collapsed sections so a beginner can stay on one page and reveal help only when needed.
