Programming from First Principles Notes

This folder contains a Python-based study guide for the subject Programming from First Principles across Modules 1 to 14. It is written as exam-ready revision notes with one page per module plus supporting revision resources.

Each module follows three learning layers:

1. Simple idea: plain language and a familiar analogy.
2. Worked example: small Python code traced step by step.
3. Technical meaning: correct definitions, notation, types, and exam points.

Finish the memory rules and self-check before reading the answers.

Module-wise study method

1. Review the prerequisites and complete one study block at a time.
2. Type each Python example into the interpreter or notebook and predict the result before running it.
3. Read errors as feedback about syntax, types, or missing definitions.
4. Complete the mini quiz and practice ladder before revealing solutions.
5. Mark the module Mastered after writing and tracing a fresh example unaided.
