🐍 Python Daily Projects

Small, working Python programs — built by hand first, then rebuilt with AI to compare

📖 About

A growing archive of practical Python mini-projects — one folder per project, each focused on a core concept (input validation, control flow, functions, dictionaries, unit conversion…).

The twist: every project has two versions.

Version	How it's built	Purpose
🖐️ Manual	Written independently, from scratch	Prove I can solve it myself
🤖 AI-assisted	Same problem, rebuilt with Claude's help	Compare structure, naming, error-handling and best practices — then learn from the gap

Both versions ship as a Jupyter notebook and a PDF export so the code and its output are readable without running anything.

📌 Projects

#	Project	What it does	Concepts	Files
1	Motion Calculator	CLI tool that calculates Speed, Distance or Time from the other two, with 7 distance units and 7 speed units	input() validation loops · try/except · if/elif chains vs dict lookups · unit-conversion maths · f-string formatting	Manual .ipynb + .pdf · AI .ipynb + .pdf

New projects are added as they're built — check the folders for the latest.

🔍 Project 1 — Motion Calculator

=============================================
           MOTION CALCULATOR MENU
=============================================
   [1] Speed
   [2] Distance
   [3] Time
---------------------------------------------
Enter What you want to Calculate : speed
Available units for Distance: Inch, Feet, Yard, Mile, CM, Meter, KM
Choose Unit of Distance: mile
Enter Distance in mile: 26.2
Enter the time in Minutes: 180
Available units for Speed: KM/H, Mph, Feet/s, Inch/s, Yards/m, Meter/s, CM/s
Enter the unit of speed you want to see: mph

Speed is: 8.73 Mph

Supported units

Distance	Speed
inch · feet · yard · mile · cm · meter · km	km/h · mph · ft/s · in/s · yd/min · m/s · cm/s

All maths is done in a common base (km and km/h) and converted to/from the user's chosen units.

Manual vs AI — what I learned

Aspect	🖐️ Manual version (212 lines)	🤖 AI version (210 lines)
Structure	One top-level script, three big if/elif blocks	12 small functions + main() entry point
Unit conversion	Repeated if/elif ladders per unit	Two lookup dicts (DISTANCE_TO_KM, SPEED_FROM_KMH) + alias maps
Input validation	valid_num() helper re-asks on bad numbers	Same idea, plus allow_zero flag and validated menu choice
Unit aliases	Partial (ft, m, kmh)	Full (inches, kilometers, yd/min …)
Re-use	Hard to extend — new unit = 6 edits	New unit = 1 dict entry

Takeaway: a dictionary lookup beats an if/elif chain the moment you have more than ~3 cases; and splitting a script into functions makes it testable and extendable. The next project applies both from the start.

🚀 How to run

git clone https://github.com/Mohammadshadab1/python-daily-projects.git
cd "python-daily-projects/Motion Calculator"
jupyter notebook          # open either .ipynb and Run All

No external libraries — only the Python standard library.

🎯 Purpose

• Practise core Python daily with small, real, finished programs
• Learn better patterns by comparing my code with an AI-assisted version
• Build a public log of consistent coding practice
