This repository contains Python programs that you will explore using the PRIMM methodology (Predict, Run, Investigate, Modify, Make). Each program corresponds to a flowchart and demonstrates key programming concepts.
| Program | Concept | Description |
|---|---|---|
01netflix_binge_sequence.py |
Sequence | Calculate binge-watching time |
02gaming_achievement_selection.py |
Selection | Determine gaming achievements |
03spotify_playlist_iteration.py |
Iteration | Analyse playlist moods |
04social_media_mixed.py |
Mixed Concepts | Social media engagement |
05food_delivery_mixed.py |
Mixed Concepts | Food delivery calculator |
Before running each program:
- Study the corresponding flowchart in the
flowcharts/folder - Read through the Python code
- Predict what will happen when you run it with these inputs:
Program 1 (Netflix):
- Series: "Stranger Things"
- Episodes per season: 8
- Seasons: 4
- Episode length: 50 minutes
Program 2 (Gaming):
- Score: 12000
- Hours played: 60
- Enemies defeated: 800
Program 3 (Spotify):
- Playlist: "My Vibes"
- Songs: 5
- Moods: happy, sad, energetic, happy, chill
Run each program and check your predictions:
python 01netflix_binge_sequence.py
python 02gaming_achievement_selection.py
python 03spotify_playlist_iteration.pyAnswer these questions after running:
Program 1:
- How does the program calculate total hours?
- What happens if you enter 0 seasons?
Program 2:
- Which condition is checked first in the if-elif chain?
- What achievement would you get with score=6000, hours=15, enemies=500?
Program 3:
- How does the counter system work?
- What determines the "Overall mood"?
📢 Friendly message. 📢 If you have limited programming experience, some of the following tasks might seem hard at this moment in time. Don't worry! Pick and choose!
Make these changes:
Program 1:
- Add a calculation for "episodes per day" if watched over a week
- Include a warning if total days > 7
Program 2:
- Add a new achievement level: "Legend" (score ≥ 15000 AND hours ≥ 100)
- Add input validation for negative numbers
Program 3:
- Add a new mood category: "romantic"
- Calculate and display the most common mood
Create your own programs:
Sequence Programs:
-
YouTube Watch Time Calculator
- Input: videos watched, average length
- Output: total time, equivalent in days
-
Commute Cost Calculator
- Input: distance, fuel price, car efficiency

- Fork this repository
- Start with the flowcharts to understand the logic
- Follow the PRIMM activities in order
- Use Python 3 to run the programs
By completing these activities, you will:
- Understand sequence, selection, and iteration
- Practice reading and tracing code
Some of you will be able to start:
- Learn to modify existing programs
- Build confidence in writing new programs
- Connect visual flowcharts to Python syntax
