Welcome to Session 4

Learning goals

By the end of Session 4, you should be able to:

• explain serial execution vs process-based parallel execution
• use multiprocessing.Process with start() and join()
• use multiprocessing.Pool for cleaner parallel workflows
• compare serial vs parallel performance on practical tasks

Recommended order

1. Part 1
2. Part 2
3. Homework
4. Write your own work in solutions.
5. Review reference solutions only after attempting tasks yourself.
6. Practice with quizzes when ready.

Notes

• Tutorial and warm-up material is included directly inside each part markdown file.
• Keep your own solutions in separate files inside solutions/.
• Use exercise-style names in solutions/ (for example exercise-04-01.py, exercise-04-02.py).
• For homework, create solutions/exercise-04-homework.md.
• Create your files inside solutions/ as you work through each part.
• Reference answers are in session_solutions/.
• Use if __name__ == "__main__": in multiprocessing scripts.
• If requirements.txt is missing, create it and add:
  • requests==2.32.3
  • Pillow
  • quizmd
• Keep all dependencies in requirements.txt, then install with:
  • pip install -r requirements.txt
