ifp_labs

University Python labs from December 2022: three small command-line exercises and a throwaway Django site.

This repository has no practical value. The Django part is a test site built to poke at the framework by hand and see how models, views and templates fit together — nothing more. It stays public as a keepsake from the time when code was still written by hand, one line after another.

What is inside

Path	What it is
lab_1.py	Prints Pascal's triangle with the given number of rows
lab_2.py	Checks whether a sequence of (), [], {} brackets is balanced
lab_3/	Caesar cipher for Russian and English text, file to file
django_crud/	Django site with create / read / update / delete pages for universities and their students

The Django project started from the public rayed/django_crud example and was reworked around a university_fbv app with two models, University and Student, built on function-based views. One of the example's book apps, books_fbv_user, is still in the tree but no longer routed. django_crud/README.md is the original example's README and still describes its book apps.

Running

The command-line labs need only Python 3:

python lab_1.py 5
python lab_2.py "{[()]}"
python lab_3/main.py -l EN -O 3 -i lab_3/input.txt -o lab_3/output.txt

The Django site:

cd django_crud
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cd apps
python manage.py migrate
python manage.py runserver

Then open http://localhost:8000/.
