🐍 python_scripts_rcsmit

A workshop floor of standalone Python scripts — experiments, utilities, scrapers, games, visualisations and one-off tools by René Smit.

GitHub → github.com/rcsmit/python_scripts_rcsmit
Interactive apps → rcsmit.streamlit.app

Unlike the Streamlit portfolio, this repo is the workshop floor — scripts that run locally, produce output files, prototype ideas, or do things that don't need a browser. Some became Streamlit apps later. Some are just here for reference.

Running a script

Most scripts are self-contained. Clone the repo and run:

git clone https://github.com/rcsmit/python_scripts_rcsmit
cd python_scripts_rcsmit
pip install -r requirements.txt   # if present, or install deps per script
python script_name.py

Scripts that need API keys expect either a .env file (copy .env.example) or a populated keys_dummy.py.
