Should've re-read your first message before I replied:

- "CLN: camper_program.py: Cleanup camper program codestyle with black and

  https://github.com/4dsolutions/python_camp/pull/3
- "TST: camper_program.py: tests and exception handlin"
  https://github.com/4dsolutions/python_camp/pull/4

more or less helpful than just reviewing the (commits in the) PR
