 The Makefile also contains other useful commands for developing. To run all of the unit tests present in `src/tests/`, use `make test` within the REPL. To execute the linters, use `make check-lint` (or `make lint` to automatically fix common linter issues and then run the linters). Note that this command also runs a typechecker which takes advantage of Python's type hinting feature, so it can help catch errors. It is _*very highly*_ recommended that the linter is executed before any commits are pushed. If pylint makes a recommendation you disagree with, it is possible to disable that pylint check within the section of code you are working in.
