this can be os-sensitive, better to be explicit and use os.path.expanduser()

there are also people arguing https://docs.python.org/3/library/pathlib.html is better than os.path

https://docs.python.org/3/library/pathlib.html

This is in the standard python lib so we are not adding another package. Just import pathlib without pip installing or changing requirements.

@NMontanaBrown ./ will be relative to the current folder.

~ is equivalent to $HOME
