Re: ModuleNotFoundError in Terminal, PyCharm OK

Hi dn,

#1 was not very useful, but #5
https://docs.python.org/3/reference/import.html#:~:text=5.4.5.-,module.__path__,search%20for%20modules%20during%20import.
was
quite useful

I discovered that bash had no PYTHONPATH environment variable, and that
PyCharm had obligingly intelligently populated it.  (And if I changed the
file structure, I had to manually inform PyCharm I had changed it, even if
I used the "refactor" feature.)

I wound up with this:

# shdroll.py
import sys
sys.path.extend(['../../..',               # Important
                 '../../../src',           # Stuff
                 '../../../src/core'])     # Here
from simple_hdroll_cli_parser import SimpleHDRollCliParser
from src.core import core

parse_cli_args = SimpleHDRollCliParser()
kwargs = parse_cli_args.parse()

if kwargs.add is not None:
    transform = core.add_currying(kwargs.add)
elif kwargs.mult is not None:
    transform = core.multiply_currying(kwargs.mult)
else:
    transform = None  # not strictly necessary, but it makes my brain hurt
less

# Create a die
die = core.IntegerDie(transform_fn=transform,
                      sides=kwargs.sides,
                      bottom=kwargs.base)

print(rolls.to_string())

-------

I also wound up with a src.py file in the ./hackable_dice_roller/src
directory so it would stop complaining about a missing module in the src
package.  src.py has one line.

from src.core import core

Was that what you had in mind, or did I come up with a singularly ugly and
unPythonic solution?
