Python: Need help importing module from a different directory

I'm running Python3.6 on Mac OSX 10.12.4

/Documents/PyProjects/modules/

In that directory, resides __init__.py and Pyrime.py. Pyrime.py has some functions in it.

/Documents/PyProjects/PE010/

In that directory resides my program: PE010_Summation_of_Primes.py. I want to import one function, called is_prime, in Pyrime.py to use in PE010_Summation_of_Primes.py. I thought all I would need to do is write, in PE010_Summation_of_Primes.py:

from modules.Pyrime import is_prime

This doesn't work. My terminal throws:

Traceback (most recent call last):
  File "PE010_Summation_of_Primes.py", line 1, in <module>
    from Pyrime import is_prime
ModuleNotFoundError: No module named 'Pyrime'

Python is the first language I've ever seen, and I've only seen it for about a week so far. I've looked at a lot of documentation, but for a beginner like me, it hasn't been very enlightening.

Well, python refers the global library directory or local directory when trying to import a file. But for files in directories other than local you can either add file path to sys.path or create a __init__.py file in all directories including the parent directory PyProjects. Try this -

from modules.Pyrime import is_prime

So your directory will look something like this -

PyProjects
    -- __init__.py
    -- PE010
        -- __init__.py
        -- PE010_Summation_of_Primes.py
    -- modules
        -- __init__.py
        -- Pyrime.py

Hope it helps.

Add the system-path at runtime:

import sys
sys.path.insert(0, 'path/to/your/py_file')
import py_file

it will work!
