Need to understand how to import module in python from one directory up

Question

I have a structure like this

pkg1
   __init__.py  
   file_1.py
   file2.py
pkg2
   test_1.py
   __init__.py

I have a structure like above. I have a code in test_1.py which is trying to load file_1.py

#test_1.py

from pkg1 import file_1
# from .. import file_1

Both statements are not working. How can I import the file_1 from pfg1

Make pkg2 a package with `__init__.py` and if it's `pytest` invoke it as `python -m pytest` — Nizam Mohamed, Dec 25 '20 at 13:46
I tried this but not working. I already have a __init__.py which I forgot to mention above — Sumit, Dec 25 '20 at 13:47

I am not using unittest or pytest. why should I use pytest or unittest. It is not mandatory — Sumit, Dec 25 '20 at 13:56
Any idea using import statement without using env variables. How can i use absolute imports here — Sumit, Dec 25 '20 at 14:02

To use absolute import, pkg1 has to be in Python's import path. — Nizam Mohamed, Dec 25 '20 at 14:33
pkg1 and pkg2 are unrelated. You can only use absolute import here. — Nizam Mohamed, Dec 25 '20 at 14:43

A python program can modify its path by adding elements to sys.path directly. import sys then you can add to the system-path at runtime:

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

or you can do this:

    import sys
    import os
    
    base_dir = os.path.dirname(__file__) or '.'

    # Insert the package_dir_a directory at the front of the path.
    package_dir_a = os.path.join(base_dir, 'package_dir_a')
    sys.path.insert(0, package_dir_a)
    import py_file
