Python - Import package modules before as well as after setup.py install

Assume a Python package (e.g., MyPackage) that consists of several modules (e.g., MyModule1.py and MyModule2.py) and a set of unittests (e.g., in MyPackage_test.py).

.
├── MyPackage
│   ├── __init__.py
│   ├── MyModule1.py
│   └── MyModule2.py
├── README.md
├── requirements.txt
├── setup.py
└── tests
    └── MyPackage_test.py

I would like to import functions of MyModule1.py within the unittests of MyPackage_test.py. Specifically, I would like to import the functions both before as well as after package installation via setup.py install MyPackage.

Currently, I am using two separate commands, depending on the state before or after package installation:

# BEFORE
import sys, os
sys.path.append(os.path.join(os.path.dirname(__file__), '..', 'MyPackage'))

# AFTER
import MyPackage

Can this be done with a single command?

in pycharm IDE you can can import method easily.by setting the working directory to the folder which contains all files.
And, then in MyPackage __init__.py file import all the function from MyModule1.py and MyModule2.py .
then in MyPackage_test.py you can use

import MyPackage 
from MyPackage import xyz

Option 1:

It seems that the following command does what I need:

sys.path.append(os.path.join(__file__.split(__info__)[0] + __info__), __info__)

Option 2:

Depending on the location of __init__.py, this also works:

sys.path.append(os.path.dirname(os.path.split(inspect.getfile(MyPackage))[0]))

Option 3:

Moreover, the ResourceManager API seems to offer additional methods.
