setting pythonpath variable in environment variables

[Gribouillis]

Python imports modules. It means that when you write from one.sample1 import *, there is an importable module or package named one. Here are a few ways to achieve this:

• Move the 'one' directory in 'two'. It will become importable in 'sample.py'
  
• Put the directory containing 'one' on the python path by manipulating the python path through the PYTHONPATH environment variable or the files usercustomize.py or sitecustomize.py
  
• Manipulate sys.path in 'sample.py' to make sure it contains the directory containing 'one'.
  

As you added an '__init__.py' file in 'parent', it may happen that you want 'one' or 'two' to be subpackages of module 'parent'. In that case you can put 'parent' on the python path instead of 'one' and just write from ..one.sample1 import * in 'sample.py' and invoke the script with the command python -m parent.two.sample.
