Python On Windows

Set up python on Windows

• add python to PATH

 The python part of the 'python setup.py install' idiom needs to be omitted on
 Windows, but that does not mean that the solution is to automatically add it
 to PATH.

• PYTHONPATH - where to find scripts - so that import works
  • navigate in registry to HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore - select python-version, then change pythonpath
    • add a new key to the key pythonpath - name the key according to the project that addition belongs to - that way one can track the changes\additions more conveniently. [1]
  • or - alternatively - set\change the environment-variable pythonpath - like changing path. [2]
  • the registry-entry and the environment-variable augment each other.
