You need to export the variable into the environment, or it's only a
shell variable that isn't inherited by python or other programs.

  $ PYTHONPATH="home/possum/test/kwp"
> $ export PYTHONPATH
  $ printenv PYTHONPATH
  home/possum/test/kwp
  $ python

Just to make it more confusing, if PYTHONPATH were already an environment
variable you wouldn't have had to export it, and there are several ways
to express that export, too:  export NAME=val,  NAME=val export NAME, etc.
