At least two options (assuming you're on Linux... you
didn't specify your OS unfortunately):

1. Make the scripts executable (+x with chmod), make sure
the folder they are in *is* in the OS path, and put in the
following as the first line of the scripts:

     #!/usr/bin/env python

2. Make your own shell script which knows where to look for your
Python files and execute that instead of "python".  Call it "mypy"
or something to make sure you don't mess up anything else in the
system which wants the normal behaviour with "python".

Note that with your example above, you don't have to use the full
absolute path, as just "python python/export.py temp.dat" would
work.
