Put this at the top of your  py file  for python 2 x      usr bin env python    or for python 3 x     usr bin env python3   This should look up the python environment  without it  it will execute the code as if it were not python code  but straight to the CLI  If you need to specify a manual location of python environment put      path  to  python

No  it s not the script  it s the fact that your script is not executed by Python at all  If your script is stored in a file named script py  you have to execute it as python script py  otherwise the default shell will execute it and it will bail out at the from keyword   Incidentally  from is the name of a command line utility which prints names of those who have sent mail to the given username  so that s why it tries to access the mailboxes    Another possibility is to add the following line to the top of the script      usr bin env python   This will instruct your shell to execute the script via python instead of trying to interpret it on its own
