nit: Can you add the shebang line?

You have to run the program with monkeyrunner and not python.

Move group below standard imports.

Google Python style guide:
Imports are always put at the top of the file, just after any module comments
and doc strings and before module globals and constants. Imports should be
grouped with the order being most generic to least generic:

standard library imports
third-party imports
application-specific imports
