As the error suggests, you don't have a "clean" target in your Makefile. dpkg-buildpackage needs this so that your package can delete the helloworld.py if the user decides to remove the package later on.

If you read the first post carefully, you'll notice this line near the top of the example rules file:

include /usr/share/cdbs/1/rules/debhelper.mk
This line includes a lot of debhelper targets, including the missing "clean" one. Hopefully adding this line will resolve the issue you're seeing.
