This 'python2-variant' system is used when the Python 2 version of a
package requires some changes beyond simply building everything with
Python 2 instead of Python 3. For example, the Python 2 variant might
require an extra dependency.

In this case, it looks like the Python 2 variant of the package is the
same as the Python 3 variant, aside from the Python version. So, you
should be able to drop the (properties `((python2-variant ...) line from
the python-ptpython package.
I hope that helps!
