It's actually quite simple, just add a bbappend to the python recipe that puts 
all .py files into the "dbg" or newly created "src" package. Or simply delete 
all .py files in a do_install_append.


Here's an example of the "src" approach:

https://github.com/OpenPLi/openpli-oe-core/blob/develop/meta-openpli/recipes-devtools/python/python_2.7.13.bbappend


Simply doing this in the bbappend might also work (untested):

do_install_append() {
	find ${D}${libdir}/python${PYTHON_MAJMIN}/ -name '*.py' -remove
}


Removing the ".py" files roughly cuts the disk space in half.


The "src" approach works on any package, and has the advantage that you can 
still install the source files for debugging and development.
