I was not being able to compile tvheadend on focal-amd64 because of the python-requests.
After looking at it i changed the debian/control from ..., python | python3, python-requests | python3-requests,... to ..., python3, python3-requests,... and it compiled.
Somehow the | are not being well understand and always look for python and python-requests.
