One-sided card effect

So we’ve established that calling pycmd('ans') from the front template doesn’t work (despite Snoyes’ post I suppose). OK. But the obvious question you’ve been leaving unanswered is, how exactly do you use pycmd('ans') in order to advance cards automatically to the back side. Please keep in mind, I’m just an Anki user—I know note types, I know card types, I know search strings, etc. But I have little familiarity with JavaScript, and even less so with Python. And I know essentially nothing about Anki’s internals. It’s not at all obvious to me how to do this, so if you could state specifically what I’m supposed to do with pycmd('ans'), that would be helpful. Thanks.
