How many parameters are there? len(self.param)
Make that many placeholders and then join them together with
commas:

I prefer the clarity of Peter Otten's suggestion of
', '.join('?' * len(self.param))
over the mild obscurity of putting it in a list before
multiplying.
As long as the OP doesn't try to transfer this to other paramstyles:

I chose the list form for just this reason, because the OP said he was
"very new to Python".
