Indeed.  The error message was clear on this - but not in a way that's
always instructive until you're used to it :)

"TypeError: print() takes 0 positional arguments but 1 was given"

A method is called "silently" (you didn't pass it yourself as an
argument when you called print()) with the instance, so you need to
declare such a parameter in the method definition.

And to give myself an excuse for preaching: it's usually not a great
idea to reuse the name of a built-in function.
