as to this bit:  having your class inherit from object means it's a
"new-style class".  That's only significant if you're writing code that
is expected to run under Python 2; in Python 3 all classes are new-style
and you don't need to inherit from object to get that - and if you run a
code checker on your program in a Python 3 context, it will likely tell
you so.
