I'm looking for questions to put on a test for students who never had

even write ls.append(...). They write list.append(ls, ...)).
Nitpickery... there *is* OOP in the course, they just don't know it.
Long long ago (over 20 yrs now) I developed a Python course for a
commercial training provider, and in it I claimed one of the great
things about Python was it supported all kinds of object oriented
programming techniques, but you could also use it without doing anything
object oriented. If I wrote a course now, I'd never make that claim,
because everything you do in Python is pretty much object oriented.
>>> x = list()
>>> type(x)
<class 'list'>
>>> dir(x)
['__add__', '__class__', '__class_getitem__', '__contains__',
'__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__',
'__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__',
'__hash__', '__iadd__', '__imul__', '__init__', '__init_subclass__',
'__iter__', '__le__', '__len__', '
__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__',
'__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__',
'__sizeof__', '__str__', '__subclasshook__', 'append', 'clear', 'copy',
'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']
list is a class and it has methods... it's "object-oriented"!
Even if you do
x = 2 + 3
you're actually creating an integer object with a value of 2, and
calling its add method to add the integer object with the value of 3 to
it. The syntax hides it, but in a way it's just convenience that it does
so...
>>> 2 + 3
5
>>> x = 2
>>> x.__add__(3)
5
sorry for nitpicking :) But... don't be afraid of letting them know
it's OOP, and it''s not huge and complex and scary!
