I am currently using Python 3.11.4.
First I want to say: f-strings are great! I use them all the time,
mostly but by no means exclusively for debug messages. And in 3.12 they
will get even better.
And the improved error messages in Python (since 3.9) are great too!

Hi,
The range function in Python 2.7 (and yes, I know that it is now
superseded), provokes a Memory Error when asked to deiliver a very long
list of values.
I assume that this is because the function produces a list which it then
iterates through.
1. Does the range function in Python 3.x

Yeah, that's what assers are for. Or rather for things that you *think*
are true.

Curiously, this does not even occur during an assert exception -
despite the value/relationship being the whole point of using
the command!
x = 1
assert x == 2
AssertionError (and that's it)
Sometimes you can use a second parameter to assert if you know what kind of
error
t x == 2

x = 1
assert x == 2

Sometimes you can use a second parameter to assert if you know what kind
of error to expect:
>>> a = [1,2,3]
>>> b = [4,5]
>>> assert len(a) == len(b)

Not very often, but I do use it.
plaining that Python does not
work the way it 'should'. In turn, gives rise to the impression that
expounding the advantages of TDD, and thus anticipating such unit and
integration error-possibilities, might be considered an insult or unhelpful.
(sigh!)
Personally, I struggled a bit to adapt from
