Somewhat feebly, if you don't mind my saying so, but don't worry.
The usual way to proceed in the face of such ignorance is to insert some
form of output that will tell you the answer to your question.
So:

Remember how Python's range operator works. range(n, x) constructs a list
that consists of all elements starting with n and up to, but /not
including/, x.
|So what is n and x in the first iteration? Sorry. I'm trying.
When n == 2, the inner loop executes 0 times (the length of range(2,n)) and
then falls thru to the else clause, printing the correct answer.

Hi,
I noticed that the 'for' loop can be used inline with a list definition. For
example:
print [i for i in mylist]
My first question is what is the name for this? I couldn't find this usage
in the python docs; I only managed to learn about it through code samples on
the internet.
Secondly, I'm
