For that matter even this works
But I am not sure whats happening or that I like it
[x[-2:] for x in lines]
['12', '42', '49', '56', '25', '36', '49', '64', '81', '00']
x[-2:] selects all items in the sequence with index i such that len(x)
- 2 <= i < len(x). For a sequence of length 2 or less, that's the
entire sequence.
Thanks -- learn something
So it means that indices can give indexerror; slices cannot?
Seems fair enough put that way, but is visually counterintuitive
Are you seriously trying to say that you teach Python but don't
understand a basic that is here
https://docs.python.org/3/tutorial/introduction.html, "Slice indices
have useful defaults; an omitted first index defaults to zero, an
omitted second index defaults to the size of the string being sliced."?
