Works fine in Py3, which is what I use now.

I chose not to consider that case, since they were the same length in the
original post. Based on the variable names, it seemed reasonable that
there would always be a 1-to-1

So you could write:

1, 1, 2, 2, 3, 3]))
print list(gen)

Which is exactly the purpose of zip, or its specialization enumerate!
Thanks guys! Looks like the simplest is always the best yet again! :)

Is it possible to write a list comprehension for this so as to produce a

base_scores = range(8, 19)
score_costs = [0, 1, 1, 1, 1, 1, 1, 2, 2, 3, 3]

I can't think of how the structure of the list comprehension would work
in this
