[Tutor] for: how to skip items

[Gabriele Brambilla]

Hi,

I'm wondering how I can (if I can) make a for loop in which I don't use all
the elements.

for example

a100 = list(range(100))

for a in a100:
             print(a)

it print out to me all the numbers from 0 to 99
But if I want to display only the numbers 0, 9, 19, 29, 39, ...(one every
10 elements) how can I do it WITHOUT defining a new list (my real case is
not so simple) and WITHOUT building a list of indexes?

thank you

Gabriele
