 0, 9, 19, 29, 39, is not every 10th index

If you want to output every 10th. index try:

a100 = list(range(0,100,10))

for a in a100:
             print(a)

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
