Which is better done by 'num += 10'.
Can you come up with an example that isn't trivially replaced with
clearer code? That might make it clearer what your concern is.

In such cases, the name 'dummy' is conventionally bound to the items
from the iterator, for clarity of purpose::
for dummy in range(10):
# do stuff that makes no reference to 'dummy'
Also note that 'range' will return an iterator (not a list) in Python
3.0, and 'xrange' is removed since it's then obsolete
