It's letting you know that the item isn't in the list. There's no
sensible return value from an "index" function in that condition.

You can easily create one:
def get_an_index_even_if_not_found(the_list, the_item):
bogus_index_value = object()
try:
index = the_list.index(the_value)
except ValueError:
index = bogus_index_value
return index
It's up to you to figure out what bogus_index_value you want to
use. The rest of us will continue to catch the exception where needed.
