I might be missing something but I can't see a reason for the "else:"

where or why someone might use the "else:" clause with the for loop?
There have been a couple of sample cases given already but here is an
example of what you would need to do without it.
broken_loop = False
for item in collection:
process(item)
if condition:
broken_loop = True
break
if not broken_loop:
do_the_else_part()
do_this_regardless()
It's not a huge pain but this is easier:
for item in collection:
process(item)
if condition:
break
else:
do_the_else_part()
do_this_regardless()
