Think of the loop-plus-else construct as behaving like this:
while 1:
# Get next element (in a for loop)
if loop_condition: # eg. whether we have an element
# Loop body statement
else:
# Loop else statement
break
Taking the example...
for i in range(10):
print i
else:
print 'the end!'
This is equivalent to...
while 1:
# Get next element (from the range iterator)
if next element: # yes, it's more complicated than this
print i
else:
print 'the end!'
break
Now consider what happens if you put a break statement inside the for
loop.
