I have just come across a site that discusses Python's 'for' and
'while' loops as having an (optional) 'else' structure.
At first glance I interpreted it as being a bit like the 'default'
structure in PHP's switch block... But the switch block isn't a loop,
so, I am now confused as to the reason for using 'else' with the for
and while loops...
A few quick tests basically show that statements in the else structure
are executed at the fulfillment of the loop's expression (ie, no
break).
Example:
for i in range(10):
print i
else:
print 'the end!'
