five and two
2
I understand what it's doing here: returning the operand. But what is the
practical application of that? How might I use that function?
Try
bool(2)
True
bool(0)
False
So you can use the retuirn from the and as a boolean value in a test
condition:
if 5 and 2:
print 'its true')
if 5 and 0:
print 'its not'
(I know how binary Booleans work etc., so this is a bit of a change of
outlook.)
Hopefully that clears it up.
There are some klunky hacks that you can do based on this side-effect
but there are usually cleaner solutions especially since Pyton 2.5
introduced a ternary operator
