That is technically correct, you could do that. That's a good example of
the syntax of the `if` expression, but it's a bad example of where to
use it:
(1) it only works in Python 2.5 or better; and
(2) experienced Python programmers will laugh at you :)
with all due respect to Alan who suggested it. It really is an
unnecessarily complicated and verbose way of doing a simple assignment,
nearly as bad as writing this:
if len(mystring) == 0:
n = 0
else:
n = len(mystring)
instead of just
n = len(mystring)
