This is standard behavior in every language I've ever encountered. If
you are evaluating an and/or with side effects and you need both side
effects to occur, you can trivially write functions implementing this
behavior, e.g.
def a():
print 'foo'
def b():
print 'bar'
def my_and(lh, rh):
return a and b
Then my_and(a(), b()) will evaluate both a and b and print both foo
and bar even though a() is False.
