Use the else to let you know that something is going wrong, using raise or exit() or some die() function:
if something:
do_this()
elif something_else:
do_that()
else:
# hope we don't end up here
raise UserWarning('We shouldn't have ended up here')
- beagle3 13y agoBut the discussion is about truthy values and inexact comparisons - avoiding inexact comparisons and having an else means: if something==True: do_this() elif something==False: do_that() else: raise UserWarning("Shouldn't be here") Which is a code smell to me. What I would do is: assert isinstance(something, boolean), "Shouldn't happen" do_this() if something else do_that() (replace assert with something else if you want it not to be optimized away with -O; assert is a debug-only construct in Python. Or just drop the assert altogether. In most places, I would - there's no end to the amount of validation you could do, and most of it is unnecessary)
