I sometimes think that way, but when I do ask I ask why you can use any non-Boolean in a conditional? That's optional too. As for uses: because empty lists, zero and empty strings are false, you can do things like: if validation_errors: if special_instructions: if unusued_widgets: Of course those are just saved keystrokes, and can lead to bugs, but so is being able to throw a list into a condition.
