Python is a not a lazy language.
`and` and `or` are particular, they are language constructs (*), not operators,
that's why they can decide whether or not to evaluate their second term. It's a
feature, but this feature is not general to Python.

(*) by this I mean they have similar status as, for example, `if` and `else`
