When to use assert

horter than an explicit test followed by a raise. Assert is not a shortcut for lazy coders. * Don't use them for checking input arguments to public library functions (private ones are okay) since you don't control the caller and can't guarantee that it will never break the function's contract. * Don't use assert for any error which you expect to recover from.
