The two arguments are not interchangeable as `alternative` may contain less placeholders if `format` uses named placeholders. The behavior of this function is undefined if the string does not use string formattings. If the string formatting of `alternative` is compatible to `format` the function returns `None`, otherwise a `TranslationError` is raised. Examples for compatible format strings: >>> _validate_format('Hello %s!', 'Hallo %s!') >>> _validate_format('Hello %i!', 'Hallo %d!') Example for an incompatible format strings: >>> _validate_format('Hello %(name)s!', 'Hallo %s!') Traceback (most recent call last): ...
