babel.plural.to_gettext

All Samples(6) | Call(6) | Derive(0) | Import(0)

The plural rule as gettext expression.  The gettext expression is
technically limited to integers and returns indices rather than tags.

>>> to_gettext({'one': 'n is 1', 'two': 'n is 2'})
'nplurals=3; plural=((n == 1) ? 0 : (n == 2) ? 1 : 2)'

:param rule: the rules as list or dict, or a `PluralRule` object
:raise RuleError: if the expression is malformed
