textworld.utils.unique_product(*iterables)[source]

Cartesian product of input iterables with pruning.

This method prunes any product tuple with duplicate elements in it.

Example

unique_product(‘ABC’, ‘Ax’, ‘xy’) –> Axy BAx BAy Bxy CAx CAy Cxy

Notes

This method is faster than the following equivalent code:

>>> for result in itertools.product(*args):
>>>     if len(set(result)) == len(result):
>>>         yield result
textworld.utils.uniquify(seq)[source]
