Notes

There is no guaranteed ordering to the definite sequences that are yielded.

Each definite sequence will have the same type, metadata, and positional metadata as the biological sequence.

Examples

>>> from skbio import DNA
>>> seq = DNA('TRG')
>>> seq_generator = seq.expand_degenerates()
>>> for s in sorted(seq_generator, key=str):
...     s
...     print('')
