New in version 1.1.
Yield outer product of sequences:
abjad> from abjad.tools import sequencetools
abjad> list(sequencetools.yield_outer_product_of_sequences([[1, 2, 3], ['a', 'b']]))
[[1, 'a'], [1, 'b'], [2, 'a'], [2, 'b'], [3, 'a'], [3, 'b']]
abjad> list(sequencetools.yield_outer_product_of_sequences([[1, 2, 3], ['a', 'b'], ['X', 'Y']]))
[[1, 'a', 'X'], [1, 'a', 'Y'], [1, 'b', 'X'], [1, 'b', 'Y'],
[2, 'a', 'X'], [2, 'a', 'Y'], [2, 'b', 'X'], [2, 'b', 'Y'],
[3, 'a', 'X'], [3, 'a', 'Y'], [3, 'b', 'X'], [3, 'b', 'Y']]
abjad> list(sequencetools.yield_outer_product_of_sequences([[1, 2, 3], [4, 5], [6, 7, 8]]))
[[1, 4, 6], [1, 4, 7], [1, 4, 8], [1, 5, 6], [1, 5, 7], [1, 5, 8],
[2, 4, 6], [2, 4, 7], [2, 4, 8], [2, 5, 6], [2, 5, 7], [2, 5, 8],
[3, 4, 6], [3, 4, 7], [3, 4, 8], [3, 5, 6], [3, 5, 7], [3, 5, 8]]
Return generator.
Changed in version 2.0: renamed sequencetools.outer_product() to sequencetools.yield_outer_product_of_sequences().
