New in version 1.1.
Replace sequence elements cyclically at indices with new_material:
abjad> from abjad.tools import sequencetools
abjad> sequencetools.replace_sequence_elements_cyclically_with_new_material(range(20), ([0], 2), (['A', 'B'], 3))
['A', 1, 'B', 3, 4, 5, 'A', 7, 'B', 9, 10, 11, 'A', 13, 'B', 15, 16, 17, 'A', 19]
abjad> sequencetools.replace_sequence_elements_cyclically_with_new_material(range(20), ([0], 2), (['*'], 1))
['*', 1, '*', 3, '*', 5, '*', 7, '*', 9, '*', 11, '*', 13, '*', 15, '*', 17, '*', 19]
abjad> sequencetools.replace_sequence_elements_cyclically_with_new_material(range(20), ([0], 2), (['A', 'B', 'C', 'D'], None))
['A', 1, 'B', 3, 'C', 5, 'D', 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
abjad> sequencetools.replace_sequence_elements_cyclically_with_new_material(range(20), ([0, 1, 8, 13], None), (['A', 'B', 'C', 'D'], None))
['A', 'B', 2, 3, 4, 5, 6, 7, 'C', 9, 10, 11, 12, 'D', 14, 15, 16, 17, 18, 19]
Raise type error when sequence not a list.
Return newly constructed list.
Changed in version 2.0: renamed sequencetools.replace_elements_cyclic() to sequencetools.replace_sequence_elements_cyclically_with_new_material().
