SequencePointTiers have all the same methods and attributes as TierMixins and WithinMixins

Parameters

Name	Type	Description	Default
tier	list[Point] | list[SequencePoint] | PointTier | Self	A list of SequencePoints, or another SequencePointTier	[]
entry_class	Type[SequencePoint]	A SequencePoint subclass	None

Examples

from aligned_textgrid import SequencePoint, SequencePointTier

point_a = SequencePoint((0,"a"))
point_b = SequencePoint((1, "b"))

point_tier = SequencePointTier([point_a, point_b])

print(point_tier)

Sequence Point tier of SequencePoint;

print(point_tier.sequence_list)

[Class SequencePoint, label: a; tier_index: 0, Class SequencePoint, label: b; tier_index: 1]
