Types related to splitting data.

Module Attributes

DatetimeTypes	Types that may be cast to pandas.Timestamp.
DatetimeIterable	Iterable that may be cast to pandas.DatetimeIndex.
TimedeltaTypes	Types that may be cast to pandas.Timedelta.
Schedule	User schedule type.
Span	User span type.
Flex	Flexibility frequency string for floor/ceil.
DatetimeSplits	A list of bounds.

Classes

DatetimeIndexSplitterKwargs	Keyword arguments for creating a DatetimeIndexSplitter.
DatetimeSplitBounds(start, mid, end)	A 3-tuple which denotes two adjacent datetime ranges.
DatetimeSplitCounts(data, future_data)	Relative importance of data and future_data.

DatetimeTypes: TypeAlias = str | pandas._libs.tslibs.timestamps.Timestamp | datetime.datetime | datetime.date | numpy.datetime64

Types that may be cast to pandas.Timestamp.

DatetimeIterable

Iterable that may be cast to pandas.DatetimeIndex.

alias of Iterable[str | Timestamp | datetime | date | datetime64]

TimedeltaTypes: TypeAlias = str | pandas._libs.tslibs.timedeltas.Timedelta | datetime.timedelta | numpy.timedelta64

Types that may be cast to pandas.Timedelta.

Schedule

User schedule type.

alias of Union[DatetimeIndex, Iterable[str | Timestamp | datetime | date | datetime64], str, Timedelta, timedelta, timedelta64]

Span

User span type. Used to determine limits from the timestamps given by a Schedule.

alias of Union[int, Literal[‘all’], str, Timedelta, timedelta, timedelta64]

Flex

Flexibility frequency string for floor/ceil. Pass False to disable.

alias of Union[bool, Literal[‘auto’], str]

class DatetimeSplitBounds(start: Timestamp, mid: Timestamp, end: Timestamp)

Bases: NamedTuple

A 3-tuple which denotes two adjacent datetime ranges.

start: Timestamp

Left (inclusive) limit of the data range.

mid: Timestamp

Schedule timestamp.

Right (exclusive) limit of the data range, left (inclusive) limit of the future_data range.

end: Timestamp

Right (exclusive) limit of the future_data range.

DatetimeSplits

A list of bounds.

alias of list[DatetimeSplitBounds]

class DatetimeSplitCounts(data: int, future_data: int)

Bases: NamedTuple

Relative importance of data and future_data.

data: int

Alias for field number 0

future_data: int

Alias for field number 1

class DatetimeIndexSplitterKwargs

Bases: TypedDict

Keyword arguments for creating a DatetimeIndexSplitter.

The DatetimeIndexSplitter is the backing type for all splitting logic. It is not exposed directly to users. See split() or one of the related functions for user-facing APIs.

schedule: DatetimeIndex | Iterable[str | Timestamp | datetime | date | datetime64] | str | Timedelta | timedelta | timedelta64

before: int | Literal['all'] | str | Timedelta | timedelta | timedelta64

after: int | Literal['all'] | str | Timedelta | timedelta | timedelta64

step: int

n_splits: int | None

flex: bool | Literal['auto'] | str
