Generic operations for indexing, generating, and iterating over sequences

Attributes

T
S

Functions

is_unique(→ bool)	Whether or not a Sequence contains repeating items
int_complement(→ Generator[int, None, None])	Generate ordered non-negative integers which don't appear in a sequence of integers
pad_sequence(→ list[Union[T, S]])	Pad a given list with a particular value
cycle_items(→ list[T])	Cyclically shift all items in a sequence over by the target number of indices

polymerist.genutils.sequences.seqops.is_unique(seq: Sequence) → bool

Whether or not a Sequence contains repeating items

polymerist.genutils.sequences.seqops.int_complement(integers: Sequence[int], bounded: bool = False) → Generator[int, None, None]

Generate ordered non-negative integers which don’t appear in a sequence of integers

polymerist.genutils.sequences.seqops.pad_sequence(target_list: Sequence[T], to_length: int, pad_value: S = 0, from_left: bool = False) → list[T | S]

Pad a given list with a particular value

polymerist.genutils.sequences.seqops.cycle_items(seq: Sequence[T], places: int = 1) → list[T]

Cyclically shift all items in a sequence over by the target number of indices By default shifts right, but can also move to left with negative “places” argument

Examples:

cycle_items([1,2,3,4], 2) -> [3,4,1,2] cycle_items([1,2,3,4], -1) -> [4,1,2,3]
