__getitem__
(indexable)[source]¶Slice this sequence.
State: Stable as of 0.4.0.
Notes
This drops the self.interval_metadata
from the returned
new Sequence
object.
indexable (int, slice, iterable (int and slice), 1D array_like (bool)) – The position(s) to return from this sequence. If indexable is an
iterable of integers, these are assumed to be indices in the
sequence to keep. If indexable is a 1D array_like
of
booleans, these are assumed to be the positions in the sequence to
keep.
New sequence containing the position(s) specified by indexable in this sequence. Positional metadata will be sliced in the same manner and included in the returned sequence. metadata is included in the returned sequence.

>>> from skbio import Sequence
>>> s = Sequence('GGUCGUGAAGGA')
