skbio.sequence.RNA.__eq__

RNA.__eq__(other)[source]

Determine if this sequence is equal to another.

State: Stable as of 0.4.0.

Sequences are equal if they are exactly the same type and their sequence characters, metadata, and positional metadata are the same.

Parameters

other (Sequence) – Sequence to test for equality against.

Returns

Indicates whether this sequence is equal to other.

Return type

bool

Examples

Define two Sequence objects that have the same underlying sequence of characters:

>>> from skbio import Sequence
>>> s = Sequence('ACGT')
>>> t = Sequence('ACGT')

The two sequences are considered equal because they are the same type, their underlying sequence of characters are the same, and their optional metadata attributes (metadata and positional_metadata) were not provided:

>>> s == t
True
>>> t == s
True

Define another sequence object with a different sequence of characters than the previous two sequence objects:

>>> u = Sequence('ACGA')
>>> u == t
False

Define a sequence with the same sequence of characters as u but with different metadata, positional metadata, and interval metadata:

>>> v = Sequence('ACGA', metadata={'id': 'abc'},
...              positional_metadata={'quality':[1, 5, 3, 3]})
>>> _ = v.interval_metadata.add([(0, 1)])

The two sequences are not considered equal because their metadata, positional metadata, and interval metadata do not match:

>>> u == v
False
