a Range class implementing compact integer ranges with a set-like API, and associated functions

Project description

A Range is an object resembling a set but optimised for contiguous ranges of int members.

Function overlap(span1, span2)

Return a list [start,end] denoting the overlap of two spans.


>>> overlap([1,9], [5,13])
[5, 9]

Class Range

A collection of ints that collates adjacent ints.

The interface is as for a set with additional methods:

  • spans(): return an iterable of Spans, with .start included in each Span and .end just beyond

Additionally, the update/remove/etc methods have a secondary calling signature: (start,end), which is the same as passing in Range(start,end) but much more efficient.

Class Span

MRO: Span, builtins.tuple
A namedtuple with .start and .end attributes.

Function spans(items)

Return an iterable of Spans for all contiguous sequences in items.


>>> list(spans([1,2,3,7,8,11,5]))
[1:4, 7:9, 11:12, 5:6]
