#rangedict Build Status Coverage Status

rangedict is a dict whose key can be a range.

##Usage

    >>> from rangedict import RangeDict
    >>> rd = RangeDict()
    >>> rd[(1, 2)] = 1
    >>> rd[(3, 3)] = 3
    >>> rd[(5, 7)] = 5
    >>> print rd[6]
    5
    >>> 3 in rd
    True
    >>> del rd[(3, 3)]
    >>> 3 in rd
    False

Implemented based on red black tree provides an O(logn) complexity for inserting, deleting and finding.

rangedict's Issues

New release

Hi,

I've been the master branch of rangedict successfully with Python 3. But the release on PyPI doesn't contain the newest changes and so doesn't work with Python 3.

Would you please upload the latest code to PyPI as a new release?

Thanks!

how about add support of half-open interval and all-open interval...

English isn’t my first language, so please excuse any mistakes.
like python package https://github.com/kvesteri/intervals, it provides all interval form.
i think about one alter solution that adding a Infinitesimal class.
example:
'(0, 1]' -> d[(0-Infinitesimal, 1)]
'(0, 1)' -> d[(0-Infinitesimal, 1-Infinitesimal)]
'[0, 1)' -> d[(0, 1-Infinitesimal)]

__delitem__ bug?

from rangedict import RangeDict
rd=RangeDict()
rd[(1,2)]=0
rd[(3,4)]=1
rd[(6,7)]=2
del rd[(1,2)]
del rd[(3,4)]

The second del above causes a problem, it seems.
