Project Description

Pyinter is a small and simple library written in Python for performing interval and discontinous range arithmetic.

>>> pyinter.openclosed(1.1, 12)
(1.1, 12]
>>> discontinous_range = pyinter.IntervalSet([pyinter.closedopen(5, 10), pyinter.closed(22, 23)])
>>> discontinous_range
IntervalSet([5, 10), [22, 23])
>>> 7 in discontinous_range
True
>>> 10 in discontinous_range
False  # This isn't in the range as it is an open interval which doesn't include its end points

Features

  • interval objects which can be
    • unioned
    • intersected
    • easily constructed using helper functions: open, closed, openclosed and closedopen
  • interval sets which can be
    • unioned
    • intersected

Installation

To install Pyinter, simply:

$ pip install pyinter

Or, if you absolutely must:

$ easy_install pyinter

But I’m told you really shouldn’t do that.

Documentation

Documentation is available at http://pyinter.readthedocs.org.

Release History

0.1.9 (2015-08-01)

  • Fix empty interval types so that empty intervals could be compared with other intervals
  • Add method copy() to create new Interval instances with the same bounds and values as the Interval being copied
  • Fix method overlaps on Interval and add tests for it!

0.1.8 (2015-07-14)

  • Fix formatting in README.rst as pypi isn’t rendering it properly.

0.1.7 (2015-07-14)

  • Fix | and & in the documentation.
  • Implement subtraction of Interval’s and IntervalSet’s
  • Add method empty() to detect empty Interval objects.
  • Fix, each infinity should always equal itself.

0.1.6 (2014-05-11)

  • Add a complement function
  • Fix bug with using & and | for union() and intersection()
  • Increase test coverage!

0.1.5 (2013-12-13)

  • Fix the __all__ list so that you can from pyinter import *.
  • Change classes to new style classes (inheriting from object)
  • Added an add() function to the IntervalSet class. This will add (union) an Interval inplace. (similarly to set().add())
  • The optional iterable of Interval objects passed when initialising an IntervalSet is now added Interval by Interval so that initialising with overlapping intervals works as expected.

0.1.4 (2013-11-16)

  • Fix formatting in HISTORY.rst which was stopping the pypi page rendering it.

0.1.3 (2013-11-16)

  • Removed *.md from the MANIFEST file as it warns when installing that no files matching *.md are found.
  • Fix allowing an IntervalSet to be initialised with a generator.

0.1.2 (2013-10-12)

  • Fixed the rendering of the README on pypi (hopefully!) by converting it from a .md file to a .rst file.

0.1.1 (2013-10-09)

  • Adding Manifest file to fix the pypi release. This was broken because the README.md was not being included in the source distribution but setup.py had a reference to this file and therefore failed to run.

0.1.0 (2013-07-03)

  • Initial release
