An interval package for Python.
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
- interval objects which can be
- easily constructed using helper functions: open, closed, openclosed and closedopen
- interval sets which can be
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 is available at http://pyinter.readthedocs.org.
Contributions or suggestions for improvements are welcome.
- Fix: The interval of 2 identical numbers equals the empty set if one of the boundaries is open #20
- Improvement: Add lower and upper properties and replace method which works similarly to date.replace #19
- 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!
- Fix formatting in README.rst as pypi isn’t rendering it properly.
- 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.
- Add a complement function
- Fix bug with using & and | for union() and intersection()
- Increase test coverage!
- 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.
- Fix formatting in HISTORY.rst which was stopping the pypi page rendering it.
- 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.
- Fixed the rendering of the README on pypi (hopefully!) by converting it from a .md file to a .rst file.
- 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.
- Initial release
