Learning from bidict -------------------- One of the most rewarding things about bidict is the outsized amount of advanced Python it covers in light of its small codebase. Check out :doc:`learning-from-bidict` [#fn-learning]_ if you're interested in learning more. Contributing ------------ Bidict is currently a one-person operation maintained on a voluntary basis with no other sponsorship. Your help would be most welcome! Reviewers Wanted! ^^^^^^^^^^^^^^^^^ One of the most valuable ways to contribute to bidict and to explore some advanced Python [#fn-learning]_ while you're at it is to review bidict's relatively small codebase. Please create an issue or pull request with any improvements you'd propose or any other results you found. (Submitting a "Nothing-to-merge" PR with feedback in inline code comments or a `Review results `__ issue both work well.) You can also +1 `this issue `__ to sign up to give feedback on future proposed changes that are in need of a reviewer. Giving Back ^^^^^^^^^^^ .. duplicated in CONTRIBUTING.rst (would use `.. include::` but GitHub doesn't understand it) Bidict is the product of hundreds of hours of unpaid, voluntary work. If bidict has helped you accomplish your work, especially work you've been paid for, please consider chipping in toward the costs of bidict's maintenance and development and/or ask your organization to do the same. .. image:: https://raw.githubusercontent.com/jab/bidict/master/assets/support-on-gumroad.png :target: https://gumroad.com/l/bidict :alt: Support bidict Finding Documentation --------------------- If you're viewing this on ``__, note that multiple versions of the documentation are available, and you can choose a different version using the popup menu at the bottom-right.
