Imagine that you've been working on this program on a team of developers. You've done all the right things up until now, including writing unittests.
Unfortunately, a previous teammate not only committed code that made the benchmarking tests fail, but they force-pushed to master after rewriting history, so you can't simply go back in the git history to fix things. Especially since, in the process of ruining the timings, the developer did manage to implement features that weren't there before.
Your task is to modify anagrams.py such that the tests pass again. If the problem isn't obvious to you by visually examining the anagrams.py
module, consider using the profiling techniques that you learned about in the lesson to pin down the problem. Using a debugger may also help you to get a handle on exactly why things are slow.
If you look at the test case, you'll notice that the test_long
unit test is currently being skipped. That's because if it were to run with the current implementation of find_anagrams
it would take several minutes to complete. We suggest that you try and get the test_short
to pass first, then remove the @unittest.skip
line and ensure that the tests still pass.
You can run the tests from the command line with the unittest framework. From the top level directory of the assignment, use the following command:
$ python -m unittest discover
VSCode also has a built-in test discovery feature, but it requires you to enable test discovery in the settings. Read this article for more information about how to configure VSCode for automatic test discovery.

Be sure to select the configuration for unittest
, not nosetest or pytest because these are third-party libraries that you would have to install. The file discovery pattern to configure is test_*.py
- Fork this repository into your own personal github account.
- Then Clone your own repo to your local development machine.
- Create a separate branch named
dev
, and checkout the branch. - Commit your changes, then
git push
the branch back to your own github account. - From your own Github repo, create a pull request (PR) from your
dev
branch back to your own master. - Copy/Paste the URL link to your PR as your assignment submission.
- Your grader will post code review comments inline with your code, in your github account. Be sure to respond to any comments and make requested changes. RESUBMIT a new link to your PR after making changes. This is the code review iteration cycle.
