If you want to, these are some additional things you could try: * Remove as much duplication as you possibly can. * Optimize for readability, even if it means introducing duplication. * If you've removed all the duplication, do you have a lot of conditionals? Try replacing the conditionals with polymorphism, if it applies in this language. How readable is it? Then please share your thoughts in a comment on the submission. Did this experiment make the code better? Worse? Did you learn anything from it? ### Submitting Exercises Note that, when trying to submit an exercise, make sure the solution is in the `exercism/python/` directory. For example, if you're submitting `bob.py` for the Bob exercise, the submit command would be something like `exercism submit /python/bob/bob.py`. For more detailed information about running tests, code style and linting, please see the [help page](http://exercism.io/languages/python). ## Source Learn to Program by Chris Pine [http://pine.fm/LearnToProgram/?Chapter=06](http://pine.fm/LearnToProgram/?Chapter=06) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
