-Exercises are grouped into  **concept** exercises which teach the [Python syllabus](https://exercism.org/tracks/python/concepts), and  **practice** exercises, which are unlocked by progressing in the syllabus tree.  Practice exercises are open-ended, and can be used to practice  concepts learned, try out new techniques, and _play_.  These two exercise groupings can be found in the track [`config.json`](https://github.com/exercism/javascript/blob/main/config.json), and under the `python/exercises` directory.

 It's not uncommon that people discover typos, confusing directions, or incorrect implementations of  certain tests or code examples.  Or you might have a great suggestion for a hint to aid students (💙 &nbsp;) ,  see optimizations for exemplar or test code, find some missing test cases to add, or want to correct factual and/or logical errors.  Or maybe you have a great idea for an exercise or feature.
