Everyday I add a new Python One Liner to my Medium blog. Sometimes they are deceptively simple but merit a deep dive and others just demonstrate basic language features. The motivation for this project is to keep myself learning new things about the Python language everyday and to encourage a wider dialog and collaboration with others in the Python community. Feel free to leave comments on the blog or better yet clone the repo and contribute to the project.
This project is just for fun and doesn't seek to enforce any hard and fast rules, but it does make sense to provide a basic description of what is meant by the term "One Liner"
Note: These guidelines are completely subject to change!
- All of the One Liners are going to be written with Python 3.6 and up.
- One Liner should not greatly exceed the line length as described in the PEP8, which is currently 72 characters. Update: I have not adhered to this at all!
importstatements don't count as lines.- One or two variables declared before a One Liner don't count as lines.
- A One Liner should not use third party libraries. There is plenty to explore in the standard library!
