Python Brain Teasers

Make your good Python code even better by following proven and effective

pythonic programming tips. Avoid logical errors that usually go

undetected by Python linters and code formatters, such as frequent data

look-ups in long lists, improper use of local and global variables, and

mishandled user input. Discover rare language features, like rational

numbers, set comprehensions, counters, and pickling, that may boost your

productivity. Discover how to apply general programming patterns,

including caching, in your Python code. Become a better-than-average

Python programmer, and develop self-documented, maintainable,

easy-to-understand programs that are fast to run and hard to break.
