Structural pattern matching is coming in Python 3.10. This article explores how to use it to write Pythonic code by searching for some of the best use cases for the match statement. Keep in mind that match is still in alpha, so, while unlikely, some things may still change before the final version of 3.10 is released.

The pandas library provides easy-to-use data structures like pandas DataFrames as well as tools for data analysis. One issue with pandas is that it can be slow with large amounts of data. It wasn’t designed for analyzing 100 GB or 1 TB datasets. Fortunately, there is the Modin library which has benefits like the ability to scale your pandas workflows by changing one line of code.
