Regular Expressions for Data Scientists in Python

An oldie but goodie. Regular Expressions are a must for anybody using Python, doing Data Science, or just ETL’ing data.

Regular expressions (regex) are essentially text patterns that you can use to automate searching through and replacing elements within strings of text. This can make cleaning and working with text-based data sets much easier, saving you the trouble of having to search through mountains of text by hand.
