11 Data wrangling

It’s great when you can apply Python to a specific domain area.
Whether it’s web development, database management, or mobile apps, Python helps
you get the job done by not getting in the way of you coding your solution. And then
there’s the other types of problems: the ones you can’t categorize or attach to a domain.
Problems that are in themselves so unique you have to look at them in a different, highly
specific way. Creating bespoke software solutions to these type of problems is an area
where Python excels. In this, your final chapter, you’ll stretch your Python skills to the
limit and solve problems along the way.
