-We often think of data analysis as just the resulting report, insights, or visualizations. Even though these end products are generated by code, it's easy to focus on making the products _look nice_ and ignore the _quality of the code that generates them_. While these end products are generally the main event, **code quality is still important**! And we're not talking about bikeshedding the aesthetics or pedantic formatting standards — it's ultimately about correctness and reprodcibility.

 It's no secret that good analyses are often the result of very scattershot and serendipitous explorations, tentative experiments, and rapidly testing what works and what doesn't. That is all part of the process for getting to the good stuff, and there is no magic bullet to turn data exploration into a simple, linear progression. That being said, once started it is not a process that lends itself to thinking carefully about the structure of your code or project layout.
