Automate Data Cleaning with User-Defined Functions, Classes, and Pipelines
There are a number of great reasons to write code that is reusable. When we step back from the particular data-cleaning problem at hand and consider its relationship to very similar problems, we can actually improve our understanding of the key issues involved. We are also more likely to address a task systematically when we set our sights more on solving it for the long term than on the before-lunch solution. This has the additional benefit of helping us to disentangle the substantive issues from the mechanics of data manipulation.
We will create several modules to accomplish routine data-cleaning tasks in this chapter. The functions and classes in these modules are ...
