In the previous chapter, we performed a series of data wrangling and cleaning processes on our metadata in order to convert it into a form that was more usable. To avoid having to perform these steps again, let's save this cleaned DataFrame into a CSV file. As always, doing this with pandas happens to be extremely easy.

df.to_csv('../data/metadata_clean.csv', index=False)

Your data folder should now contain a new file, metadata_clean.csv.

Let's create a new folder, Chapter 4, and open a new Jupyter Notebook within this folder. Let's now import our new...
