NaN vs. NA — understanding Pandas nullable types
Why does Pandas change the dtype when you set something to NaN? What's pd.NA, and how is it different from the traditional np.NaN? And how can we enforce dtypes, rather than have them change automatically?
In this video, I explain what happens in NumPy, how Pandas is different, and how Pandas is changing to use nullable integer and string types. You'll also see how you can take advantage of these new types in your own data projects.
