suggestion - getting unique vlaues

https://learn.365datascience.com/courses/data-preprocessing-numpy/striping-values-from-ndarrays

Regarding Jupyter notebook output 158
there was no "method/step" given for getting the 6 possibilities in the second column.

I tried,
l_uniq = set(lending_co_total_price[:,1])
l_uniq

The mehtod used by you may look more professional and not a quick and dirty trick. Would appreciate if that is included whenever this video is updated.

Just a suggestion.
Thank you.
Regards.
