Calculating manhattan distance manually

While euclidean distance is very popular, it only scales well beyond two or three-dimensional data. In these cases, you can use manhattan distance as an alternative. It has the advantage of working exceptionally well with datasets with many categorical features.

Practice calculating it manually with NumPy, which has been loaded under its standard alias np.
