Encoding categorical variables - one-hot

One of the columns in the volunteer dataset, category_desc, gives category descriptions for the volunteer opportunities listed. Because it is a categorical variable with more than two categories, we need to use one-hot encoding to transform this column numerically. Use pandas' pd.get_dummies() function to do so.

Call get_dummies() on the volunteer["category_desc"] column to create the encoded columns and assign it to category_enc.
Print out the .head() of the category_enc variable to take a look at the encoded columns.
