How to One-Hot encode multiple columns at once in dataFrame using Keras.to_Categorical?

Question

I want to one-hot encode multiple columns in my data frame at once using Keras to_categorical. How to do it?

need_to_encode = ['Item_Fat_Content', 'Outlet_Location_Type', 'Outlet_Type', 'Outlet_Size', 'Item_Type_Combined', 'Outlet']

These are the columns I need to one-hot encode.

Well you could use this util function over every column that needs encoding of your data.

Or you use scikit-learn's categorical encoder on the part of the dataframe you need to encode.

Next time don't forget to include a minimal working example, this way we can help further.
