Hi Nirav, as suggested, please comment below the topic you are facing the issue in. That way it would be easier for us to understand the context of the query and the issue itself.

In this question, we have 5 features. You need to classify them as Categorical - Ordinal, Categorical - Regular, or as Numerical. However, instead of these strings you can denote them as a, b, and c for these values respectively. The features are indoor temperature as high/low, indoor temperature as values, whether a person has allergy and so on.
