Defining base classes

We will now start building the code required for the case study.

Let’s start by developing a metaclass named CarSpecs. This class will have the following structure:

1. The __new__ of the CarSpecs class will perform the following tasks:
   1. If the attribute of the input class is an integer, then add the attribute name in title case as feature, the value in string format as info, and type as numeric.
   2. If the attribute of the input class is a string, then add the attribute name in title case as feature, the value in string format as info, and type as varchar.
   3. If the attribute of the input class is a Boolean, then add the attribute name title case as a feature, the value in string format as info, and type as Boolean.
   4. If not, the actual attribute will be returned as such.

Let’s now look at the definition of CarSpecs:

from abc import ABC, abstractmethod
class CarSpecs(type):
    def __new__(classitself, classname, baseclasses...
