Sure enough, that does look simple, but imagine how many lines would you have to re-write when in a real-life situation? This poses more issues than you might think up of. Imagine you had to copy and paste the same line of code for more than 20 classes you defined further into your program. In the end, you find out you had some values wrong in the start. This means, the rest will now need to be changed individually as well. Why go through such hard work? Instead let’s see how inheritance can help us out here.

We begin by first creating a parent class. Since cars and bikes are modes for transportation, we will create a class called ‘Transport’ to begin the process. Once done, we simply move the entire block of code we were interested in, right inside this new class. It should now look like this:

class Transport:

def speed(self):

print("Fast")
