Groupby and Sort.

In this challenge, all the operations are independent of the group. There are no special cases based on the group. The complete optimal solution will now be given.

We will use the same definition for our filters as we did in the custom function, but instead calculate them on the entire DataFrame.

This is not the final DataFrame, as some columns can only be calculated from the result of the aggregated values. Optimal Solution In order to greatly increase our performance, we need to take advantage of the built-in methods available to groupby objects.

We just created class named Polynomial that has no any properties and methods right now. After creating polynomials instances, we have set their coefficients.

That's it. Nothing more! But, this is a long procedure right? We just added our first data model that handles initialization and construction of objects.

Summary: Dunder methods are very powerful inbuilt methods in Python which you can use to create advanced classes. This tutorial is an in-depth guide on Python under methods and how to use them with examples.

Python allows you to support your custom objects for inbuilt functions like len , abs , sorted and many others. You just need to implement some special methods dunder methods to your class.

In this tutorial I have used words like dunder methods, special methods and magic methods, all have the same meaning. That is the reason if you see dunder methods or Magic Methods always assume them as Special Methods in Python.

The core data structures also implement these Special methods internally which allow them to be compatible with many inbuilt functions.

To understand this better, here is an example of a Python list. We can easily use len function to find the length of any list but here is an alternative.

Both syntaxes is the same for Python. The reason behind this was to build a common API which other classes can implement to do the same task. This removes the burden to learn methods of each class to do that task.

This is the reason I love Python. I remember the Java days of my coding when I spent most of my time thinking what is the method name to do any specific task.

It was really frustrating. There are very different types of Special methods and they are in large number. It is not possible to explain them all in a single post.

The len() function works with the list, dictionary, tuples and other inbuilt data structures and you can also make your own object compatible with by implementing suitable dunder method (len() in this case).
