Topic/Title: Programming with Lambda, Map, Filter & Reduce in Python

Description: There are multiple programming languages in the world with multiple ways they can be classified. A programming paradigm classifies programming languages based on their features or their coding style. Different paradigms (e.g. functional, imperative, object-oriented) describe different styles or modes you can write code in.

Most of the time, Pythons paradigm is seen as object-oriented, a style where we model our data in the form of classes, objects, and methods. But Python supports alternatives to that OOP paradigm - Functional Programming being a very popular choice.
Functions like lambda , filter, map, & reduce fully support the Functional Programming style, and in this live coding session we'll demonstrate how they can be effectively & efficiently used in our data analysis tasks.

Material
If you would like to follow along, it'll be good that they have a Collaboratory Notebook, Jupyter Notebook, or Binder Notebook up and running. I will be live coding from scratch so, this session will be good for everybody who has a basic knowledge of Python.
