Build a neural network in 9 lines of code

You must have heard about deep learning once and you might felt curious about how to implement deep learning. The first thing that comes to me is a Neural Network whenever I hear the word deep learning. Now, what is a neural network, and what is deep learning? Let's understand a little about them and then without taking much time, we will build our Neural network in just 9 lines of code. Personally, I call it The Hello World of Deep Learning with Neural Networks.
