for loops are the bread and butter of imperative programming and Python has some really nice tools to work with them. If you want to traverse several structures in parallel, have you considered using zip?

A waiter at a restaurant gets a group's order completely wrong. Can you turn the table to get two or more orders right?

Structural pattern matching is coming in Python 3.10 and the previous Pydon't explored some interesting use cases for the new match statement. This article explores situations for which match isn't the answer.

In the fourth article of this short series we will apply our neural network framework to recognise handwritten digits.

Structural pattern matching is coming in Python 3.10 and this article explores how to use it to write Pythonic code, showing the best use cases for the match statement.

A bunch of ants are left inside a very, very, tight tube, and they keep colliding with each other and turning around. How long will it take them to escape?

The third article of this short series concerns itself with the implementation of the backpropagation algorithm, the usual choice of algorithm used to enable a neural network to learn.

In the second article of this short series we will create a class for a generic neural network and we will also see how to assess the quality of the output of a network, essentially preparing ourselves to implement the backpropagation algorithm.

Python's comparisons operators can be chained to shorten common comparison expressions. Learn the ins and outs of comparison operator chaining and especially the cases you should avoid, namely those where you chain comparison operators that aren't aligned.

This is the first post in a series to implement a neural network from scratch. We will set things up in terms of software to install, knowledge we need, and some code to serve as backbone for the remainder of the series.
