##### Naming matters | Pydon't 🐍

In this Pydon't you'll learn the importance of using good names and I'll give some tips to help you.

##### Neural networks fundamentals with Python – student-teacher

In this article of the NNFwP series we'll do the “student-teacher” experiment with two neural networks, where one network will learn directly from the other.

##### Code style matters | Pydon't 🐍

In this Pydon't I talk about Python style and I go over some tools you can use to help you remain within a consistent style.

##### Bite-sized refactoring | Pydon't 🐍

In this Pydon't I show you why refactoring is important and show you how to do it in little steps, so that it doesn't become too overwhelming.

##### Does elegance matter? | Pydon't 🐍

Does elegance matter when writing computer programs..?

##### __name__ dunder attribute | Pydon't 🐍

This Pydon't walks you through the usages of the __name__ dunder method and how to use it effectively.

##### Usages of underscore | Pydon't 🐍

The purpose of this Pydon't is to show you what underscores are used for in Python, and to show you how to write more idiomatic code with them.

##### The power of reduce | Pydon't 🐍

In this Pydon't we will take a look at the reduce function, which used to be a built-in function and is currently in the functools module.

##### Boolean short-circuiting | Pydon't 🐍

In this Pydon't we explore what Boolean short-circuiting for the and and or operators is, and how to use this functionality to write more expressive code.

##### Inner workings of sequence slicing | Pydon't 🐍

In this Pydon't we conclude the slicing trilogy and take a look at the inner workings of Python slicing, from the built-in slice type to the dunder method __getitem__ and its siblings.

##### Mastering sequence slicing | Pydon't 🐍

In this Pydon't we cover advanced topics related to sequence slicing, like (negative) steps, more idiomatic sequence slicing, slice assignment, and slice deletion.

##### Neural networks fundamentals with Python – subtleties

In the fifth article of this short series we will be handling some subtleties that we overlooked in our experiment to classify handwritten digits from the MNIST dataset.

##### Idiomatic sequence slicing | Pydon't 🐍

This article covers the basics of sequence slicing in Python and teaches you some idiomatic slicing patterns to write more elegant code.

##### Sequence indexing | Pydon't 🐍

A short article with all you need to know about sequence indexing in Python – and a bit more.

##### Enumerate me | Pydon't 🐍

If you need to access the items of an iterable but also keep track of their indices, have you considered using enumerate? Let's talk about another of Python's amazing tools to work with for loops.

##### Let's build a simple interpreter for APL - part 4

In part 4 of this series we add some unit testing, improve our tokenizer and implement the primitives ⍴ and ⍤.

##### Zip up | Pydon't 🐍

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?

##### Structural pattern matching anti-patterns | Pydon't 🐍

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.

##### Neural networks fundamentals with Python – MNIST

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