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.

  3247

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.

  2471

Does elegance matter when writing computer programs..?

  1424

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

  5057

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.

  2028

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.

  3653

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.

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.

  2256

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

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.

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

In this article we use (finite state) automatons to count 698,438,863,898,480,640 passwords in a couple milliseconds.

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

  3883

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.

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

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 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.

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.
