So far we have written functions that use a single monad. We will now see how we can combine the functionality of multiple monads. To do this, let us revisit the API sequencing problem. The API Sequencing Problem As before, we want to determine the country of a person by
After that small discussion on Y Combinator, we are back to monads! In the previous article on monads, we saw how we can use the the Result monad to chain a sequence of API calls together while automatically handling any failures along the way. In this article we will learn
It's time to take a break from practical applications of functional programming to something less practical, but very interesting to know 😎
A common requirement is to call various APIs in a sequence, any of which may fail. We see how to implement this requirement in a clean way using monads.
If you have been following this site, you will know that we are currently developing a video course on building robust python applications using pytest to do test driven development. We recently completed a small video demonstrating how to clean up an ugly set of if-else conditionals by refactoring it
In this exercise we are going to solve a variation of the robot kata. This version is called the Lost Robot kata.
After PyCon US 2022, it's time for another big python conference: EuroPython. As before, we are live tweeting threads on the different sessions from the conference. All those tweets are collected on this page. Enjoy!
Monads have a reputation as being a very complicated aspect of functional programming. In this article we demystify them and learn how to apply monads in our code
Here we implement the robot kata in a functional programming style
We just released a video showing how to use PyScript to build a Tic Tac Toe game from scratch in just 10 minutes.
