Origins of Python's "Functional" Features
I have never considered Python to be heavily influenced by functional languages, no matter what people say or think. I was much more familiar with imperative languages such as C and Algol 68 and although I had made functions first-class objects, I didn't view Python as a functional programming language. However, earlier on, it was clear that users wanted to do much more with lists and functions. A
A practical introduction to functional programming
Many functional programming articles teach abstract functional techniques. That is, composition, pipelining, higher order functions. This one is different. It shows examples of imperative, unfunctional code that people write every day and translates these examples to a functional style. The first section of the article takes short, data transforming loops and translates them into functional maps a
Good With Computers
In this series we take an in-depth look at transducers. Transducers - a portmanteau of "transform reducers" - are a new functional programming concept introduced into the Clojure programming language. Although transducers are actually pretty straightforward in retrospect, wrapping your brain around them, especially if you're not already a competent Clojureist, can be challenging. In this series, w
Python exceptions considered an anti-pattern
What are exceptions? Judging by their name it is an entity representing some exceptional situation that happens inside your program. You might be wondering how do exceptions are an anti-pattern and how does this relate to typing at all? Well, let’s find out! Problems with exceptions First, we have to prove that exceptions have drawbacks. Well, it is usually hard to find “issues†in things you use
