I've published a framework for doing SQL-like programming in Pure Python -- no database required.

Here: https://github.com/slott56/functional-SQL. See the functional-SQL documentation.

This allows us to transform SQL:

SELECT n.name, v.c2
FROM names_table n, values_table v
WHERE n.code = v.c1

To pure Python:

Select(name …

I saw a confusing post on https://fosstodon.org.

I won't link to it, but I will quote it because it repeats some common misconceptions.

I have some iterator chain (in reality longer and more complex than this example).
And now in one or more steps, I need to add …

This was a surprising thing (for me) to see. Surprising because -- after writing a book about functional programming, I'd forgotten that some of the ideas are actually really new to people.

(I've omitted the source of the quote because I want to reuse this without worrying about link rot. Some …

I'm undecided if this goes into the next book. Maybe this is a teaser... And yes, this is a Python to the Rescue story.

I live on a boat. See Red Ranger Blog for details. What's essential is this little complication.

The lock keeps …

Here's a functional programming design pattern I uncovered. This may not be news to you, but it was a surprise to me. It cropped up when looking at something that needs parallelization to reduced the elapsed run time.

Consider this data collection process.

for h in some_high_level_collection(arg1):
    for l …

https://sobolevn.me/2019/02/python-exceptions-considered-an-antipattern While eloquent and thorough, I remain unconvinced that this is a significant improvement over try/except. It's common enough in some functional languages to have strong support and a long, successful history. I think it replaces one problem with another. It's not a "solution …

Real Quote (lightly edited to remove tangential nonsense.)

Recently, I watched a video and it stated that OO is about nouns and Functional programming is about the verbs. Also, ... Aspect-Oriented Programming with the e Verification Language by David Robinson

It would be nice to have a blog post which summarized …

See Goodbye, Object Oriented Programming. I don't want to say that the entire article is bunk. It's not. It raises a few good points. Points which I thought were pretty well known. What's aggravating is that this lamentation is overly broad. It treats all languages as if they're Java or …

Someone found Yet Another Post (YAP™) insisting that the Gang of Four (GOF™) patterns were on their last legs. The email was misleading, because this is not precisely what the article said. The bottom-line was that Design Patterns in general are merely a response to gaps in the underlying programming …
