Yeah, naming is hard especially when you're trying to be consistent.
In Python everything is an object, a "thing", and those things have "attributes".
- An attribute that holds a value is a variable.
- An attribute that is a function is called a method.
- An attribute that represents a value accessed by getters/setters is call a property.
So a function is an object and a parameter to the function object is, at its core, an attribute. But a class is also an object. And an instance of the class is an object. And operators are objects.
Naming is hard.

I've seen SmallTalk - i think maybe in the late 80s early 90s? Been so long i don't even remember. Never tried it myself.
I'm biased against languages that pretend to be something they're not. I know it's silly of me, but JS and Python with their ersatz OOP (that's not OOP) just leave me with a bad taste in my mouth. I dislike it I think for the same reasons I dislike Turkey-Bacon. Turkey is fine. Bacon is fine. Everything would be fine if they'd just stay in their lane. Objects are fine. Associative arrays are fine. Associative arrays are not objects no matter how many functors you put into them.

This sounds like me ranting that 'invite' is a verb not a noun, and 'alternate' means to switch from one option to another, and is not an alterative.
Damn kids these days...

I think you seem a bit impatient with Python. I find it useful for small quick things. For example string processing or web-scraping. And I do not give a toss whether they call it "object-oriented" or not. Lets call it stuff-oriented or whatevva.
However, on the OO topic... We who are firmly rooted in C++ have a rather strict definition of OO. There are other ways of looking at the term. I warmly recommend this article on the history of OOP (or "OOP"!). The grandfather of the term, Alan Kay, has said among other things:
“I made up the term ‘object-oriented’, and I can tell you I didn’t have C++ in mind.”
“I’m sorry that I long ago coined the term “objects” for this topic because it gets many people to focus on the lesser idea. The big idea is messaging.”

I'm happy with C#'s conception of objects, and even Java's
What I don't like is ersatz objects that are effectively just hashtables keyed by the name of the member.
That sort of construct doesn't fulfill all kinds of object oriented necessities like polymorphism - not that you can't MAKE that work in a language like that, it's just not pretty.
It strikes me as Broken As Designed.

I agree 100% that Python is not elegant from a pure CS point of view. But it is much more concise than C++ and cousins. You have to scroll less (!). We have discussed the benefit of non-scrolling (vs our old brains) in C-code before.
And it does have amazing libraries. I just does the job for small programs. Beyond a few thousand lines, it becomes a nightmare to maintain, mostly due to its total lack of type-safety.

I've discovered a whole new reason to love C# and that is source generators. But also, I've now gotten to the point where my C# CLI apps are as short and succinct as anything similar in python, through the magic of metadata and some code I wrote. Complete with using screens, defaults, etc.
I wrote something to parse a C header file and extract relevant information. From conception to testing to delivery in two hours, about a page and a half of C# code.
Frankly, I agree with Mr. Pfeifer below. I don't need Python, I've got solid tools as it is.
And no goddammned signficant whitespace!**
** funny thing about that.
I actually use minimization in my .NET projects[^]
I do it as part of an alternative to static linking which isn't really available with C#. To save space (sometimes a meg of whitespace!), and to deliberately obscure these files and prevent me from modifying them - rather than modifying the source that they are generated from. I've gotten out of sync before. This keeps me honest.
Python can't do that. In fact, python makes code generation itself a royal pain because of the pigheaded insistence of imposing indents on you.

It's not but for those I have my Program.Base code which makes writing say, a CLI app to wordwrap input files into an output file this easy:
using System;
using System.Collections.Generic;
using System.IO;
internal partial class Program
{
[CmdArg(Ordinal = 0)]
static List<TextReader> Inputs = new List<TextReader>() { Console.In };
[CmdArg(Name = "output")]
static TextWriter Output = Console.Out;
[CmdArg(Name = "width", Description = "The width to wrap. Defaults based on console window size", ItemName = "columns")]
static int Width = (int)Math.Floor((double)Console.WindowWidth / 1.5);
[CmdArg(Name = "ifstale", Description = "Skip if the input file is older than the output file")]
static bool IfStale = false;
static void Run()
{
if (!IfStale || IsStale(Inputs, Output))
{
foreach (var input in Inputs)
{
string line;
while((line = input.ReadLine()) != null)
{
Output.WriteLine(WordWrap(line, Width));
}
}
} else
{
Console.Error.WriteLine("Skipped execution because the inputs did not change");
}
}
}
That parses arguments, presents a using screen, all of that mess. This is how i do "quick things."

Putting my "your programming language wears army shorts", or "Scripting programs aren't programming languages". Biases aside,
I think it can come in handy for one off stuff and quick and dirty test stuff. I am working with some IoT devices that send data to a metered service (cloud). For testing/enhancing (can you say debug?)
I found a quick and dirty script for a python syslog server (yes I have a C## version but it does a bunch of parsing) that just prints what it receives.
import socketserver
class MyUDPHandler(socketserver.BaseRequestHandler):
def handle(self):
print(self.request[0].decode())
with socketserver.UDPServer(('10.0.2.4', 514), MyUDPHandler) as server:
server.serve_forever()
gets:
The temperature in Fahrenheit is:77.9 166
The temperature in Celsius is:25.5
But then, I am the lazy old fool.
Edit: I can run it on my Pi (just got a 5!)

Not really that much harder to do on an ESP32 under Arduino.
And it's $12 w/ a screen included.

Well, to be clear I'm not saying it's either easy or free.
But Arduino does lower the bar for entry into C++ development significantly, even if it's not the best code.
Frankly, RPis are a bit heavy handed, and are priced to match. It's a whole lot more machine than you need for most IoT purposes, and I tend to think of them more as a mini PC than an IoT widget.
The ESP32 has wifi and bluetooth built in, and can do most anything with sensors and such you can do with an RPi, sometimes better, because it's realtime, but without the $100+ price tag, the power consumption, the size, the desk space requirements while coding it, etc.

Maybe not better, but with Python much more easier if I think about all that matrix/vector operations...

Possibly, if my work involved matrix/vector operations. Which it doesn't.

Because the author of the Open Source program I want to modify chose to write it in Python!

Was talking with a friend who leans more network engineer than programmer. They had some programming courses in college.
I'm hoping I convinced them that C#/Powershell are far more useful things to focus on than Python unless they want to shift gears and be a data scientist.
They asked if I thought Python as a first language was a hindrance. I think most absolutely so.
