object-oriented (this is their FIRST proper programming language - they don’t even know how to write loops yet and you want us to teach them OOP at the same time?! And as it turns out, I had one student who literally could NOT work out how to use a loop - kept writing 20 variables for 20 iterations. i.e. her variables never varied!)
variables are weakly-typed (use it for anything, whether it’s what you first used it for or not, Python doesn’t care)
indentation has to be exact (i.e. no brackets, just exact indentation). I had one student whose program wasn’t working, and it even took ME a while to find what was wrong with it (a missing space).
I think there was more, but that’s what I remember off the top of my head. If it was up to me then I would’ve used Pascal - that’s what it’s designed for! But at least C# has strongly-typed variables, and doesn’t care about your indentation (and unfortunately there was no non-OOP language choice available - I’m not sure how this got in the curriculum when every teacher knows you only teach one concept at a time). As I said, many other teachers felt the same way, but couldn’t get it past their school admin’s.
Why do you even have to mention OOP? C# is object oriented too. Would you start explaining OOP too when teaching C#?
Python is comparatively easier as it’s nearly literally pseudo-code. There’s no need to even write a main function or functions at all. It uses less characters too e.g no need for semi-colon, brackets in for loops and if statements
As for indentation being exact, IMO that’s on you. Beginners should be given a proper development environment to work in that helps them as much as possible. Modern editors and IDEs point out syntax errors and indentation errors are incredibly basic. If they are working in an environment that doesn’t even point that out to them, they have been setup incorrectly.
If you’re writing any language in like notepad, you’re going to have a bad time. I accept your point that school administration may be making questionable choices about what software is installed, but that’s not a problem unique to python.
No, but it’s a bigger problem for C# than is is for Python (though this is changing now), so all the U.K.-based schools were teaching Python, rather than the more-appropriate C#. That was my original point - that’s the dumb reason I had to learn Python, school admin’s wanted the lower overhead of the worse language.
Python does have OOP but you are not at all forced to use it. You can write code in a functional or even procedural style.
typing
I do hate that python doesent have proper support for typing but I think weakly typed variables will actually help beginners as it is less to think about to start off with.
indentation
I think there are pros and cons here. In other languages it is considered good style to use indentation anyway.
I’m sure it is difficult to teach a large class like that though. It was hard enough for me to learn with a much more favourable teacher to student ratio than you probably have. Sorry but honestly I do sympathise with admin as well.
have the experience of being the kid in that situation
Which kid? The gifted one, the one who didn’t understand loops and used 20 variables for 20 iterations, the one who didn’t understand how to write pseudo code, the one who was dyslexic,…?
I learnt python in secondary school
Which Year? I didn’t say it wasn’t appropriate for high school, I said it wasn’t appropriate for Year 7 as a first programming language.
Also, who do you mean by “us”? Programmers? Not all the kids in class want to be programmers, and this isn’t a programming class - it’s Computer Science. We cover topics like hardware, the Internet, Cybersecurity, the history of computers, data analytics, etc. Not only do not all of them want to be programmers, not even all of them want to be in I.T. - they’re just, you know, interested in computers (or in some cases they’re in the course because their parents think they should be in it - I’ve had a couple of those students). We only spend 6 weeks on programming (we spend 6 weeks on each topic), or sometimes we might do it twice and spend 12 weeks on it, and that’s it for the year! You can’t teach Year 7 kids algorithms, pseudo code, basic programming concepts (variables, branches, and loops) and OOP as well in one year. Especially when not even all of them are interested in programming. It’s just one topic we cover. OOP is something that shouldn’t be covered until at least Year 8, preferably Year 9 (by which stage students have decided if they want to continue on this path or not, and the ones we still have left we start getting more hard-core… which is where the “us” I presume you’re referring to come in).

Not as an individual, but I’m talking about a situation precisely where the individual choices of teachers are ignored, in some cases by school admins, in some cases by faculty choices. Fortunately I also ran a computing club, in which I was autonomous with how I ran it, and I taught my computing club students C#/MAUI… but even then still saw some of the issues you run into with teaching students. e.g. I told them to install Visual Studio ready for next week, showed them where it was, what workloads to install, and then the next week one of the students had installed Blend for Visual Studio, not Visual Studio. “Look, it has Visual Studio in the name!”. (sigh)
I think weakly typed variables will actually help beginners as it is less to think about to start off with
No, that’s exactly the problem to start with. Another rule of teaching (see below for the full list I’m quoting these from) is “never let the first impression be a wrong one”. If you let students think they can use variables for anything, then you run into problems when they can’t. This is why teaching them with strong types first is better - they learn you need to be careful with how to use them, THEN maybe you can let them have some more freedom like Python allows.
In other languages it is considered good style to use indentation anyway
Yes, but in those languages it’s optional. In Python it’s mandatory, and if someone’s code isn’t working it’s far easier to spot a missing bracket than a missing space.

You can use types in Python and your tools will generate warnings
def something(a: int) -> int: return “potato”
will turn yellow in an IDE more advanced that notepad.
Most editors will also show a red line where the indentation is wrong.
Same thing still applies - you need to get it past the school admin gatekeeper.

It’s odd to me that you’re disagreeing with their actual experience teaching.
Thanks. It’s a very 21st Century phenomenon that I’ve unfortunately run into many times
Lots of us have the experience of being the kid in that situation though. I learnt python in secondary school.
They’ve been through the other side of this experience multiple times though.
