Please someone adds an Option Explicit to Python.
The fact that something like this is even conceivable, let alone valid, is atrocious:
class Empty:
pass
Empty.completelyNewAttribute = "seriously?"
obj = Empty()
obj.randomTypo = 10
Every new programmer makes fun of C++ for being unnecessarily hard to use but I think that a language like Python, with all the possible ways it enables programmers to shoot themselves, is 10 times harder than C++.
And yes, my opinion that Python is VB with different clothes is only becoming stronger. Ugh.

when I see code statements like goto and option explicit, I run in the opposite direction.

I honestly think that is the objective (thinning the herd).

What is funny about this is that most of the software these "new programmers" run, was written partly or mostly in C++. Inconceivable!

I like the way you think. I work in embedded so the my particular herd is already very thin

Goto is an issue. Option Explicit is the programmer telling you how they're handling variables.
|
|
|
|
|

Would you rather see an option explicit or wonder what the result of
var sum = "6" + 6
is?
Option explicit prevents the confusion.

You do understand that Python was named in honour of "Monty Python's Flying Circus" (where chaos and madness were the norm)?

That's what I keep telling people, especially when I see the logo of 2 intertwined snakes.

I tried it for a few weeks but found it extremely hard to understand. I'll stick with C++ and Java.

There are some slightly weird things you need to get your head round. Once you 'get' those things it really is quite an easy language to use.

It's quirky. As I'm more and more convinced, it's VisualBasic all over again (they do share birth year, by the way). It's useful to automate random stuff, it's single thread, it has a strong support for binary calling and a nice quick graphic interface whose logic is 1:1 that of Windows.
In my company we will probably start using Python for automated testing and data analysis so we will need to learn it; I do find myself in need of a quick GUI to link to my Serial / MODBUS / LIN libraries to prod and test our products; we also have a self improvement program that makes us choose courses to follow during the year.
Given all of the above, the decent multiplatformity (is that even a word?) of Python and its ubiquity it makes for me a good choice.

Once you realize that objects are just dictionaries, and everything is an object, it all makes a lot more sense, but one does have to understand that there is a difference between an object's dictionary and an object's instance dictionary.

That's the big gotcha indeed, it takes a while. Also scopes are dictionaries, everything is public, every line of code is executed, every method is static... and an object.

Remember when people complained about C, so someone came up with lint?
Guess what?
pylint.org ๐

Lint... the only tool that can take a perfectly readable piece of code and make a total mess out of it. I wonder what damages it can do with Python.

I think what you're looking for are __slots__
class Empty:
__slots__ = ('completelyNewAttribute',)
Empty.completelyNewAttribute = "seriously?"
obj = Empty()
obj.randomTypo = 10

No! It is about the right tool for the job.I love C++, Java, SQL and Python but all of them require different ways of thinking and is for solving different problems. If you approach Python like C++ it will frustrate you to no end.
However, for the right problem Python is an absolute blast to use! If you need to get something done quickly, with lots of uncertainty and you have the opportunity to iterate Python is amazing. I love it when you can work with an interface/dataset which you only need a small portion of and you don't have to define and type the stuff you are not interested (which happens a LOT in the data world). Of course lots of people hate that uncertainty and would love for everything they work with to be 100% defined, but defining something 100% of which you only use 10% is literally a waste of time.
Of course that depends on context. If you deal with transactional banking you want everything defined 100% and I will stick to Java/C++. If you are trying to extract value from an enterprise data lake quickly where you don't know all the data, will have no opportunity to know all the data then using Python for ML and other purposes is awesome.

Of course. I loved VB6 for its intended use and it had the following nigthmares
Option Base 1
Option Compare Text
Option Explicit
On Error Resume Next
Dim variable as Variant
I know where it comes from and what it is meant to do, I think it is awesome with its extensive standard library. I need it to automate stuff and talk to libraries while showing a minimal UI for expert users. So, the same as VB but portable and still maintained.

These days it feels like C# has taken one look at Python and said to the guy next to him: "hold my beer..."

Nahh, that is the fun stuff. When I was doing my first foray into this language I just could not stop giggling, since I could almost imagine Pinky and Brain kinda talking about adding this feature here, that feature over there and how coooool would it be to have feature in their language like that.
Anyway, python is great for prototyping AI algos and building\training models. I also heard that web guys do it with quality.But since I use it for my diploma with AI stuff in it, I only saw how well you can use it to build AI stuff with it.

This is not intended as a political statement.
