Haha: "A space breaks everything." Fuck YES! Are you kidding meβ½ It's one of the best features!
Why? Because it's so easy to see. In other languages you've got semicolons which are surprisingly difficult to notice when they're missing. Depending on the situation (or if you're just new to programming) you could spend a great deal of time troubleshooting your code only to find out that you're missing a semicolon. It's frustrating and it makes you feel stupid which is never a good thing for people who are new programming.
Types are in a different category altogether with seemingly infinite reasons why you'd want a feature-rich, low-level type system and also why you'd want to avoid that.
IMHO, the point of Python is to be a simple language that's quick to write yet also very powerful and speedy when you need it to be (by taking advantage of modules written in C or better, Rust). If it had a complex type system I think it would significantly lower the value of the language. Just like how when I see an entire code repo using Pydantic and type hints everywhere it makes the code unnecessarily complex (just use type hints where it matters π).
I'm not saying using type hints on everything is a terrible thing... I just think it makes the code harder to read which, IMHO defeats the point of using Python and adds a TON of complexity to the language.
The promise of type hints is that they'll enable the interpreter to significantly speed up certain things and reduce memory utilization by orders of magnitude at some point in the future. When that happens I'll definitely be reevaluating the situation but right now there doesn't seem to be much point.
For reference, I've been coding in Python for about 18 years now and I've only ever encountered a bug (in production) that would've been prevented by type hints once. It was a long time ago, before I knew better and didn't write unit tests.
These days when I'm working on code that requires type hints (by policy; not actual necessity) it feels like doing situps. Like, do I really need to add a string type hint to a function called,
parse_log()
? LOL!What are you writing your code in? Windows notepad? How the fuck do you not see the semicolon missing?
because semicolons are tiny characters that oftenhave to be appended to the end of lines (precisely the worst place for them to be easily visible, since they'll blend in with the previous character)
whitespace meanwhile is very easy to notice that it's missing, as i'm sure you noticed when reading the above sentence.
In both cases, you press compile and the compiler goes "you missed a whitespace/semicolon HERE"
