Python uses indentation for nested scope (I think that's the right term). While other languages might use curly braces or even keywords like do and end to enclose loops and functions, Python uses indentation. It ensures code is readable, but coding newbies have to learn about whitespace errors AND scoping together. It's one of the parts of the language I dislike the most.
It's weird how python defaults to spaces rather than tabs, as tabs would make indentation errors less prevalent and a lot more obvious to people learning the language.
It's like learning to write but not wanting to learn punctuation. You might end up with the Ulysses but more likely than not you'd end up with something that other people and yourself won't be able to understand well when you look at it on the next day.
That said, I'm in the camp of curly braces (or equivalent) plus an autoindenter. Either a code formatter or the editor itself.
Braces and random indentation is the worst that can happen.
Scoping is essential for general purpose programming, so it is usually fused into the syntax of any GP language in a form of {…} or begin/do…end. Python is one of the languages which try to remove this character and keyword noise based on observation that to see scoping people usually correctly indent their scopes, so python makes indent itself important.
I can recommend using Notepad2 if you want to use GP languages but don’t want to use an IDE (which is understandable as it brings a cognitive overload when you learn). Notepad2 is a drop-in replacement for Notepad, but may be installed as a separate app. It’s not particularly for programming, but has related features that Notepad should have had for ages.
look up a random autohotkey code. you can write it sideways, it will work. you can write it with indentation, it will work. it will work if the whole code is in a single line.
on one hand, it has the least amount of startup for a new programmer because it can teach you to do cool things.
on the other hand, like me, the "habits" get wrong because i never learned to do pretty code.
It's like learning to drive the car whilst sticking to the rules of the road and staying under the speed limit. It's not supposed to be fun.
Besides, I don't know what backwards IDE you used. I've been doing python for 15 years and have never had to manually indent squat, ever.
It sounds more like you didn't actually try python but read about the whitespace indentation somewhere and decided to chime in. Either that or you tried it in notepad.
