You can disagree, as much as you want. You don't get to define my
experience. Maybe all those things you enumerate are all easy, all
taken together they can makes it cumbersome at times.

But why should I have to do all that. When I write other code I just
don't have to bother and it is all indented as desired too.

Again why should I have to bother. Why does python force me to go
through all this trouble when other languages allow themselves to
be happily edited without all this.

I'll decide how to layout my code.

I didn't like it at first, accustomed to it a bit and then disliked it
again. So no I don't think I will grow to love it. Python is a tool,
not a religion, so I can live with it if the tool I use has some
featurese I dislike about it. As long as I evaluate the usefulness of
the tool as positive I can live with the peeves.

What is more annoying are the people with some kind of need to reason
your peeves away, as if it is sacriledge daring to dislike something
about the language.
