YAML sucks because, among other things, indenting it is not obvious.
In contrast, the only mistake of Python when it comes to whitespaces was allowing hard tabs, which makes it too easy to mix them if your editor is not configured.
Improper indentation stands out more than missing or unbalanced braces and it's really not an issue to delimit code blocks.
Hard tabs are the only accessible option though. If you care about developers with a different vision capability than yours, the only correct indentation choice is tabs.
If, because of bad vision, someone needs to crank the font size way up, it’s very possible that they might need to work with a tabstop of 3, 2, or even just 1 space.
With tabs, this is user configurable. With spaces it isn’t.
In any modern editor it is configurable with spaces too
What “it” is configurable? If the code is indented with 4 spaces, it is indented with 4 spaces. You can configure your editor to indent with 1 space if you want, but then your code is not going to respect the 4 spaces of indentation used by the rest of the code.
I repeat, the only accessible indentation option is using tabs. This is not an opinion because every other option forces extra painful steps for those with vision issues (including, but not limited to, having to reformat the source files to tabs so they can work on them and then reformat them back to using spaces in order to commit them)
