You can create some really ugly code in spite of the forced indentation in python. Indentation does not really help here at all. In all languages you can correctly or incorrectly format things. A code formatter strictly applying a coding standard helps far more here than indents vs bracers. Take a look at black it takes the pep8 standards and adds more strict things on top making code look a lot more consistent and thus makes it easier to read.
And all formatters will indent code consistently, so having it as part of the language parser does not really help improve readability at all. And even without a formatter everyone I know will still correctly indent their code no matter the language used. But sometimes forcing new lines to have a meaning does make things worst - just look at pythons lambdas which have to be a single line.
