This can be a failure of the language or or your ears.

When you write Pascal, Modula, Oberon or Delphi (what
I did for years), you are used to it and will probably
like it. When you write C or C++, the braces will
be not that bad after some time.

That's for sure one of the reasons to omit them
for Python :-)

Whowwwww! What a nice concept. Maybe you should
invent a new language? You might think of a very
new name, something like "Visual Basic"?

How do you define "best" in a person independant manner?

The lead bracket is the keyword itself, and the end
bracked is obvious by indentation and no longer
necessary. If you want to waste one line, use #endif.
This feature was added to Python long time ago and isn't
very well known. Python is so flexible that you even
can choose anything behind the "#".

Bill Gates would kiss you for this :-)

If you like Python, you will like indentation. Indentation
belongs to Python like Python belongs to Guido.
