you're missing the large part of the language's customers that use it
specifically for experimenting.  they're not developing space
shuttles, but rather explore available data, experiment with
algorithms, etc.  (and for space shuttles, i doubt python is the first
choice anyway.)

yes, i am writing lots of experimental code, and i know many who do,
too, and there is *nothing* wrong about it.  and then, i sometimes use
ipython to interactively experiment, saving the input to a log file,
and editing it afterwards as needed.  and just the mere fact that i
*have* to adapt my editor to ipython's indentation policy (or vice
versa) whenever working with others' code because otherwise the code
fails, is fairly annoying.  there is nothing wrong or stupid about the
editor in this respect.

'proper' formatting is, in some languages, something achieved by
simply running a pretty formatter.  in some, it's the job of the
programmer.  it has nothing to do with the claimed stupidity of the
editor.

you're just wrong.

... and you can't freely format you code with python.

'real'?  meaning one able to guess how to combine code from multiple
developers with different indentation policies, for example, one using
tabs, another four spaces, and yet another eight?  (which is not at
all uncommon, and not quite wrong or stupid.)

'stupid', 'wrong', 'deficient', 'terrible', ...  you're using strong
words instead of concrete arguments, it might intimidate your
opponents, but is hardly helpful in a fair discussion.
