Unless we compare with what we have now, which gives 9 (without space) or 10

That is not a significant enough savings to create new syntax.
Well, 9 characters is probably significant enough saving to create new syntax
but saving these characters is only a side effect and is not the most important
aspect of this proposal which leads us to the next point.
Remember the Python philosophy that there ought to be one way to do it.
Funny you use this argument against my idea as this idea comes from following
this rule whereas getattr goes against it. Using dot is the main syntax to
access attributes. Following this, the syntax I'm proposing is much more in
line with this primary syntax than getattr is. If there ought to be only one
way to access attributes then it should be dot notation.
I believe that you are missing the point of getattr. It's not there so
that one can use arbitrary strings as attribute names; it's there so
that one can get attributes with names that aren't known until run time.
For this purpose the dot-notation-with-quotes you suggest above is not
good enough. For suppose e.g. that one does this:
name = 'attribute'
x.name
How would the interpreter know whether you're asking for getattr(x,
name) or getattr(x, 'name')?
