In particular, what this is really revealing is that a Perl associative
array is really represented as a list, with each successive pair
representing a key and a value.  (When writing list and associative
array literals, you see the same thing.)

This goes back to Perl's weakly-typed approach to everything.  Since
Python is not weakly typed, emulating this behavior is not only not
convenient, but is not even advisable.
