Evidence to the contrary:

* Heterogeneity of object abstractions: in order of complexity, you use namedtuples, classes, and metaclasses. In Lisp you'd use the same kind of abstraction across complexity levels.

* Similarly, there are lambdas, plain functions, and bound methods, all for pretty much the same thing.

* Which do you use when? How hard is it to change? http://lukeplant.me.uk/blog/posts/djangos-cbvs-were-a-mistak...

* The way so many configuration variables in Django are strings, that just "coincidentally" point to a class, module, or function.

I've been using Python for 10 years, and Django since pre-1.0. My current startup is built on it. The parts start to show.

Actually, what I like about Python frameworks is that they don't look like DSLs, they manage to be clean, explicit, casual and understandable Python code, even if you may consider them a DSL at a conceptual level.
