I'm intrigued that Python has some functional constructions in the language.

It's not that it sucks. More that it's pretty much non-existent.
Yes, many people are very sensitive to such issue -- that is, that
they feel lost without common constructs permeating the code rather
than the fluid and recursive nature of functional programming and its
never-ending flow of userland function calls.
OTOH, I can't help but think part of it has to do with plain text in
your face rather than lots of colorful keywords in your fav editor.

ah, probably. Python has replaced Scheme in certain pedagogical
circles too. Scheme was considered a great tool for teaching basic
compsci concepts *precisely* for it's lack of syntax so that students
could concentrate on the concepts and problems at hand rather than
fight against the compiler or have to learn a huge tome of libs and
frameworks before even outputting a single "hello world".
But Java was all the rage in the past few years at introductory
compsci and at least no doubt Python is a blessing compared to that.
Though it too is not without a lot of quirks itself...

This is a type annotation and there's nothing similar in Python given
it's typeless nature. Should I call Python's non-existent type
annotations horrible too?

def dingle( n, *boz ): return boz[n:-2]
? Sounds perfectly cryptic for the non-initiated too.
