Beauty is in the eye of the beholder.  I'm used to the python doc
layout, and I can find my way round it pretty fast. What I like about
it is that it is organised thematically, so it is usually possible to
think your way to where the relevant documentation is.  Moreover,
Python has a very useful help functionality:

* at the interactive prompt:

>>> help(someobject)
>>> help(somemodule)

Will give you lots of useful information

* At the shell prompt:

$ pydoc <keyword>
--> documentation about keyword

It takes time to learn a language, and that includes learning how the
documentation is organised.

The answers are here (in the library reference you checked):
http://docs.python.org/lib/types.html

That's a language feature, so it's in the *language* reference.
http://docs.python.org/ref/summary.html

Because Python is not Javascript?

In fact some are methods, e.g. str(x) is shorthand for x.__str__().
