Well, it certainly isn't agile without batteries.

No, agile describes the language. It's easy to get things done *with*
Python. You're asking whether the Python-dev development process of getting
packages added to the standard library is agile. It absolutely is not, and
that is by design: python-dev doesn't want to fill the std lib up with
unnecessary, unused and buggy batteries just because one or two people
request them.

The process for getting modules added to the std lib is on the Python
website.

http://www.python.org/dev/peps/pep-0002/

If you have a library you want added, go right ahead and make a PEP.

Says who? Batteries can be small, and adding a few new batteries to the pile
doesn't necessarily make the pile significantly bigger.

Small means it doesn't have unnecessary batteries.

Would be a toy.

No no no, the std lib needs to be conservative, so that if you write code
that relies on the std lib, you can be confident that it will work
anywhere. The core language and std library are conservative, slowly
changing, so that developers have stability. You don't have to write code
like this:

if version == 2.5:
    code block
elif version == 2.5.1b:
    different code block
elif version == 2.5.1:
    still different code block
elif version == 2.5.2:
    if exists(module):
        code block
    else:
        something different again
elif version == 2.5.3:
     ...


If you want to live on the bleeding edge, with rapidly changing APIs and
libraries, they have a repository for that. It's called "the Internet".
