Peculiar.

$ python
Python 2.7.3 (default, Mar 13 2014, 11:03:55)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from pydoc_data import topics
>>> topics.__file__
'/usr/lib/python2.7/pydoc_data/topics.pyc'
>>> "exec" in topics.topics
False
>>> topics.topics.keys()

Whatever. I've made a few messes on this system, maybe I broke
something somewhere. In any case, help('exec') is what's needed for
help on keywords, even if one particular installation doesn't have one
particular keyword-help.
