The documentation describes them by showing equivalent generator
functions and there may be a pure Python version of the module but if
you look here then you can see which are builtin for CPython:

http://hg.python.org/cpython/file/c3656dca65e7/Modules/itertoolsmodule.c#l4070

The list covers all of the documented itertools functions (actually I
now realise that they're mostly types not functions).
