Added a sentence to the end of the last paragraph

One exception worth noting: in Python versions 1.5.2 and later, be sure
to pass a 'c' as a second argument when calling anydbm.open, to force
Python to create the file if it does not yet exist, and simply open it
otherwise.

First para, changed to

"Since integers are a central datatype, most of the
number operation slots are filled in. In user-defined
numeric types, we can pick and choose operators to
respond to. In Python 1.5 (and later), use NULL pointers
in unimplemented operation slots. Python releases 1.4
and earlier might not detect NULL pointers; instead,
provide pointers to dummy functions for unimplemented
operations."
