Python script engine

[Dave Kuhlman]

The built-in function exec will do this for you (or use eval, if
it's a expression).

But exec is dangerous, because it enables your users to do anything
that Python can do.  If this is too much power, then look at
'rexec' (Restricted execution framework) in the Python standard
library.

And, if _you_ want to implement the commands that your users
execute, then take a look at 'cmd' (Support for line-oriented
command interpreters) in the Python standard library.

Also, if you want users to enter and execute Python code
interactively, then I believe you will want to look at 'code'
(Interpreter base classes) in the Python standard library.  You
will find an example of it's use in Tools/idle in the Python source
code distribution.
