For the builtin eval, just populate the globals dict with the names
you want to make available:
import math
globs = {'__builtins__' : None}
# expose selected builtins
for name in 'True False int float round abs divmod'.split():
globs[name] = eval(name)
# expose selected math constants and functions
for name in 'e pi sqrt exp log ceil floor sin cos tan'.split():
globs[name] = getattr(math,name)
return eval(s, globs, {})
The change to the _ast version is left as an exercise to the reader ;)
