2. I thought I'd be happy with * / + -, etc. Of course now I want to add
a few more funcs like int() and sin(). How would I do that?
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, {})
Thanks. That was easy :)
The change to the _ast version is left as an exercise to the reader ;)
And I have absolutely no idea on how to do this. I can't even find the
_ast import file on my system. I'm assuming that the _ast definitions
are buried in the C part of python, but that is just a silly guess.
