This might do it...

>>> print eval.__doc__
eval(source[, globals[, locals]]) -> value

Evaluate the source in the context of globals and locals.
The source may be a string representing a Python expression
or a code object as returned by compile().
The globals must be a dictionary and locals can be any mappping,
defaulting to the current globals and locals.
If only globals is given, locals defaults to it.
