Option 1: As they say in the classics, "Suck it and see".
If you want to find out if something is supported, just type it in:
>>> somecode = '3+4'
>>> eval(somecode)
7
>>>
Option 2: Use help():
>>> help(eval)
Help on built-in function eval in module __builtin__:
eval(...)
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.
Option 3: If you have Windows, it's easy to find, just click on the
Python documentation icon, then select the index tab, and type in "eval"
(or whatever).
Option 4: On the Python website, click on the docs link, then choose
library reference manual, then either go to the built-in functions, or
go to the index and select "eval" -- this latter method will take you to
