   The *source* argument is parsed and evaluated as a Python expression
   (technically speaking, a condition list) using the *globals* and *locals*
   mappings as global and local namespace.  If the *globals* dictionary is
   present and does not contain a value for the key ``__builtins__``, a
   reference to the dictionary of the built-in module:mod:`builtins` is
   inserted under that key before *source* is parsed.  That way you can
   control what builtins are available to the executed code by inserting your
   own ``__builtins__`` dictionary into *globals* before passing it to
 :func:`eval`.  If the *locals* mapping is omitted it defaults to the
   inserted under that key before *source* is parsed.
   Overriding ``__builtins__`` can be used to restrict or change the available
   names, but this is **not** a security mechanism: the executed code can
   still access all builtins.
   If the *locals* mapping is omitted it defaults to the
   *globals* dictionary.  If both mappings are omitted, the source is
   executed with the *globals* and *locals* in the environment where
 :func:`eval` is called.  Note, *eval()* will only have access to the
