The *expression* argument is parsed and evaluated as a Python expression
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 *expression* is parsed. That way you can
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
*globals* dictionary. If both mappings are omitted, the expression is
*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
:term:`nested scopes <nested scope>` (non-locals) in the enclosing
