There are two possible wrong things:
1) On Python 2 the module is called __builtin__:
>>> import __builtin__
>>> __builtin__.map
<built-in function map>
2) You've imported the name builtins so that it is available as a name
in the current global namespace. That does not mean that a subsequent
import statement will import from the resulting module object. An
import statement never looks at the names in the current namespace to
find anything. You can however do
import sympy.core.compatbility.builtins as builtins
builtins.type
Or
from sympy.core.compatibility.builtins import type
Not sure what you're aiming for but there is a hacky way to do it:
sys.modules['builtins'] = builtins
