$ echo 'from typing import NamedTuple; NamedTuple("A")' \| ./python -m ast Module( body=[ ImportFrom( module='typing', names=[ alias(name='NamedTuple')], level=0), Expr( value=Call( func=Name(id='NamedTuple', ctx=Load()), args=[ Constant(value='A')], keywords=[]))], type_ignores=[]) So mod.body[-1].value is a call: Call(func=Name(id='NamedTuple', ctx=Load()), args=[Constant(value='A')], keywords=[]) I do not know what Astroid does with this node, but seem the problem is in its infer() method.

$ echo 'from typing import NamedTuple; NamedTuple("A")' | ./python -m ast
Module(

      ImportFrom(

            args=[
               Constant(value='A')],
            keywords=[]))],
   type_ignores=[])

So mod.body[-1].value is a call:

    Call(func=Name(id='NamedTuple', ctx=Load()), args=[Constant(value='A')], keywords=[])
