id() tells you nothing about the nature of the function. Use the
inspect.isbuiltin():
>>> import bisect
>>> bisect.bisect
<built-in function bisect>
>>> import inspect
>>> def foo(): pass
...
>>> inspect.isbuiltin(foo)
False
>>> inspect.isbuiltin(bisect.bisect)
True
It's perhaps a bit poorly named, but "builtin" functions are those not
written in Python. That is, those written in C or C++.
