I think this is sufficient for a shallow copy.
import copy
import types
def copyfunction(func):
new = types.FunctionType(
func.__code__,
func.__globals__,
func.__name__,
func.__defaults__,
func.__closure__
)
vars(new).update(vars(func))
new.__annotations__.update(func.__annotations__)
if func.__kwdefaults__ is not None:
new.__kwdefaults__ = func.__kwdefaults__.copy()
return new
