Testing if an object is a function

[Claus Tondering]

If I want to test if an object, x, is an integer, I can call
isinstance(x, int).

But what do I do if I want to test if x is a function?

I can do this:

if isinstance(x, type(lambda: None)): ...

But it does not seem very elegant to me.

Surely there is a simpler way to specify a type object that is the type
of a function.

if callable(x):
...

(if you really want a function object, and not anything that's likely to be possible
to call, see the "types" module)
