Python is duck-typed, even in its documentation. If Python describes
something as a function, it means it can be used in place of func in
result = func(arg1, arg2, arg3)
It might be something created with def (a "classic" function). It
might be something created with lambda. It might be an object with a
__call__ method. It might be a type.
>>> class foo:
return lambda: print("asdf")
How many functions are defined here?
