Am I correct assuming that all functions (built-in or user-defined) belong to the same class, but that class doesn't seem to be bound to any variable by default?
How can I check that an object is a function?
I can do this I guess:
def is_function(x):
def tmp()
pass
return type(x) is type(tmp)
It doesn't seem neat, and I'm not even 100% sure it's perfectly correct.

For this, we will use the count() method. The count() method, when invoked on a list, takes the element as input argument and returns the number of times the element is present in the list. For checking if the list contains duplicate elements, we will count the frequency of each element.
The duplicated() method returns a Series with True and False values that describe which rows in the DataFrame are duplicated and not. Use the subset parameter to specify if any columns should not be considered when looking for duplicates.
in python2:
callable(fn)
in python3:
isinstance(fn, collections.Callable)
as Callable is an Abstract Base Class, this is equivalent to:
hasattr(fn, '__call__')
How can I check that an object is a function?
Isn't this same as checking for callables
hasattr(object, '__call__')
and also in python 2.x
callable(object) == True
