callable

This callable() function returns a Boolean stating whether the object argument appears callable.

Syntax

callable(object)

Here,

object: Required. Any valid object.

Note: If callable() returns True, it is still possible that a call fails, but if it is False, calling object will never succeed.

Also, note that classes are callable (calling a class returns a new instance); class instances are callable if they have a __call__() method.

Examples

>>> class Class1:
...     pass
... 
>>> def func1():
...     pass
... 
>>> callable(Class1)
True
>>> callable(func1)
True
>>> callable(100)
False
>>> callable('hello')
False
>>> callable(True)
False
