callable()

a=5
x="hi"
my_list=['One','Two','Three']
print(callable(a)) # False
print(callable(x)) # False
print(callable(my_list)) # False 

class student_kit():
    #instance attributes
    def __init__(self,name):
        self.name= name
        
Alex=student_kit('Alex')  # object declaration
print(callable(student_kit)) # True
print(callable(Alex)) # False , object is not callable
#Alex()   # this will generate error 

TypeError: 'student_kit' object is not callable

Example 1: Checking Callable Objects

def my_function():
    print("Hello")
print(callable(my_function))  # Output: True

Example 2: Callable vs Non-Callable Objects

x = 5
print(callable(x))  # Output: False

Example 3: Checking Callable Methods Inside a Class

class MyClass:
    def method(self):
        print("This is a method.")
        
obj = MyClass()
print(callable(obj.method))  # Output: True
print(callable(obj))         # Output: False

Example 4: Callable Classes

class CallableClass:
    def __call__(self):
        print("This class instance is callable.")
        
obj = CallableClass()
print(callable(obj))  # Output: True

Example 5: Non-Callable Built-in Objects

string = "Hello"
print(callable(string))  # Output: False
