Python callable()
# Example 1: How callable() works?
# Here, the object x is not callable. And, the object y appears to be callable (but may not be callable).
x = 5

def testFunction():
print("Test")
y = testFunction
print(callable(y))
print("-----------------------------------------------")
# Example 2: Callable Object
# The instance of Foo class appears to be callable (and is callable in this case).
class Foo:

print('Print Something')

class Foo:
def __call__(self):

# The instance of Foo class appears to be callable but it's not callable. The following code will raise an error.
class Foo:
