python class inherit from parent class that super(SelfClassType, self) __init__ or __class__

#The first is used to initialise newly created object, and receives arguments used to do that:

class Input(object):

def __init__(self, x, y):

self.x = x

self.y = y

print("Input inited x=%d, y=%d" % (self.x, self.y))

def __call__(self, a):

self.x = self.x + a

print(self.x, self.y)

class AInput(Input):

input_type = 'password'

def __init__(self, hide_value=True):

self.hide_value = hide_value

super(AInput, self).__init__(5, 10)

print("AInput inited")

def __call__(self, field):

return super(AInput, self).__call__(field)

a = AInput()# __init__

#The second implements function call operator.

a(2)# __call__
