what should be done in order to execute it
class parent():
age=None
name=None
def __init__(self,name,age):
self.name=name
self.age=age
def printout(self):
print(self.name)
print(self.age)
class child(parent):
def __init__(self,name,age,gender):
super(parent,self).__init__(self.name,self.age)
print gender
c=child("xyz",22,"male")
c.printout()
I am a newbie in the world of python, unable to figure out what is the problem
super() only works for new-style classes; add object to the base classes for parent:
class parent(object):
You may want to adjust your super() call as well. You need to give the current class, not the parent class to start searching from, and self.name and self.age are still set to None by the time your __init__ is called, but you seem to want to pass on the name and age arguments:
def __init__(self, name, age, gender):
super(child, self).__init__(name, age)
print gender
With these changes, the code works:
>>> c = child("xyz", 22, "male")
male
>>> c.printout()
xyz
22
super() works for new style classes only (In Python3, everything is new style). SO you need
class parent(object):
Also in call to super, the first argument is the name of the child class not the parent class. The call in child class should be
super(child, self).__init__(name, age)
You need to inherit from object to make super() work, also self.name and self.age are always None when you pass them to the super() call.
class parent(object):
And:
super(child, self).__init__(name, age)
