Re: How to call the super class instance variables in sub class in python3

[daniel main]

Use the super() builtin function. It returns an object that has the ability
to instantiate your parent class. see  sample code:

class Animal(object):
def __init__(self,*args,**kwargs):
pass
 #print(types,'Base class with Animal')
class Mammal(Animal):
   def __init__(self):
   super().__init__('Child classs for mammal')
   print('Child Class for mammal')

m = Mammal()

The output:
usr/bin/python3.6 /home/bug/PycharmProjects/pydummies/graphics/one.py
Child Class for mammal

Process finished with exit code 0
Thanks.
