Python classes provide all the standard features of object oriented programming,the class inheritance mechanism allows multiple base classes,a derived class can override any methods of its base class and a method can call the method of a base class with the same name.The following syntax of python class.
class ClassName: <statement-1> . . . <statement-N>
Class object support two kinds of operations - attribute references and instantiation.attribute references use the standard syntax used for all attribute references in python - obj.name.Valid attribute names are all the names that were in the class’s namespace when the class object was created. So, if the class definition looked like this.
class MyClass: a = 10 def f(self): return 'Welcome'
class Fruit(object): """A class that makes various tasty fruits.""" def __init__(self, name, color, flavor, poisonous): self.name = name self.color = color self.flavor = flavor self.poisonous = poisonous def description(self): print "I'm a %s %s and I taste %s." % (self.color, self.name, self.flavor) def is_edible(self): if not self.poisonous: print "Yep! I'm edible." else: print "Don't eat me! I am super poisonous." lemon = Fruit("lemon", "yellow", "sour", False) lemon.description() lemon.is_edible()
I'm a yellow lemon and I taste sour. Yep! I'm edible. None
