how to create class python code example

Example 1: how to make a class in python

dog1 = Dog("Spot")
dog1.walk()
dog1.bark()
cat1 = Cat("Juniper")
cat1.walk()
cat1.meow()

Example 3: python define class

  def __init__(self):
    pass
  def something(self):
    pass
xx = uneclasse()

Example 4: class python

class MyClass(object):
  def __init__(self, x):
    self.x = x

Example 5: what is an object in python

Example 6: class python

class A:        # define your class A
.....

class B:         # define your class B
.....

class C(A, B):   # subclass of A and B
  
obj = C() #to create instance
# issubclass(sub, sup) boolean function returns true if the given 
# subclass sub is indeed a subclass of the superclass sup

# isinstance(obj, Class) boolean function returns true if obj is an 
# instance of class Class or is an instance of a subclass of Class
