Python Program to Differentiate Between type and isinstance

#BackCoding

Let's understand the difference between type() and instance()
we see that type() cannot distinguish whether an instance of a class is somehow related to the base class. In our case, although obj_triangle is an instance of child class Triangle, it is inherited from the base class Polygon. If you want to relate the object of a child class with the base class, you can achieve this with instance().

#python3

[BackCoding]

class Polygon:
def sides_no(self):
pass

class Triangle(Polygon):
def area(self):
pass

obj_polygon=Polygon()
obj_triangle=Triangle ()


print(type(obj_polygon)== Polygon)

print(isinstance(obj_polygon, Polygon))
print(isinstance(obj_triangle, Polygon))
