Polymorphism in Python

When we define abstract methods in base class and each child class implement them for itself, we have one method with various implement this is polymorphism

python

from abc import abstractmethod, ABC
class Stream(ABC):
    @abstractmethod
    def read(self):
        pass
class FileStream(Stream):
    def read(self):
        print("reading from File")
class NetworkStream(Stream):
    def read(self):
        print("reading from Network")
NS = NetworkStream()
FS = FileStream()
NS.read()
FS.read()

Output

reading from Network
reading from File
