Python Polymorphism (Duck Typing) Program

This program helps you to learn the fundamental structure and syntax of Python programming.

Try This Code
# Program to demonstrate polymorphism via duck typing

class FileLogger:
    def write(self, message):
        print("[File]", message)


class ConsoleLogger:
    def write(self, message):
        print("[Console]", message)


def log_something(logger):
    logger.write("Logging an event")


log_something(FileLogger())
log_something(ConsoleLogger())
Output
[File] Logging an event
[Console] Logging an event

Understanding Polymorphism (Duck Typing)

The function 'log_something' relies only on the presence of a 'write' method, not on concrete types.

Note: To write and run Python programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Python Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Python programs.
