Duck typing in Python is a concept where the compatibility of an object is determined by the presence of certain methods and properties, rather than the object’s type itself. This allows for more flexible and interchangeable code, as functions can work with any object that implements the required interface. However, it requires developers to ensure that objects conform to expected behavior, often through thorough testing and documentation. Duck typing supports Python’s dynamic and flexible nature but can lead to runtime errors if assumptions about an object’s capabilities are incorrect.
