Description: The ‘NotImplementedError’ is an exception thrown in object-oriented programming languages when an abstract method that has not been implemented in a derived class is invoked. This type of error is crucial for ensuring that classes inheriting from a base class adhere to the defined interface, forcing developers to provide concrete implementations for abstract methods. The existence of this error helps maintain code integrity and prevents the execution of methods that lack defined logic, which could lead to unexpected behaviors or application failures. In software design terms, the use of abstract methods and the subsequent management of this error are essential for creating robust and maintainable applications. By throwing this exception, the system informs the developer that there is a lack of implementation that needs to be addressed, thus promoting good programming practices and a more structured development process.
