FAQs on User Defined Exceptions In Python Programming Video Lecture - Crash Course for EmSAT Achieve

1. What are user-defined exceptions in Python programming?
Ans. User-defined exceptions in Python programming are exceptions that are created by the user to handle specific error conditions that may occur during the execution of a program. These exceptions allow the programmer to define their own custom error messages and actions to be taken when a particular error occurs.
2. How can we create a user-defined exception in Python?
Ans. To create a user-defined exception in Python, we need to define a new class that inherits from the built-in Exception class. This new class can have its own custom error message and can override the methods of the Exception class to define specific actions to be taken when the exception is raised.
3. Why would we use user-defined exceptions in Python programming?
Ans. User-defined exceptions are used in Python programming to handle specific error conditions that may occur in a program. By creating custom exceptions, programmers can provide more meaningful error messages and define specific actions to be taken when those errors occur. This helps in improving the overall error handling and debugging process of the program.
4. Can we raise multiple user-defined exceptions in a single program?
Ans. Yes, we can raise multiple user-defined exceptions in a single program. Python allows programmers to define as many custom exceptions as needed to handle different error scenarios. By raising multiple exceptions, programmers can handle a wide range of error conditions and provide specific error messages and actions for each case.
5. How do user-defined exceptions help in making Python programs more robust?
Ans. User-defined exceptions play a crucial role in making Python programs more robust by providing better error handling capabilities. By creating custom exceptions, programmers can catch specific error conditions and take appropriate actions, such as displaying relevant error messages, logging errors, or retrying failed operations. This helps in improving the program's resilience and makes it easier to identify and resolve issues during the development and testing phases.
