Fix the errors in a computer program or algorithm : Exceptions

The video tutorial discusses the concept of exceptions in programming, particularly in Python. It explains the difference between errors and exceptions, highlighting that exceptions can be handled by programmers. The tutorial covers built-in exception classes in Python and the possibility of creating user-defined exceptions. It emphasizes the importance of robust exception handling in software development to prevent runtime errors from affecting users. The video concludes with a preview of the next lecture on exception handling techniques.

What is the main difference between an error and an exception?

• Errors can be handled by the programmer, exceptions cannot.

• Exceptions can be anticipated and managed by the programmer, errors cannot.

• Errors occur at compile time, exceptions occur at runtime.

• Exceptions are more severe than errors.

What is the base class for all built-in exceptions in Python?

• StandardError

• BaseException

• Exception

• Warning

Why is it important to use predefined exception classes in Python?

• They are faster to execute.

• They are more secure.

• They help handle common errors that are standard to the community.

• They are easier to write.

What is a user-defined exception?

• An error that cannot be handled by the programmer.

• A custom error condition defined by the programmer.

• A built-in error that is commonly encountered.

• An error that occurs during compilation.

What is an example of a common error that requires robust handling in web development?

• Type error

• 404 page not found error

• Memory leak

• Syntax error
