What keyword is used to indicate an exception in Python?

• A. finally
• B. except
• C. try
• D. raise

Answer: (B)

In Python, the keyword that indicates an exception is "except." It is used within the context of error handling to manage exceptions that occur during the execution of code blocks. When an error or an exception is raised in a try block, the corresponding except block is executed if the exception matches the type specified.

The pattern typically involves using a try block to encapsulate code that may raise an exception, followed by one or more except blocks that define how to handle specific exceptions. This structure allows programmers to create more robust applications that can gracefully handle errors without crashing.

For instance, if you're attempting to convert a user input into an integer and the input is incorrect, you would place the conversion in a try block and handle the ValueError in an except block. This way, the program can continue running or provide useful feedback to the user without terminating unexpectedly.

The other keywords in the choices serve different purposes in exception handling: "finally" is used to define cleanup actions that should be executed regardless of whether an exception occurred or not; "try" is used to start a block of code that will be tested for exceptions; "raise" is used to explicitly trigger an exception in your code. These serve important roles, but the specific keyword for indicating an exception is
