Python Exception Handling MCQ

Exception handling in Python is a mechanism that allows you to manage errors or exceptional situations that arise during the execution of a program, rather than letting the program crash. Python provides a way to handle exceptions using the try, except, else, and finally blocks.

try block: Contains code that may raise exceptions.
except block: Handles exceptions raised in the try block.
else block: Executes if no exception occurs in the try block.
finally block: Executes code after try, regardless of exceptions, for cleanup.

You can learn best practices for error handling in Python.

a) Before the try block
b) After the except block
c) After the try block, regardless of exceptions
d) Only when an exception occurs
Answer: c) After the try block, regardless of exceptions

a) try…except
b) try…catch
c) do…catch

3. What is the correct way to handle a KeyError in Python?
a) try…catch
b) try…except
c) if…else
d) try…finally
Answer: b) try…except

Python Lists MCQ
