Total questions: 13
Worksheet time: 7mins
Why Use Error Handling? Error handling ensures that your program can handle unexpected situations without crashing, helping improve user experience and program stability.
To improve user experience and program stability
To make the program run slower
To increase the complexity of the code
To reduce the need for testing
Error Handling is:
a process of responding to the occurrence of exceptions during computation
a method to increase the speed of a program
a technique to optimize memory usage
a way to enhance the user interface
What are Exceptions?
A type of error handling mechanism
A type of loop
A type of variable
A type of function
Throwing Exceptions: When a program encounters an error condition, it "throws" an exception. This is like the program signaling that something went wrong and needs to be addressed.
True
False
Catching Exceptions: When an exception is thrown, it can be "caught" by the program. This prevents the program from crashing and allows you to handle the error in a controlled way. In Python, this is done using the try and except blocks.
True
False
Finally Block: The finally block is a piece of code that runs after the try-except block, no matter whether an exception was thrown or caught. It is typically used for cleanup operations (like closing files or freeing resources).
True
False
What is the purpose of the Try Block in Python?
To handle exceptions
To write code that might raise an exception
To execute cleanup code
What does the Except Block do in Python?
It runs code that should execute no matter what
It is used to catch and handle specific exceptions
It writes code that might raise an exception
The purpose of the Finally Block in Python is to:
Execute code regardless of whether an exception is raised or not.
Handle exceptions that are not caught by except blocks.
Terminate the program immediately when an exception occurs.
Log error messages to a file.
The suspicious code is put inside the
Try Block
Finally Block
Else Block
Except Block
The unexpected event happened during program execution should be handled by
EXCEPTION
EXPERIMENT
ASSERTION
EXTRAORDINARY
Exception disrupts the
Normal flow of the program
Abnornal flow of the program
Hard Disk
None of the Above
What happens if an exception is thrown in a function, but not caught?
The program continues executing and it is ignored.
The function that throws the exception is exited.
The program terminates.
The compiler will find the error and the program would not compile.
