Fix the errors in a computer program or algorithm : Errors and Exceptions

The video tutorial explains how to handle exceptions in Python using try-except blocks. It covers the importance of catching errors to prevent program crashes, especially when dealing with user input. The tutorial demonstrates handling zero division and key errors, and explains the try-except-finally structure. It also addresses type errors that occur when adding integers and strings, emphasizing the need for error handling to ensure smooth program execution.

What is the primary purpose of using a try-except block in Python?

• To execute code faster

• To avoid using loops

• To handle errors gracefully

• To make code more readable

Why are errors inevitable when dealing with user input?

• Because users always input numbers

• Because user input is always a number

• Because user input is always a string

• Because users never make mistakes

Which of the following is NOT a keyword used in exception handling in Python?

• except

• try

• catch

• finally

What happens when a ZeroDivisionError occurs in a try block?

• The program continues without any issues

• The program crashes immediately

• The except block is executed

• The finally block is skipped

In the context of exception handling, what is the role of the 'finally' block?

• It executes only if there is an error

• It executes only if there is no error

• It always executes regardless of errors

• It never executes

What type of error occurs when trying to add an integer and a string?

• ValueError

• TypeError

• KeyError

• ZeroDivisionError

How can you ensure a program continues running even after encountering an error?

• By using a return statement

• By using a print statement

• By using a loop

• By using a try-except block
