Python Error Handling (try-except): A Comprehensive Collection of 30+ Multiple Choice Questions
Python is a versatile programming language known for its simplicity and readability. One of the key features that makes Python so popular is its robust error handling mechanism. The try-except block in Python allows developers to catch and handle exceptions gracefully, ensuring that their programs don’t crash unexpectedly.
In this article, we will explore a comprehensive collection of 30+ multiple-choice questions on Python error handling using the try-except block. These questions will cover various aspects of error handling, including syntax, common exceptions, and best practices. So, let’s dive in!

a) try
b) except
c) catch
d) throw
3. What is the syntax for a basic try-except block in Python?

d) Unlimited
7. Which of the following is the correct order of except blocks when handling multiple exceptions?
a) Specific exceptions first, followed by general exceptions
b) General exceptions first, followed by specific exceptions
c) It doesn’t matter, as long as there is at least one except block
d) There is no specific order
8. What is the purpose of the else block in a try-except statement?
a) To handle exceptions
b) To execute code when no exception occurs
c) To ignore exceptions
d) None of the above
9. Which keyword is used to raise an exception manually in Python?
a) raise
b) throw
c) except
d) catch
10. What is the purpose of the finally block in a try-except statement?
a) To handle exceptions
b) To execute code regardless of whether an exception occurs or not
c) To ignore exceptions
d) None of the above
11. Which of the following is NOT a best practice for error handling in Python?
a) Catching and handling specific exceptions
b) Using a single except block to handle all exceptions
c) Providing meaningful error messages
d) Logging exceptions for debugging purposes
12. How can you handle multiple exceptions in a single except block?
a) By separating them with commas
b) By using multiple except statements
c) By using a tuple of exceptions
d) It is not possible to handle multiple exceptions in a single except block
13. What is the output of the following code?

except ZeroDivisionError:
print(“Zero Division Error”)
except:
print(“Unknown Error”)
a) Zero Division Error
b) Unknown Error
c) Zero Division Error followed by Unknown Error

except ValueError:
print(“Value Error”)
except:
print(“Unknown Error”)
a) Value Error
b) Unknown Error
c) Value Error followed by Unknown Error
d) The program crashes
15. What is the output of the following code?
try:
print(10 / 2)
except ZeroDivisionError:
print(“Zero Division Error”)
finally:
print(“Finally block”)
a) Zero Division Error
b) Finally block
c) Zero Division Error followed by Finally block
d) Finally block followed by Zero Division Error
These are just a few examples of the multiple-choice questions that can be asked about Python error handling using the try-except block. By answering these questions, you can test your knowledge and understanding of this important aspect of Python programming.
Remember, error handling is crucial for writing robust and reliable code. It allows you to gracefully handle unexpected situations and provide meaningful feedback to users. So, make sure to practice and master the art of error handling in Python!
