EXERCISE 131 : Use exception handling in python program

Objectives

At the end of this exercise you shall be able to
• develop python program for exception handling.

Procedure

Exception handling in Python is done using the try, except, else, and finally blocks. Here are five examples
demonstrating different use cases for exception handling
TASK 1: Division by Zero

# Example 1: Division by Zero
try:
numerator=int(input(“Enter the numerator: “))
denominator=int(input(“Enter the denominator: “))
result=numerator/denominator

exceptZeroDivisionError:
print(“Error: Division by zero is not allowed.”)
else:
print(f”Result: {result}”)

finally:
print(“This block always executes, regardless of exceptions.”)
Explanation:
• We use try to enclose the code that might raise an exception.
• except Zero Division Error catches the specific exception if the denominator is zero.

• else block executes if there are no exceptions.
• finally block always executes, regardless of whether there is an exception or not.
