Error Handling in Python

This Python program prompts the user for two numbers and performs the division operation. It uses a try..except block to catch potential errors such as dividing by zero. The program first tries to execute the division, and if an error occurs (e.g., dividing by zero), the program catches the exception and displays a clear error message to the user. This approach ensures that the program does not crash and provides a smooth user experience, even in the case of invalid input or mathematical errors. Using exception handling with try..except in Python is a powerful technique for making programs more robust and reliable. This program not only demonstrates how to safely handle errors but also reinforces the importance of validating user input and handling edge cases. By including the try..except structure, the program ensures that the user will be informed of any errors in a clear and controlled manner, making it a great practice for error management in Python programming.

Objective

Develop a Python program to prompt the user for two numbers and display their division. Errors should be caught using "try..except".

Example Python Exercise

 Copy Python Code 
# Prompt the user for two numbers
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))

# Try to perform the division and handle any potential errors
try:
    result = num1 / num2
    print(f"The result of {num1} divided by {num2} is {result}")
except ZeroDivisionError:
    print("Error: Cannot divide by zero.")
except ValueError:
    print("Error: Please enter valid numbers.")

 Output

Case 1:
Enter the first number: 10
Enter the second number: 2
The result of 10.0 divided by 2.0 is 5.0

Case 2:
Enter the first number: ten
Enter the second number: 2
Error: Please enter valid numbers.

Case 3:
Enter the first number: ten
Enter the second number: 2
Error: Please enter valid numbers.
