How to handle ValueError?

You can handle a ValueError in Python using a try and except block. This allows you to catch the exception and take appropriate action, such as printing an error message or providing a fallback value. Here’s an example:

try:
    string_number = "abc"  # This will cause a ValueError
    integer_value = int(string_number)
except ValueError:
    print("Invalid input! Please enter a valid number.")

In this example, if the conversion of string_number to an integer fails and raises a ValueError, the program will catch the exception and print an error message instead of crashing. You can also handle multiple exceptions in the same try block if needed.
