How to Handle ValueError in Python (try except)

Learn to catch ValueError and other exceptions with try-except blocks in Python using practical division and string-to-float conversion examples.

try-except valueerror error-handling
Python
def divide_numbers(a, b):
    """Divide two numbers and handle ValueError safely."""
    try:
        result = a / b
        return f"{a} / {b} = {result}"
    except ZeroDivisionError:
        return "Error: Cannot divide by zero!"
    except TypeError:
        return "Error: Both inputs must be numbers!"
