def binary_to_decimal(binary_str):
    try:
        decimal_value = int(binary_str, 2)
        return decimal_value
    except ValueError:
        return "Invalid binary input. Please enter a valid binary number."

# Example usage
binary_input = input("Enter a binary number: ")
decimal_output = binary_to_decimal(binary_input)
print(f"The decimal equivalent of binary {binary_input} is {decimal_output}.")

The decimal equivalent of binary 110101011 is 427.
