How can I handle errors in variadic functions?

You can handle errors in variadic functions by checking the number of arguments and validating their types.

Can you give me an example of a variadic function with error handling?

Sure! Here's a simple example in Python:

def safe_sum(*args):
    if not all(isinstance(x, (int, float)) for x in args):
        raise ValueError('All arguments must be numbers.')
    return sum(args)

This function checks if all arguments are numbers before summing them.

What happens if I pass a string to this function?

If you pass a string, the function will raise a ValueError, ensuring that only valid numbers are processed.

Is there a way to handle multiple types of errors?

Yes, you can use try-except blocks to catch different types of exceptions and handle them accordingly.
