What are the differences between variadic and fixed argument functions?

Can you explain the differences between variadic and fixed argument functions?

Sure! Fixed argument functions require a specific number of arguments, while variadic functions can take a variable number of arguments.

Can you give me an example of each?

Of course! A fixed argument function could be something like def add(a, b): return a + b, which needs exactly two arguments. A variadic function in Python would be def add_all(*args): return sum(args), which can take any number of arguments.

What are the advantages of using variadic functions?

Variadic functions offer flexibility, allowing you to pass any number of arguments without needing to define multiple function signatures.

Are there any downsides to using them?

Yes, one downside is that they can make the code less readable and harder to debug, as the number of arguments isn't fixed.
