How to iterate over function arguments

Question

I have a Python function accepting several string arguments def foo(a, b, c): and concatenating them in a string. I want to iterate over all function arguments

Answer 1

def func(*args):
    ' '.join(i if i is not None else '' for i in args)

if you're joining on an empty string, you could just do ''.join(i for i in args if i is not None)
