Hi! This might be more of a personal-preference question than anything, but here goes: when is it appropriate for a function to take a list or tuple as input, and when should it allow a varying number of arguments? It seems as though the two are always interchangeable. For a simple example...
def subtract( x, nums ): return x - sum( nums ) ... works equally well if you define it as "subtract( x, *nums )" and put an asterisk in front of any lists/tuples you pass it. I can't think of any situation where you couldn't convert from one form to the other with just a star or a pair of parentheses. Is there a generally accepted convention for which method to use? Is there ever actually a big difference between the two that I'm not seeing? -- http://mail.python.org/mailman/listinfo/python-list
