4,119 Pointslist functions doesn't need unpacking?
in the vid the sample code for def add(nums) needed the "" when it's for packing tuple:
def add(*nums): ... total = 0 ... for num in nums: ... total += num ... return total ... add(5,5) 10
however when i used list entries i found out that you don't need to use * in the add():
def add(nums): ... total = 0 ... for num in nums: ... total += num ... return total ... add([5,20]) 25
why is that?

231,275 PointsYou only need the "splat" operator when the function will be passed several individual arguments and you want to treat them as a list in the function body.
If the function is passed an actual list as a single argument, you don't need it.
