I'm trying to call a function with parameter from a list of list, the problem is that it sees the whole list as one single argument, even though each list in the list of lists contains 3 arguments. How do I get the function to see the list as 3 arguments

lists = [[1, 2, 3], [4, 5, 6], [7, 8, 9], [2, 5, 8]]


def do_something(x, y, z):
    bla. bla. bla

do_something(lists[1])

and the error message says so:

TypeError: do_something() missing 2 required positional arguments: 'y' and 'z'

The function receives 3 arguments x,y,z you are only passing 1. – Dani Mesejo Dec 09 '19 at 09:23
explore the usage of *args, may be this is what you are looking for – anuragal Dec 09 '19 at 09:24

you should call your method like this; do_something(list[1][0], list[1][1], list[1][2]) – Ali Beyit Dec 09 '19 at 09:32
