How to initialize a list containing instances from another class?

I'm trying to learn OOP and I can't find out how to initialize a list containing atributes initialized in another class.

class Player:

def __init__(self,name,skill_index):
    self.name=name
    self.skill_index=skill_index


class Team:

def __init__(self, playerlist):
    self.playerlist='''Here I need to init a list of instances from Player class'''
    return(playerlist)

So if I call it by print(Team([Player("Player1", [2, 3]), Player("Player2", [3, 1]])) what should I write after self.playerlist= to get the list? Very sorry for poor explanation, I'm a beginner.

Completing what you have already coded:

...
class Team:
    def __init__(self, playerlist):
        self.playerlist=playerlist

team = Team([Player("Player1", [2, 3])])
player = team.playerlist[0]
print(player.skill_index)
>> [2, 3]

To access members of a list, the position is used, starting from 0: some_list[position]. Just remember: __init__ shall not return ever and everything is an object in Python, also lists; you can access properties of an element in a list by using the . notation or getattr built-in method.

UPDATE: to know the length of an iterable object use len()
