py.checkio -The Ship Teams

You have to divide all your crew members into 2 teams with the next rules: those who are elder than 40 y.o. or younger than 20, should be on the first ship and all the others - on the second. 

Precondition:
1 <= amount of the sailors <= 100

 

def two_teams(sailors):
    ll = [[],[]]
    for k in sorted(sailors):
        v = sailors[k]
        if v > 40 or v <20 :
            ll[0].append(k)
        else:
            ll[1].append(k)        
    return ll
