• Not Working

 

class Friends: def init(self, connections): self.connections = connections self.q = list(connections)

def add(self, connection):
    self.connection = connection
    if connection not in self.q:
        (self.q).append(connection)
        return True
    else: return False

def remove(self, connection):
    self.connection = connection
    if connection in self.q:
        (self.q).remove(connection)
        return True
    else: return False

def names(self):
    k = []
    for x in self.q:
        for i in x:
            if i not in k:
                k.append(i)
    return set(k)

def connected(self, name):
    self.name = name
    k = []
    for s in self.connections:
        if self.name in list(s):
            if list(s)[1] not in k:
                k.append(list(s)[1])

    return set(k)

why connected isn't working ??
