Python SyntaxError: invalid syntax [elif my_move == 'rock']

I’m developing a rock paper scissors on python and I’m getting this syntax error
any help is appreciated

class Player:
def move(self):
    return 'rock'

def learn(self, my_move, their_move):
    self.my_move = my_move
    self.their_move = their_movee here

class Game:
def __init__(self, p1, p2):
    self.p1 = p1
    self.p2 = p2

def play_round(self):
    move1 = input("Pick something!n")
    move2 = self.p2.move()
    print(f"Player 1: {move1}  Player 2: {move2}")
    self.p1.learn(move1, move2)
    self.p2.learn(move2, move1)
    my_score = 0 
    computer_score = 0
    if beats(move1, move2):
        my_score = my_score + 1
        print ("You win")
        print ("Human score = " + str(my_score) + " "  + "Computer score = " + str(computer_score) ) 
    elif beats(move2,move1):
        computer_score = computer_score + 1
        print ("Computer wins")
        print ("Human score = " + str(my_score) + " "  + "Computer score = " + str(computer_score) ) 
    else:
        print ("Draw")
        print ("Human score = " + str(my_score) + " "  + "Computer score = " + str(computer_score) )    

def play_game(self):
    print("Game start!")
    for round in range(3):
        print(f"Round {round}:")
        self.play_round()
    print("Game over!")

class cycleplayer(Player):
def move(self):
    if round == 0 :
        return 'rock'

    elif  self.my_move == 'rock'
        return "paper"   

    elif self.my_move == 'paper'
        return "scissors"  

    else self.my_move == 'scissors'
        return "rock"

on the cycleplayer subclass I want the program to take the previous move and use it in the current round

I get an error on the first elif in the subclass cycleplayer
the error points on "rock"
