i have a game wich was programmed on python 2 apparently, and i need to change it to python 3 code style, im a begginer on this so there's a lot i don't know, so far the only thing i could change was the prints wich only needed parenthesis. My current problem is the following:

File "A:DescargasGalacticWarsGalacticWarsgalacticWars.py", line 984, in <module>

main()

File "A:DescargasGalacticWarsGalacticWarsgalacticWars.py", line 979, in main

escena.update()

File "A:DescargasGalacticWarsGalacticWarsgalacticWars.py", line 102, in update

funcion()

File "A:DescargasGalacticWarsGalacticWarsgalacticWars.py", line 150, in nuevo_juego

escena = Game()

File "A:DescargasGalacticWarsGalacticWarsgalacticWars.py", line 554, in __init__

  self.record = pickle.load(self.records)

TypeError: a bytes-like object is required, not 'str'

The lines have this:

984 and 985

if __name__ == "__main__":

main()

976 to 981

# Bucle principal.

while True:

    # Actualizamos la escena.

    escena.update()

    escena.imprimir(screen)

    clock.tick(60)

89 to 102:

    def update(self):

    # Altera la opción seleccionada con las teclas cursor.

    key = pygame.key.get_pressed()



    if not self.mantiene_pulsado:

        if key[K_UP]:

            self.seleccionado -= 1

        elif key[K_DOWN]:

            self.seleccionado += 1

        elif key[K_RETURN]:

            # Invoca a la función asociada a la opción-

            titulo, funcion = self.opciones[self.seleccionado]

            print 'Selecionando función:', repr(titulo)

            funcion()

146 to 150:

# Función para comenzar el nuevo juego.

def nuevo_juego():

# Pasamos la variable global escena.

global escena

escena = Game()

552 to 556:

# Vamos a otener el Hi-score.

    self.records = open('records', 'r')

    self.record = pickle.load(self.records)

    self.records.close()

    print 'Cargando Record:', self.record

python 2's str is of type "bytes".
python 3's str is of type "unicode".

the short, irresponsible answer would be:

change self.records = open('records', 'r')

to self.records = open('records', 'rb')

the long, responsible answer would be:

read about the topic and handle it in a way which would be proper for ALL your code
