How do I make weapons do different amount of damage?

 def attack(self):
    roll = random.randint(1, self.attack_limit)
    weapon_damage = 0
    if self.weapon == 'sword':
      roll += 2
      weapon_damage += 3
    elif self.weapon == 'bow':
      roll += 3 
      weapon_damage += 2
    elif self.weapon == 'axe':
      roll -=1
      weapon_damage += 5
    return roll > 4

def player_turn(self):
    choice = input("Do you want to [A]ttack , [R]est, or [Q]uit?".upper())
    if choice == 'A':
      if self.player.attack():
        print("You are attacking the {}".format(self.monster))
        if self.monster.dodge():
          print("The {} dodged!".format(self.monster))
        else:
          if self.player.leveled_up():
            print("Your hit the {} with two hit points on leveling up!".format(self.monster()))
            self.monster.hit_points -= (2 + self.weapon_damage)
          else:
            self.monster.hit_points -= self.weapon_damage

          print("You hit {} with your {}".format(self.monster, self.player.weapon))  
      else:
        print("You missed!")
    elif choice == 'R':
      print("You are resting")          
      self.player.rest() 
    elif choice == 'Q':
      print("You have decided to flee like the coward you are.") 
      sys.exit()
    else:
      self.player_turn()
