I got the same error message but i can't find the mistake in my code. Need some help!

import random
from combat import Combat

class Character(Combat):
  attack_limit = 10
  experience = 0 
  base_hit_points = 10

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

  def get_weapon(self):
    weapon_choice = input("Weapon ([S]word, [A]xe, [B]ow): ").lower()

    if weapon_choice in 'sab':
      if weapon_choice == 's':
        return 'sword'
      if weapon_choice == 'a':
        return 'axe'
      else:
        return 'bow'
    else:
      return self.get_weapon()

  def __init__(self, **kwargs):
    self.name = input("Name: ")
    self.wapon = self.get_weapon()

    for key, value in kwargs.items():
      setattr(self, key, value)
