that’s because the self<\/code> variable has to be explicitely given to methods in python. As you write it, are you expecting python to read your mind so it guesses that self<\/code> shall be something from a class your function is not related at all with?<\/p>\n

So to have it bound you need:<\/p>\n

    \n
  1. add self<\/code> to argument list of def pickapoo_specialattack(self, opponent)<\/code><\/li>\n
  2. to move pickapoo_specialattack(opponent)<\/code> in your Deskemon<\/code> class<\/li>\n<\/ol>\n

    looking further in your code, what you’re doing is definitely wrong, as you’re defeating the whole purpose of OOP! Use classes and subclasses to do what you’re aiming. <\/p>\n

    Let me give you an incomplete example of what I mean:<\/p>\n

    class Deskemon(object):\n    def specialattack(self, opponent):\n        raise NotImplementedError\n\n    \u2026\n\nclass Pickapoo(Deskemon):\n    def specialattack(self, opponent):\n         \u2026 # content of the pickapoo_specialattak() function\n\nclass Tamosha(Deskemon):\n    def specialattack(opponent):\n         \u2026 # content of the tamosha_specialattak() function\n<\/code><\/pre>\n
    and then:<\/p>\n
    def main():\n    pickapoo = Pickapoo(\u2026)\n    tamosha = Tamosha(\u2026)\n<\/code><\/pre>\n
    instead of monkey patching<\/strong> Deskemon<\/code> instances, use proper OOP conception and make Deskemon the base class of all your instances. Then you create a specialized instance for each Deskemon<\/code> object, and that’s the thing you initialize.<\/p>\n
    N.B.1: you should init all your objects in a main function:<\/p>\n
    N.B.2: you should place all your code at the end in a main function:<\/p>\n
    def main():\n    # init\n    pickapoo = Pickapoo(\u2026)\n    tamosha = Tamosha(\u2026)\n    lilwilly = Lilwilly(\u2026)\n    bigbboy = Biggboy(\u2026)\n\n    # start up\n    print(\"Welcome to Deskemon Pre-Alpha V1.2\".upper())\n    \u2026\n\n    # play loop\n    while True:\n        deskemon_selection_menu()\n        deskemon_selection_input = input(\"> \")\n        if deskemon_selection_input == \"1\":\n            deskemon = tamosha\n        elif deskemon_selection_input == \"2\":\n            deskemon = pickapoo\n        elif deskemon_selection_input == \"3\":\n            deskemon = lilwilly\n        elif deskemon_selection_input == \"4\":\n            deskemon = biggboi\n        else:\n            continue\n        print(\"You have selected {} as your Deskemon\".upper().format(deskemon))\n        break\n\n    # shut down\n    print(\"Professor Andrew: Alright Jack, it's time to pick your Deskemon.\")\n    \u2026\n    print(\"Jack: OI! \" + name + \"!\")\n    time.sleep(1)\n\n    Battle(deskemon, Jack)\n\nif __name__ == \"__main__\":\n    main()\n<\/code><\/pre>\n<\/p><\/div>\n
