Child object 'str' object is not callable, unable to rectify from other similar posts

I am attempting to create a child object from random variables within a list. I have included all code that I have tried. Googling the errors brings up many posts and solutions, none of which seem to be exactly parallel enough for me to utilize. Thanks for your time and consideration.

import random


class Monster:

    def __init__(self, name, level):
        self.name = name
        self.level = level


class Dragon(Monster):

    def breathe_fire(self):
        print("The Dragon breathes fire!")


class Skeleton(Monster):

    def strikes(self):
        print("The Skeleton strikes with its sword!")


MONSTERS = ["Skeleton", "Dragon"]
monster_type = random.choice(MONSTERS)
monster_level = 1
monster_stats = [monster_type, monster_level]
print(monster_stats)
# create object from child class and pass stats
#monster = random.choice(MONSTERS(*monster_stats)) <--'list' object is not callable
#monster = Dragon(*monster_stats) # <-- works, but is useless for my purposes
#monster = monster_type(*monster_stats)  <---  'str' object is not callable
Solution

  • Try this:

    import random


class Monster:
    name = None

    def __init__(self, level):
        self.level = level


class Dragon(Monster):
    name = "Dragon"

    def attack(self):
        print("The Dragon breathes fire!")


class Skeleton(Monster):
    name = "Skeleton"

    def attack(self):
        print("The Skeleton strikes with its sword!")


MONSTERS = [Skeleton, Dragon]

monster_cls = random.choice(MONSTERS)
monster_level = 1
monster_stats = [monster_level]  # maybe you have other stats too

monster = monster_cls(*monster_stats)

    The main fix is to have a list of classes instead of strings: MONSTERS = [Skeleton, Dragon]
