 Help with Classes and dictionaries
#1
Hello, I'm am trying to convert my old game engine into a newer version that uses classes instead of just dictionaries.

My goal is to add similar key values together from two different classes in order to modify stats of the player.

class player:
    def __init__(self, name, level, xp, nextlvlxp, stats, inventory):
        self.name = ''
        self.level = 1
        self.xp = 0
        self.nextlvlxp = 25
        self.stats = {
            'str': [],
            'dex': [],
            'con': [],
            'int': [],
            'wis': [],
            'cha': [],
            'modstr': [],
            'moddex': [],
            'modcon': [],
            'modint': [],
            'modwis': [],
            'modcha': []
        }
        self.combat_stats = {
            'totalhp': [],
            'currenthp':[],
            'totalmp': [],
            'currentmp': [],
            'baseatk': [],
            'attack': [],
            'speed': [],
            'perception':[]
            
        }
        self.noncombat_stats = {
            'evasion': [],
        }
        self.inventory = {}


class Item():
    def __init__(self, name, description, stats, value):
        self.name = name
        self.description = description
        self.stats = {}
        self.value = value
class Weapon(Item):
    def __init__(self, name, description, stats, value):
        self.stats = stats
        super().__init__(name, description, value)
 
    def __str__(self):
        return "{}\n=====\n{}\nValue: {}\nStats: {}".format(self.name, self.description, self.value, self.stats)
 
class Sword(Weapon):
    def __init__(self):
        super().__init__(name="Sword",
                         description="A common shortsword",
                         stats = {
                             'str': 2,
                             'dex': 1
                         },
                         value = 10)
Example:items 'sword' 'str' + player 'str' = player 'modstr'

I want to be able to add those together and also the next values for dex, I want to do this in a way that is nonrepetitive. I'm not really sure where to begin, I just barely learned how classes to write Classes today. Is there any way to go through the dictionary and add values together that have the same key?

a = {1: 2, 3: 4, 5: 6}
b = {1: 8, 3: 2, 7: 8}

for key in a:
    if key in b:
        a[key] += b[key]
That's basically what you would do, however I'm not sure in your case, since your default attributes are empty lists.

Wow, this is exactly what I needed, and it also shows me how much more I have to learn just to become a beginner at this, lol. Time to study this and break it down so I can maybe figure out how classes work and how i can learn to manipulate them, too.
