python - Check and update dictionary if key exists doesn't change value

I'm trying to make a terminal-based game. So far, I have a sample class, a default player with default values, and a test file for the checking of updated values. On launch, I want the player default values to be used, but if a save is loaded or new game started, one of the first questions is to set a class, which said class should override the player values FOR THAT FILE/SESSION ONLY. However, after multiple attempts at changing the code, it either throws an error on a random key/pair or doesn't update the value. At one point, it did update the values, but it didn't update properly. Here's my code. from collections import OrderedDict, Counter

player.py

import assets.classes
import random
#import pickle

#begin player data for new slate

class playerSelf:
    def __init__(self):
        #set starter gold variable
        startGold = random.randint(25,215)*2.5
        self.playerStats = Counter({
            'currentHealth': int(100),
            'maxHealth': int(100),
            'stamina': int(10),
            'resil': int(2),
            'armor': int(20),
            'strength': int(15),
            'agility': int(10),
            'criticalChance': int(25),
            'spellPower': int(15),
            'speed': int(5),
            #set gold as random gold determined from before
            'gold': startGold,
            'name': {'first': 'New', 'last': 'Player'},
            'class': None
        })

    def __str__(self):
        return self.playerStats

    def returnStats(self, category):
        category = category.upper()

        if(category == "OFFENSIVE"):
            #print offensive stats
            print("Strength: {}
Agility: {}
Critical Chance: {}
Spell Power: {}".format(self.playerStats['strength'], self.playerStats['agility'], self.playerStats['criticalChance'], self.playerStats['spellPower']))
        elif(category == "DEFENSIVE"):
            #print defensive stats
            print("Health: {}/{}
Stamina: {}
Resilience: {}
Armor: {}
Speed: {}".format(self.playerStats['currentHealth'], self.playerStats['maxHealth'], self.playerStats['stamina'], self.playerStats['resil'], self.playerStats['armor'], self.playerStats['speed']))
        elif(category == "ALL"):
            #print both offensive and defensive stats
            print("Strength: {}
Agility: {}
Critical Chance: {}
Spell Power: {}
Health: {}/{}
Stamina: {}
Resilience: {}
Armor: {}
Speed: {}".format(self.playerStats['strength'], self.playerStats['agility'], self.playerStats['criticalChance'], self.playerStats['spellPower'], self.playerStats['currentHealth'], self.playerStats['maxHealth'], self.playerStats['stamina'], self.playerStats['resil'], self.playerStats['armor'], self.playerStats['speed']))
        else:
            print("Nothing Found.")

    #key function
    def setPath(self, path):
        path = path.upper()
        select = assets.classes.classPath().classDeclare
        chosen = select.get(path, 'That class doesn't exist!')
        if chosen is not 'That class doesn't exist!':
            for key in select[path]['stats']:
                for key2 in self.playerStats:
                    if key in select[path] and key2 in self.playerStats:
                        self.playerStats[key2] = select[path][key]

To give some example of what we mean, I think this is kind of alright

import random
import pickle

class BaseCharacter:

    def __init__(self):
        self.gold = random.randint(25, 215) * 2.5
        self.currentHealth = 100
        self.maxHealth = 100
        self.stamina = 10
        self.resil = 2
        self.armor = 20
        self.strength = 15
        self.agility = 10
        self.criticalChance = 25
        self.spellPower = 15
        self.speed = 5
        # set gold as random gold determined from before
        self.first_name = 'New'
        self.last_name = 'Player'
        self.class_ = None

    def update(self, attrs, factors):
        # Maybe a try except would be nice here
        for attr, fac in zip(attrs, factors):
            val = getattr(self, attr)
            setattr(self, attr, val * fac)

    def show_stats(self):
        for attr in self.__dict__:  # Don't do this... but meh
            print(attr, getattr(self, attr))

    def save(self):
        with open(self.first_name+'_'+self.last_name, 'wb') as f:
            pickle.dump(self, f)

    @staticmethod
    def load(filename):
        with open(filename, 'rb') as f:
            return pickle.load(f)


class WarriorCharacter(BaseCharacter):

    def __init__(self, first_name, last_name):
        super().__init__()
        self.class_ = 'Warrior'
        self.first_name = first_name
        self.last_name = last_name
        self.update(['stamina', 'resil', 'armor'], [1.25, 1.25, 1.35])

w = WarriorCharacter('Jon', 'Snow')
w.show_stats()
w.save()
loadedW = WarriorCharacter.load('Jon_Snow')
print(loadedW.class_)
