I don't know what is wrong since I told it to save the state of the Player class, but when i load and it displays, it shows the values it would show always.

class Player:
level = 1
player_name = "bob"
health = 100
max_health = 100
damage = 10
gold = 400
pet = ""
experience = 0
defense = 2
weapons = ["Paper Sword"]
items = []
equipped_weapon = ("Rat")
experience_threshhold = 10

my player definition

I my code gets stuck like it was saving and loading at some point, but i don't know what happened, and it stopped, also the manual saving process is bugged as hell, the AskSave() function loops, and load() just ends the game.

Did you mean: `Player = pickle.load(open("Save File","rb"))`? — quamrana, Aug 22 '23 at 14:12
the print statement is printing the function itself rather than printing the result of the function call: you want `Player.display()` rather than `Player.display` — Mouse, Aug 22 '23 at 14:13
Don't do this *pickle.dump(Save, open("Save File", "wb",))* Where/when do you think the file will be closed? — DarkKnight, Aug 22 '23 at 14:22
`Player.display` is a method and you want to print the result of calling it, not the definition of the method — JonSG, Aug 22 '23 at 14:24
@DarkKnight: surely the `file` param of `dump` would release the open file object when `dump()` returns and thus close the file. — quamrana, Aug 22 '23 at 14:25
When I use, Player = pickle.load(open("Save File","rb")) then it gives me the values that the class is set to having always when staring. — Deadmou5, Aug 22 '23 at 14:41
Please update your question with the definition of `Player`. — quamrana, Aug 22 '23 at 14:41
@quamrana I just set Player as a public class and assign values to it, nothing fancy. — Deadmou5, Aug 22 '23 at 14:44
Also, my save file shows all my variables in the class but in binary txt format. — Deadmou5, Aug 22 '23 at 14:47
I think that `pickle` will work better if you create, save and load an *instance* of your `Player` class. Use `player = Player()` first, then `pickle.dump(player, open("Save File", "wb",))` and `player = pickle.load(open("Save File","rb"))` — quamrana, Aug 22 '23 at 14:47
@quamrana i will try that but won.t the load just assign the saved values to the wrong variable? — Deadmou5, Aug 22 '23 at 14:49
I would try it first and get back to me later. I've never used `pickle` as such, but logically it must work this way. `Player` is a `class` defined to have those initial values. A `player` instance picks up those values when created, but when you update them, the `dump(player, ...)` should pick up those updates and write them to disk. Then `load(...)` should be able to re-create the instance. — quamrana, Aug 22 '23 at 14:52
@quamrana didn't work, got some errors for displaying and adding values. — Deadmou5, Aug 22 '23 at 14:55
@quamrana Wouldn't the file handle "dangle" and only be closed when it goes out of scope? I could easily be wrong (I often am). Either way, I don't like that style - but that's just a personal thing — DarkKnight, Aug 22 '23 at 15:03
@DarkKnight Yeah I tried it out and it wasn't it. It does "dangle," along with not even getting me the values from the save into Player. — Deadmou5, Aug 22 '23 at 15:10
@DarkKnight: See my answer. At least on my OS (Windows 10) the file seems to close ok. — quamrana, Aug 22 '23 at 15:13
@DarkKnight: See the answers to this [question](https://stackoverflow.com/questions/57562182/does-a-file-stays-open-if-i-open-it-and-not-assign-it) — quamrana, Aug 22 '23 at 15:19
You are still using `Player. ... = ...`. You should be using `player. ... =` instead. — quamrana, Aug 23 '23 at 18:41
Yes. Generally you don't want a class like yours to be updated. You want instances to be updated like I have in my answer: `player.gold += delta` — quamrana, Aug 25 '23 at 15:10
@quamrana but my code accesses the Player class? How does it still work out? — Deadmou5, Aug 28 '23 at 13:25

I think you are doing it all wrong.

I think the root of the problem is in thinking that your Player is an instance, when it is a class which defines its attributes and initial values. (I suspect that pickle detects that Player is a class and saves and loads it as such).

See this code:

import os, pickle

FILE = 'PlayerPickle.pkl'

class Player:
    level = 1
    player_name = "bob"
    health = 100
    max_health = 100
    damage = 10
    gold = 400
    pet = ""
    experience = 0
    defense = 2
    weapons = ["Paper Sword"]
    items = []
    equipped_weapon = ("Rat")
    experience_threshhold = 10


def load(player):
    if os.path.isfile(FILE):
        return pickle.load(open(FILE,"rb")) #Loads the file
    return player

def save(player):
    pickle.dump(player, open(FILE, "wb",))

def main():
    player = Player()
    player = load(player)
    print(f'Initial Player name {player.player_name}, gold:{player.gold}')
    
    delta = int(input('Enter change in gold: '))
    
    player.gold += delta

    print(f'Current Player name {player.player_name}, gold:{player.gold}')
    
    save(player)

main()

I have used this code to modify the player.gold value and have it stored as a pickle file.

Each time I run the program I get the previous value, which I can update, and I see that new value on the next run.

I did things exactly how you did, made a separate file, and it gives me: TypeError: askSave() missing 1 required positional argument: 'player' — Deadmou5, Aug 22 '23 at 15:19
But your `askSave()` function above takes no parameters. If you have some different code now you should ask a different question. — quamrana, Aug 22 '23 at 15:21
It sounds like your new function takes the `player` parameter. You should call it like this: `askSave(player)` — quamrana, Aug 22 '23 at 15:24
my Player class never gets updated with the player in your code? how would I add that? — Deadmou5, Aug 23 '23 at 14:20

My pickle saving system is saving things but the load won't load anything?
