保存用户输入字典

Question

Im trying to find a suitable method to save a dictionary that has user input data and also data that comes from my program (battleship game). The user input data is player name and the rest is the state of the game (like current game, scores, ...).

I did some searching and tried to use Pickle to save this data. My dictionary is stored here:

def game():
    return {
        'players': [],
        'active_players':[],
        'running_game': False,

Im getting the player data from here:

def player_register(mm,name):
    board1_for_ship_placement = create_grid(columns_size,rows_size)
    board2_for_showing = create_grid(columns_size,rows_size)
    player = {
        'name':name,
        'played_games': 0,
        'victory': 0,
        'ships_available' : {
            "lancha":0,
            "submarino":0,
            "fragata":0,
            "cruzador":0,
            "porta_avioes":0
        },
        'ships_in_use':[],
        'board1': board1_for_ship_placement,
        'board2': board2_for_showing
    }

    mm['players'].append(player)

THIS is the data I need to save and be able to load again on my program. Name , played games and victorys .

This method gathers info from dictionaries.

Now I have seen some examples like this:

import pickle
my_dict = {“example”:”dog”, “example2″:”cat”}
with open(‘myfile.txt’, ‘wb’) as f:
pickle.dump(mydict, f)

Load:

f = open(‘myfile.txt’, ‘rb’)
new_dict = pickle.load(f)
f.close()

Now, how can I modify this to save my data? I have tried this but with no results:

import pickle
**my_dict = game()**
with open(‘myfile.txt’, ‘wb’) as f:
pickle.dump(mydict, f)

Anyone can help me? I doesn't need to by pickle, JSON is also fine.

I added some sample data to the game function and it worked fine. If you don't get the right result, maybe something is wrong with your game function.

Save:

import pickle


def game():
    return {
        'players': ['p1', 'p2'],
        'active_players': ['a_p1', 'a_p2'],
        'running_game': False
    }


my_dict = game()
with open("my_data.pkl", "wb") as f:
    pickle.dump(my_dict, f)

Load:

import pickle

with open("my_data.pkl", "rb") as f:
    my_data = pickle.load(f)

print(my_data)
# Output:
# {'players': ['p1', 'p2'], 'active_players': ['a_p1', 'a_p2'], 'running_game': False}
