如何检测字典是否具有特定条件？

Question

I'm trying to implement a save feature into my game to save a variety of information. The save part works perfectly fine, but the load part does not work. This is my current dictionary:

player_data = {'x':x, 'y':y, 'world':mapSection, 'introcomplete':homeintro}

I am loading/saving with this:

def save_game():
    with open("savegame", "wb") as f:
        pickle.dump(player_data, f)
def load_game():
    with open("savegame", "rb") as f:
        global player_data
        player_data = pickle.load(f)

And to see what mapSection is set as, I use this:

load_game()
print(player_data)
if "1_1" in player_data:
    print('maploaded')
    game_map_1_1()
else:
    print('reset')
    game_intro()

But for some reason, it always skips over the if statement to the else statement. I don't know what I am doing wrong.

Answer 1

I'm guessing what you really want to do is check player_data['world'] == '1_1' and not '1_1' in player_data . The second one checks if you have a key named 1_1 .

This is not specific to pickle.
