I started learning Python 2 weeks ago, and now I am trying to code a text adventure game. However, I've run into a problem. So far, I haven't found any solution on Google which can help me.
I decided to store basically all relevant variables in dictionaries - feel free to tell me wether that's even a clever idea or rather stupid of me, I actually do not know this, I just thought it might be a solution that works.
Here's my problem: last thing I decided to insert into the program is a save_game()
function. So I defined:
def save_game(data):
import shelve
savegame = shelve.open('./save/savegame')
savegame['data'] = data
savegame.close()
And of course, if I then call
save_game(save_game_data)
with save_game_data
being the dictionary where I've put all the other dictionaries so I can handle saving with a single function call (I thought that might be better?), it actually works.
But of course a save_game()
only makes sense if you can also reload the data into the program.
So I defined:
def load_game(data):
import shelve, time
savegame = shelve.open('./save/savegame')
data = savegame['data']
data = dict(data) # This was inserted because I hoped it would solve my problem, but it doesn't
savegame.close()
But the result of
load_game(save_game_data)
Unfortunately is no updated dictionary save_game_data
with all the keys and values, and I just can't get my head around how to get all the stored data back into values in the dictionaries. Maybe I'm on a totally wrong way all together, maybe I just don't know enough about Python yet to even know where I'm erring.
The save_game()
and load_game()
functions are in a different file from the main file, and are correctly imported if that is relevant.
CodePudding user response:
It looks like you're trying to pass save_game_data
to load_game()
as if to mean "load data and put it into save_game_data
" but this isn't what load_game()
is doing. By doing this:
def load_game(data):
import shelve, time
savegame = shelve.open('./save/savegame')
data = (savegame['data'])
You're replacing what data
refers to, so save_game_data
doesn't get changed.
Instead, you can drop the argument to load_game()
and add:
return data
at the end of the function, and call it like this:
save_game_data = load_game()
