Question

So I am making a python game and I am trying to implement a save/load system. I have the save part down however the load function that I made isn’t working. When I assign cPickle.load to a new list it isn’t registering.

def save():
    file = open('save.txt', 'wb')
    cPickle.dump(GameState, file)
    file.close()

def load():
    inFile = open('save.txt', 'rb')
    newList = cPickle.load(inFile)
    inFile.close()

Please help, thanks!

You probably forgot to return your list in load:

def load():
    inFile = open('save.txt', 'rb')
    newList = cPickle.load(inFile)
    inFile.close()
    return newList

Note that a more Pythonic to load your file is:

def load(name_of_your_saved_file):
    with open(name_of_your_saved_file, 'rb') as inFile:
        newList = cPickle.load(inFile)
    return newList

Here, we use what is called a context in Python (the with...as statement), quite useful to make sure your file is automatically called. It’s also a good idea not to hard-code the name of your file in the function, but pass it as an argument.

When you call your load function, you will get what you put in your pickle, a GameState in your case.

game_state_loaded = load('save.txt')
