How would I change a pickle value for highscore?(python)-CodePudding

I am making a game in python and I want to add a system that saves the users highscore, and loads it the next time the application is run. To do this I am using pickle. I have been able to save the data, but I do not know how to edit the value stored in the pickle file. Code(to show what I want to do):

import pickle
hs=0
savedhs=pickle.dumps(hs)
highscore=pickle.loads(savedhs)
hs=hs 1
print(highscore)
#Expected output: 1
#output:0

How would I make it so that whenever the value of hs changes, the pickled file also changes?

CodePudding user response：

To update the pickled file, you could open it in write mode and update the value. Like this

import pickle

# Open the file in write mode
with open("highscore.pickle", "wb") as f:
    # Load the data from the file
    highscore = pickle.load(f)
    # Update the value of highscore
    highscore  = 1
    # Write the updated value back to the file
    pickle.dump(highscore, f)
