EOFError Ran out of input Python

Question

I am trying to use pickle to create a save file for my game, but When I try to submit my dictionary, and then take that information back, but it isn't working.

import pickle
data = {'health':100, 'gold':1560, 'name': 'mariano'}
with open('s.txt','wb') as f:
    pickle.dump(data, f, protocol = 2)

with open('s.txt','rb') as f:
    data = pickle.load(f)

then when I run that code it gives me this error

EOFError: Ran out of input

Answer 1

I figured out what went wrong, or at least how I fixed the situation. You were trying to use a file that was already pickled, and since it ran with an error it broke it, all you have to do is change the name of the file.

Answer 2

I was having a similar issue. My code looked like this:

h = open("my_file.pkl", "wb")
pickle.dump(my_data, h)

That was within a cell in a Jupyter notebook. When trying to load my_file.pkl later I'd get EOFError: Ran out of input.

I believe the cause of the error was the file handler h wasn't getting closed, meaning the file didn't save correctly. Changing it to this fixed the problem:

with open("my_file.pkl", "wb") as h:
    pickle.dump(my_data, h)
