can pythonista use pickles?

bobsmith76

I was not able to rename the file but I created a new file and cut and paste the text of z_dict_words.py into the newly created z_dict_words.pkl. I then ran the code and pythonista was not able to load the pickle file. This is the error message I got:

File "/private/var/mobile/Containers/Shared/AppGroup/D4D2C25F-316F-47DF-8CFF-84E670A3283D/Pythonista3/Documents/main_loop.py", line 163, in get_result
dictionary = pickle.load(pkl_file)
_pickle.UnpicklingError: invalid load key, '\xc2'.

These lines are 150 - 163 in my code:

def get_result(one_sent, user = "", print_type="40", order=[0], get_words_used=0):
    global words_used
    total_time = time.time()

    if one_sent == 'a':
        proof_type, print_type, get_words_used, order = parameters()
        pkl_file = open(user + 'zz_claims.pkl', 'rb')
        test_sent = pickle.load(pkl_file)
        pkl_file.close()
    elif one_sent != "":
        test_sent = one_sent
    else:
        pkl_file = open(user + 'zz_claims.pkl', 'rb')
        test_sent = pickle.load(pkl_file)
        pkl_file.close()
    pkl_file = open(user + 'z_dict_words.pkl', 'rb')
    dictionary = pickle.load(pkl_file)
    pkl_file.close()

I'm attaching a screenshot so as to demonstrate that the file is in my script library

@bobsmith76 Sorry but I can't help you:I don't know pickle.
Hoping somebody will help you

what about json? can pythonista handle json?

JonB

@bobsmith76 pickles are not text, they are binary. copy/paste from a text file wont work.

json and yaml are good alternatives.
or, just use file import of a zipped pkl.
or, post the file in a gist, or on github, and use stash git or wget to retrieve.

If I import a zipped pkl do I have to unzip it? If so how?

cvp

@bobsmith76 Tap on it and then extract archive

it automatically adds the .py extension to all files. so z_dict_words.pkl becomes z_dict_words.pkl.py. how do i rename files?
