Working with pickle. How to output all dictionary data from a file?

Question

Python

How to output all dictionary data from a file? The code:

import pickle
f = open('users.txt', 'rb')

e = pickle.load(f)

pickle.load(f) outputs only one line. Tried like:

import pickle
f = open('users.txt', 'rb')
e = pickle.load(f)

while e.keys() != '':
    print(pickle.load(f))

Here the program outputs all lines except the last one. Instead of the last error EOFError
What to do?

Answer 1

Try like this:

from pickle import dumps, load


def store(arg):
    f = open('file.txt', 'w')
    f.write(dumps(arg))
    f.close()


def extract():
    f = open('file.txt', 'r')
    result = load(f)
    f.close()
    return result


d0 = {'one': 1, 'two': 2}
store(d0)
d1 = extract()
print d1

It also shows the difference between dump/load and dumps/loads. By the way, Python 2.7.
