why can python not read my pickle file code example

Example 1: pickle load pickle file

pickle_in = open("dict.pickle","rb")
example_dict = pickle.load(pickle_in)

Example 2: save a file as a pickle

with open('mypickle.pickle', 'wb') as f:
    pickle.dump(some_obj, f)

# note that this will overwrite any existing file
# in the current working directory called 'mypickle.pickle'
