(see Listing 13-5).

Listing 13-5. Loading a Data Structure from a File

>>> shell (1)

2

>>> entry (2)

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

NameError: name 'entry' is not defined

>>> import pickle

>>> with open('entry.pickle', 'rb') as f: (3)

... entry = pickle.load(f) (4)

...

>>> entry (5)
