#take almost any Python object (even some forms of Python code!), and convert it to a
#string representation; this process is called pickling.
# Reconstructing the object from the string representation is called unpickling.
# Between pickling and unpickling, the string representing the object may have been
# stored in a file or data, or sent over a network connection to some distant machine.
#If you have an object x, and a file object f that's been opened for writing, the
#simplest way to pickle the object takes only one line of code:
f = open('/tmp/workfile', 'r+')
pickle.dump(x, f)
f.close()
