#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()- unpickle the object，unpickleobject,#To unpickle
