Example:

import pickle

d1 = {}

d1['name'] = 'kuldeep'

d1['school'] = 'sjsu'

d1['city'] = 'san jose'

d1['id'] = 252666

print "before pickling \n",d1

#PICKLING

f1 = open("pickled_data", "wb")

pickle.dump(d1, f1)

f1.close()

#UNPICKLING

f1 =open("pickled_data", "rb")

d1 = pickle.load(f1)

f1.close()

print "after pickling \n", d1

-------------------------------------------------------------------

output:

before pickling 

{'city': 'san jose', 'school': 'sjsu', 'name': 'kuldeep', 'id': 252666}

after pickling 

{'city': 'san jose', 'school': 'sjsu', 'name': 'kuldeep', 'id': 252666}
