# In this example we will see how to use pickle module for storing the data efficiently!

# The pickle module translates an in-memory Python object into a serialized byte stream—a string of bytes

# that can be written to any file-like object.

import pickle

def storeData():

# initializing data to be stored in db

Omkar = {'key' : 'Omkar', 'name' : 'Omkar Pathak', 'age' : 21, 'pay' : 40000}

Jagdish = {'key' : 'Jagdish', 'name' : 'Jagdish Pathak', 'age' : 50, 'pay' : 50000}

# database

db = {}

db['Omkar'] = Omkar

db['Jagdish'] = Jagdish

dbfile = open('examplePickle', 'ab') # Its important to use binary mode

pickle.dump(db, dbfile) # source, destination

dbfile.close()

def loadData():

dbfile = open('examplePickle', 'rb') # for reading also binary mode is important

db = pickle.load(dbfile)

for keys in db:

print(keys,'=>',db[keys])

dbfile.close()
