python pickle example

	favorite_color = pickle.load(f)

pickle.load python

import pickle
# load : get the data from file
data = pickle.load(open(file_path, "rb"))
# loads : get the data from var
data = pickle.load(var)

pickle load pickle file

pickle_in = open("dict.pickle","rb")
example_dict = pickle.load(pickle_in)

pickle.dump python

import pickle
# dump : put the data of the object in a file
pickle.dump(obj, open(file_path, "wb"))
# dumps : return the object in bytes
data = pickle.dump(obj)

pickle python

import pickle

python pickle module

# Python3 program to illustrate store 
# efficiently using pickle module 
# 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.

    # initializing data to be stored in db

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