Python Pickle/UnPickle Serialize/DeSerialize

#Python pickle module is used for serializing and de-serializing a Python objects.
#Any object in Python can be pickled so that it can be saved on disk.
#Pickling “serializes” the object first before writing it to file.
#Pickling will convert a python object into a character stream.


#Serializing - pickle
import pickle
emp = {"employees":[
    {"name":"Shyam", "email":"shyam@mail.com"},
    {"name":"Bob", "email":"bob32@mail.com"},
    {"name":"Jai", "email":"jai87@mail.com"}
]}
pickling_on = open("Emp.pickle","wb")
pickle.dump(emp, pickling_on)
pickling_on.close()


#De-Serializing - unpickle
pickle_off = open("Emp.pickle","rb")
emp = pickle.load(pickle_off)
print(emp)


#Output
{'employees': [{'name': 'Shyam', 'email': 'shyam@mail.com'}, {'name': 'Bob', 'email': 'bob32@mail.com'}, {'name': 'Jai', 'email': 'jai87@mail.com'}]}
