Pickling and Unpickling in python Explained

Pickling allows you to serialize and de-serializing Python object structures. In short, Pickling is a way to convert a python object into a character stream so that this character stream contains all the information necessary to reconstruct the object in another python script.

To successfully reconstruct the object, The Pickled byte stream contains instructions to the unpicker to reconstruct the original object structure along with instruction operands, which help in populating the object structure.

Pickle has two main methods. The first one is a dump, which dumps an object to a file object and the second one is load, which loads an object from a file object.

This function takes three arguments -

So let’s continue to practical:

Below is the example of pickling and unpickling -

To Open the file we used open function, The first argument should be the name of your file and the second argument is wb, wb refers to the writing in binary mode. This means that the data will be written in the form of byte objects.

Here r stands for reading mode and the b stands for binary mode. You'll be reading a binary file.
The output of the Unpickling function is the same as we pickled.

The following data types can be pickled:

The documentation of the Pickle module states:

I hope that you now have a fair understanding of Pickling/Unpickling in python.
