Python Made Easy

Pickle

The pickle module allows you to serialize Python objects into a binary format and deserialize them back into Python objects. Pickle supports a wide range of Python data types and object hierarchies.

Writing Data

Here below are the methods to write/serialize the data.

First, we need to import the pickle module.

import pickle

Next, we need to open a file. In this example, we want to write the data to the file, so we open it in write binary mode.

my_file = open(“pickleddata.dat”, “wb”)

Let’s say we want to store the following list in a binary file.

data = [1, 2, 3, 4, 5]

To do this, we need to serialise the data then write it to the file. ...
