What will be covered in this Blog

1. What is Zip files?
2. How to Unzip a File Using Python

Let's get started!

What is Zip file?:

The Dictionary Definition:

ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed.

Zip files can come handy for a lot different things, we make use of it on a regular basis.

Uses for Zip File:

  • Zip files help you to put all related files in one place.
  • Zip files help to reduce the data size.
  • Zip files transfer faster than the individual file over many connections.

If you wish to know more about it, you can refer to Zip file Wikipedia Page).

Module Used:

ZipFile Module:

ZipFile module provides tools to create, read, write, append, and list a ZIP file. Any advanced use of this module will require an understanding of the format, as defined in PKZIP Application Note.

If you wish to know more about it, you can refer to ZipFile Module Documentation.

Now that you are familiar with Zip file use cases and have acquired basic knowledge of ZipFile module, we can move forward to the coding section.

Time to Code!

In order to access the Python library, we need to import the package in our Python script.

import zipfile as z

We will make use of zipfile module to Unzip the file. Now that we have imported the package in our python script, let's start by defining the target zipped file.

target = 'demo.zip'

demo.zip is the zip file we are targeting to Unzip. Let's display a start message.

print('Starting to Unzip the File!')

Let's make use of ZipFile method from zipfile and pass in our target file. I am storing it in root

root = z.ZipFile(target)

Once done, let's define our destination details. We will make use of extractall method for the same.

If the folder with name new already exists, it will create an unzipped file inside it. Otherwise, a new folder will be created with the given name.

What if NO parameter is passed?

Well, in that case, a new folder will be created with name same as the zipped file name i.e. demo.

#CASE 1:
# Destination folder exist with name 'dest'


#CASE 2:
# Create a new Destination folder at the time of Script execution


#CASE 3:
# No parameter is Passed!


Once done, let's end the process using close method.


As soon you end the terminate the process, File will get Unzipped. Let's display a message for user indicating the Successful termination of the process.

print('\nFile is Succesfully Unzipped!')

With these steps, we have successfully Unzipped the File using python. That's it!

Simple, isn't it? Hope this tutorial has helped. I would strongly recommend you to Check out the YouTube video of the same and don't forget to subscribe my Channel.

You can play around with the zipfile library and even explore more features. You can even make use of Python GUI using Tkinter.
