Python zipfile Module: How to Install and Explore Advanced Features

The Python zipfile module is a built-in library in Python, which provides the functionality to create, read, write, append, and extract ZIP files. It allows developers to manage collections of files into a single archive, making it easier to transfer and store multiple files efficiently. The zipfile module is compatible with Python version 3.x.

Applications

The zipfile module is widely used in various scenarios, including:

• File compression: Reducing the file size for easier storage and transfer.
• Archiving: Combining multiple files into a single archive for organization or distribution.
• Data packaging: Preparing datasets or resources for deployment in applications or for sharing with others.
• Reading existing archives: Extracting and manipulating files from already created ZIP files available in systems or repositories.

Installation Instructions

The zipfile module comes as a default module in Python, so there is no need for separate installation. It can be directly imported and used in any Python 3.x environment.

import zipfile  # Importing the zipfile module to work with zip files

# Specify the name of the zip file to be created
zip_file_name = 'example.zip'

# Creating a new zip file in write mode
with zipfile.ZipFile(zip_file_name, 'w') as zip_file:
    # Adding a single file to the zip file
    zip_file.write('file1.txt')  # Adding file1.txt to the zip archive
    zip_file.write('file2.jpg')   # Adding file2.jpg to the zip archive

# The archive 'example.zip' now contains file1.txt and file2.jpg

import zipfile  # Importing the zipfile module

# Name of the zip file from which we want to extract content
zip_file_name = 'example.zip'

# Opening the existing zip file in read mode
with zipfile.ZipFile(zip_file_name, 'r') as zip_file:
    # Extracting all files in the zip archive to the current working directory
    zip_file.extractall()

# All files from 'example.zip' have now been extracted to the current directory

    # Listing all files contained in the zip archive
    file_list = zip_file.namelist()
    print("Files in the zip archive:")
    for file in file_list:
        print(file)  # Printing the name of each file in the archive

# This will print out the list of filenames contained in 'example.zip'
