When you run this script, you should now see that the single_file.zip is much smaller than the actual bitmap file. Zf = zipfile.ZipFile('single_file.zip', mode='w', compression=zipfile.ZIP_DEFLATED)

Python download and unzip file archive#

# Instantiate a new zipfile object creating the single_zip.zip archive and compressing it To compress the files inside the archive, you must specify the ZIP_DEFLATED attribute, as shown below. By default, that attribute is set to ZIP_STORED, meaning no compression. The zipfile module uses various compression attributes such as ZIP_STORED, ZIP_DEFLATED, ZIP_BZIP2, and ZIP_LZMA that dictate how Python compresses the files inside. Finally, add a compression parameter when instantiating the zipfile object. With ZipFile('single_file.zip', 'w') as zipfile: zipfile.write('all_black.bmp')Ħ. Since zipfile is a context manager, you can also use the with statement e.g. To compress the files inside, you must perform one more step.

By default, the zip file is not compressed. Congrats! You’ve zipped up your first file! But wait. Once you run the script, you should now see a file called single_file.zip in the folder. You can specify absolute paths instead when specifying file names. The relative path looks for the files in the current directory, where Python is currently running. # Close the archive releasing it from memory Zf = zipfile.ZipFile('single_file.zip', mode='w') # Instantiate a new zipfile object creating the single_zip.zip archive. The zipfile module is a built-in Python module that contains all of the functions you’ll need to zip and unzip files with Python. This tutorial will be saving the demo script in the home directory or ~/demo.py.Ĥ. Create a new Python script called demo.py. Not all types of files will compress as well.ģ. The tutorial files are bitmap files, which greatly benefit from compression. You’ll also have a demo.py Python script that contains all of the code in this tutorial. Once you do, you should four bitmap files all_black.bmp, all_blue.bmp, all_green.bmp, and all_red.bmp. If you’d like to follow along exactly with the tutorial, create a directory at ~/pythonzipdemo and download these BMP files into it. This tutorial will begin with the simplest possible method and will build upon various techniques.Ģ. Let’s get started and first focus on zipping files with Python.
