Python Script to Compress a Directory into a ZIP Archive

This short tutorial demonstrates how to create a zip archive of a specified folder using Python's built‑in zipfile module.

The zip_dir function first builds a list of all files in the target directory (handling both single files and nested directories), then iterates over the list, printing each relative path and adding it to a new zip file opened in write mode with compression.

import os, os.path import zipfile def zip_dir(dirname, zipfilename): filelist = [] if os.path.isfile(dirname): filelist.append(dirname) else: for root, dirs, files in os.walk(dirname): for name in files: filelist.append(os.path.join(root, name)) zf = zipfile.ZipFile(zipfilename, "w", zipfile.zlib.DEFLATED) for tar in filelist: arcname = tar[len(dirname):] print(arcname) zf.write(tar, arcname) zf.close() zip_dir('/xxxxxx/docs', '20180504.zip')
