Ten practical projects are: rename files, organize downloads, create backups, convert CSV files, remove duplicate rows, resize images, extract text, generate reports, check a website’s status, and send a personal reminder. Start with copies of your data and add a dry-run mode before making changes.
from pathlib import Path
source = Path("downloads")
for file in source.iterdir():
if file.is_file() and file.suffix.lower() == ".log":
target = source / "logs"
target.mkdir(exist_ok=True)
file.rename(target / file.name)Use pathlib for file paths, clear configuration variables, and structured logging. Make scripts idempotent: running them twice should not destroy or duplicate work. Validate file names and handle permission errors.
Automations that contact people, modify production data, or delete files need stronger safeguards: approval, backups, rate limits, and audit logs. Keep credentials in environment variables and test against a small sample first.
A useful automation is not the most complex one. It is a small, repeatable task with a clear before-and-after result.
