Filesystem Automation with pathlib

Standard Library

pathlib Cheat Sheet

`pathlib.Path` gives you cross-platform path handling, globbing, and file reads/writes in one interface.

Create & join pathsPerform filesystem ops

Paths

from pathlib import Path

root = Path(__file__).parent
reports = root / 'reports' / '2024'
reports.mkdir(parents=True, exist_ok=True)

• Use / operator to join segments.
• Path.home() returns the user directory.

Operations

Task	Snippet
Read text	Path('notes.txt').read_text()
Write text	Path('notes.txt').write_text('Hello')
Iterate files	for p in root.glob('*.log'):
Check existence	path.exists()
File metadata	path.stat().st_size
