Pathlib

Introduction

Pathlib provides object-oriented filesystem paths, cleaner than os.path.

Basic Path Operations

from pathlib import Path

p = Path(".")

# Traversing
p / "subdir" / "file.txt"

# Reading and writing
p.write_text("Hello")
content = p.read_text()

# Glob patterns
list(p.glob("*.py"))
list(p.glob("**/*.txt"))

Path Properties

from pathlib import Path

p = Path("example.txt")

p.name       # 'example.txt'
p.stem       # 'example'
p.suffix     # '.txt'
p.parent     # Parent directory
p.parts      # Path components

p.exists()
p.is_file()
p.is_dir()

Creating Paths

from pathlib import Path

# Absolute paths
Path("/home/user/file")
Path.cwd()       # Current working directory
Path.home()      # Home directory

# Home-relative
Path("~/documents").expanduser()

Practice Problems

1. Navigate directory tree with pathlib
2. Find all Python files recursively
3. Create file backup with new extension
4. Walk directory hierarchy
5. Resolve file paths safely
