pathlib for filesystem work

pathlib is the standard-library tool for filesystem paths. It usually leads to clearer, safer code than building path strings by hand.

What is pathlib?

from pathlib import Path

config_path = Path("config") / "settings.json"
print(config_path)

Output:

config/settings.json

Path objects support joining, inspection, and common filesystem operations in a readable way.

Why it is useful

It helps with:

• cross-platform path handling
• path joins without manual slashes
• readable access to names, suffixes, and parents

Rules of thumb

• Prefer Path objects over manual path strings.
• Use / to join path segments.
• Keep values as paths until a library truly needs a string.
