Python 3.12+osfunction

os.path.isdevdrive

os.path — existence and type checks

Check whether a path is on a Dev Drive (a Windows feature; False elsewhere; 3.12+).

Syntax

os.path.isdevdrive(path)

A Dev Drive is a Windows volume tuned for source code, builds and package caches. The function serves tools deciding where to keep caches or temporary files. It arrived in Python 3.12 for Windows only; since 3.13 it is available everywhere and always returns False on systems without Dev Drives. It may raise for a path with no recognisable drive.

Examples

# Python 3.13+ (на Windows — 3.12+)
import os
print(os.path.isdevdrive('.'))   # → False
print(os.path.isdevdrive('нет-такого-пути'))   # → False (существование пути не проверяется, исключения нет)
build_dir = os.path.join(os.getcwd(), 'build')
print('быстрый Dev Drive' if os.path.isdevdrive(build_dir) else 'обычный диск')   # → обычный диск (True бывает только на Windows-разделе Dev Drive)
print(os.path.isdevdrive('/'))   # → False (на Linux/macOS функция возвращает False для любого пути)
