ospathsplitdrivepath

Ospathsplitdrivepath is a descriptive term used to refer to the process of splitting a filesystem path into a drive or root component and the remainder of the path. In the Python standard library, the closest official functionality is os.path.splitdrive, which performs this split.

The function os.path.splitdrive takes a single argument, path, and returns a two-element tuple (drive, tail). The drive element represents the leading drive or UNC root on platforms that support such constructs, while tail contains the rest of the path after that drive or root. The exact interpretation of drive depends on the operating system: on Windows, drive may be a drive letter like "C:" or a UNC root such as "\\server\share"; on POSIX systems, the drive component is always empty and tail is the full path.

Examples illustrate its behavior: splitdrive('C:\\Windows\\System32') yields ('C:', '\\Windows\\System32'); splitdrive('/usr/bin') yields ('', '/usr/bin'). For a UNC path like '\\\\server\\share\\folder', the result is ('\\\\server\\share', '\\folder'). Note that splitdrive performs lexical splitting and does not access the filesystem or verify path existence.

Usage notes: splitdrive is a lightweight utility in cross-platform code to separate a potential Windows-style drive from the rest of a path, enabling platform-aware processing. It is typically used alongside other path utilities such as os.path.normpath, os.path.join, or os.path.split.

Implementation details: the os.path module delegates to platform-specific implementations (ntpath on Windows, posixpath on POSIX). The Windows variant handles both drive letters and UNC paths, while POSIX variants return an empty drive. There is no standard function named ospathsplitdrivepath in the Python standard library; the canonical function is os.path.splitdrive.
