It's worth mentioning that pathlib restricts the first character of a Windows drive name to the set of ASCII letters in pathlib._WindowsFlavour.drive_letters. For example:

    >>> Path('3') / 'C:3'
    WindowsPath('C:3')

vs.

    >>> Path('3') / '{:3'
    WindowsPath('3/{:3')

This design supports normal DOS drive names such as drives assigned automatically or via diskmgmt.msc, diskpart.exe, and so on.
