Python pathlib make directories if they don’t exist

If I wanted to specify a path to save files to and make directories that don’t exist in that path, is it possible to do this using the pathlib library in one line of code?

Solution

  • Yes, that is Path.mkdir:

    pathlib.Path('/tmp/sub1/sub2').mkdir(parents=True, exist_ok=True)

    From the docs:

    If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX mkdir -p command).

    If parents is false (the default), a missing parent raises FileNotFoundError.

    If exist_ok is false (the default), FileExistsError is raised if the target directory already exists.

    If exist_ok is true, FileExistsError exceptions will be ignored (same behavior as the POSIX mkdir -p command), but only if the last path component is not an existing non-directory file.
