Python pathlib 如果目录不存在则创建目录

Question

如果我想指定一个路径来保存文件并创建该路径中不存在的目录，是否可以在一行代码中使用 pathlib 库来完成此操作？

Answer 1

是的，就是Path.mkdir :

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

来自 the docs :

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

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

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

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