How Can I Create a Directory and its Missing Parent Directories in Python?

Creating a Directory and Missing Parent Directories

Creating a directory along with any missing parent directories can be done in Python using the pathlib.Path.mkdir function. For Python versions before 3.5, there are several options to achieve this result.

One approach is to use os.path.exists to check if the directory exists, followed by os.makedirs to create it. However, a race condition exists between these two calls, where another process could create the directory before os.makedirs is executed.

Alternatively, a blanket error catch on os.makedirs can be employed, but this may ignore failures due to other factors like insufficient permissions or a full disk.

Another solution is to use the FileExistsError exception exposed in Python versions 3.3 or use the exist_ok keyword in os.makedirs, which was introduced in Python 3.2 .
