How can I safely create a nested directory in Python?
The most common way to safely create a nested directory in Python is using the pathlib or os modules.
Using pathlib
You can create a nested directory in python 3.5 or later using the Path and mkdir method.
from pathlib import Path
p = Path('/root/directory/nested_directory')
p.mkdir(parents = True, exist_ok = True)
An important part of the code above is the parents argument is set to True. The default value is False, meaning that if the parent directory (in this case /root/directory) is not found, an error is thrown. If we set parents to True, the error won’t be thrown and the non-existing parent directory will be created along with the nested directory.
The exist_ok arguments ensure that an error won’t be thrown when the directory already exists.
Using os.makedirs
Another possible method is to use os.makedirs function.
import os
os.makedirs('/root/directory/nested_directory')
The result will be the same as the previous one.
