How to create a subdirectory with Python?

In this article we will learn how to create a subdirectory with Python, in a simple way using the language’s libs.

What’s up programmer, ok? Let’s learn more about Python!

For Python version 3.5+ we have a very easy way to solve this problem

Basically let’s call Path from lib pathlib

And use the mkdir method

See the example:

from pathlib import Path

# creating the directory
Path("dir").mkdir(parents=True, exist_ok=True)
# creating the subdirectory
Path("dir/subdir").mkdir(parents=True, exist_ok=True)

That way you will create the directory first, then the subdirectory

But if you already have the main directory, you can use only the second sentence and then the subdirectory will also be created

Note that when using only the second method, you need the parent directory to exist

Otherwise Python will generate an error in your program

This also ensures that we don’t create a parent directory by mistake, which can be very bad for the program.

And the good thing is that we do all this operation in one line

Python showing again its power and simplicity! 😀

We use the Path that comes from the pathlib library

In it we have the mkdir method, which can create both directories and subdirectories
