# 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.

```python
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.

```python
import os

os.makedirs('/root/directory/nested_directory')
```

The result will be the same as the previous one.
