Create a new dir in python 3

You can create a new directory in Python 3 using the os module. Here's an example:

import os

# Create a new directory
os.mkdir("my_new_dir")

This will create a new directory called "my_new_dir" in the current working directory.

If you want to create a directory in a specific location, you can specify the full path:

os.mkdir("/path/to/my/new/dir")

Make sure to replace "/path/to/my/new/dir" with the actual path where you want to create the directory.

If the directory already exists, os.mkdir() will raise a FileExistsError. If you want to avoid this error, you can use the os.makedirs() function, which will create the directory and all its parents if they don't exist:

os.makedirs("my/new/dir")

This will create the directory "my/new/dir" and all its parents if they don't exist.

Note: On Windows, you may need to use os.makedirs() instead of os.mkdir() to create directories with spaces in their names.
