In Python, one of the main and most important libraries is os. It provides an interface for interacting with the operating system, which is especially important in DevOps for managing files, processes, environment variables, and other system resources.

Example of using os:

import os

# Get the current working directory
cwd = os.getcwd()
print(f"Current directory: {cwd}")

# Create a new directory
os.mkdir('new_folder')

# List files in the directory
files = os.listdir('.')
print(files)

Besides os, libraries subprocess for running external commands and sys for working with interpreter parameters are often used.
