Python's os module

The os module has many uses. We won’t be covering everything that it can do. Instead, we will get an overview of its uses and we’ll also take a look at one of its sub-modules, known as os.path. Specifically, we will be covering the following:

• os.environ
• os.chdir()
• os.getcwd()
• os.getenv()
