In this video, we cover the OS module with Python 3. The main purpose of the OS module is to interact with your operating system. The primary use I find for it is to create folders, remove folders, move folders, and sometimes change the working directory. You can also access the names of files within a file path by doing listdir(). We do not cover that in this video, but that's an option.
The os module is a part of the standard library, or stdlib, within Python 3. This means that it comes with your Python installation, but you still must import it.
Sample code using os:
All of the following code assumes you have os imported. Because it is not a built-in function, you must always import it. It is a part of the standard library, however, so you will not need to download or install it separately from your Python installation.
curDir = os.getcwd() print(curDir)
The above code will get your current working directory, hence "cwd."
To make a new directory:
To change the name of, or rename, a directory:
To remove a directory:
With the os module, there are of course many more things we can do. In many scenarios, however, the os module is actually becoming outdated, as there is a superior module to get the job done. We will get to those soon enough. It is still a good idea to at least know some of the basics of the os module. I especially like to use it to create directories. If you ever create a setup.py file, the creation of directories and the placing of files within them will be essential.
