Python Tutorial: OS Module - Use Underlying Operating System Functionality

In this Python Tutorial, we will be going over the 'os' module. The os module allows us to access functionality of the underlying operating system. So we can perform tasks such as: navigate the file system, obtain file information, rename files, search directory trees, fetch environment variables, and many other operations. We will cover a lot of what the os module has to offer in this tutorial, so let's get started.

A tutorial for the sys module would help tremendously. It's difficult to find someone like you who can explain things in such detail as well as show how useful certain things within python can be without half-assing it. Thanks, Corey.

[@jordangillard2637]

Bless your soul Corey! The os module has always been such a pain to learn. When you first see it in code it's so cryptic. Thanks for breaking it down for us!

You are very good at explaining Python modules and their practical uses.

[@turboromy]

I was surprised how quick that search was wth os.walk().... and at the same time, wondered why Windows "Find" takes so long. Thanks for the great teachings.

[@knownwolf]

These Python videos are extremely helpful, thank you. I would be grateful if you added chapters. Some of the 10 minute plus videos have a lot of concepts and it would be great to jump back into a specific section when in need of a refresher. Keep up the excellent work and stay Pythonic my friend.

[@greenballscience9514]

Pythonic?

[@sameerspl]

Thanks Corey. I have started following you.. You make things so simple when it comes to using necessary commands in python.

[@user-qn5by5iv7u]

It is so demonstrating that you can hardly find any questions in the comments - there are only thanks and insparations 😏 The explanation is so clear that it leaves nothing to ask about 💎 Great job 👍

[@sreedharIITR]

For windows users, print (os.environ.get("HOME")) won't work as there is no HOME folder, instead it is USERPROFILE. So, type USERPROFILE instead of HOME.

[@murakumo222]

THANKS A LOT!!! i just can't get it work until i saw this comment. but why i can't get it to search other folders? am i only able to search within the same tree?

[@kostasnikoloutsos5172]

Thank you. Now I made this who gives you the desktop path.Pretty useful if you want to create something in the desktop.
os.path.join(os.environ.get("USERPROFILE"), "Desktop")

[@AnthonyMute]

@murakumo222 I don't know if you finally did it but assuming you are referring to os.walk() you could do the os.walk('C:\\Users') replacing the string with whatever directory you want the tree on.

[@cjz5757]

Sukant Arora os.environ.get('HOME') works just fine for me

[@MagnusAnand]

os.environ.get("HOME") worked fine for me in Windows 10

Moreover, I am a beginner to python language I thoroughly enjoyed ur videos, if u can suggest me best python book to ur sensibility and I guess it suits me and it helps me to learn further (I like physical like books). In case if u written any books related to this language can u suggest one (or) your favorite book, please......................................
