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.
It is very excellent tutorial, much better than some paid python tutorial vedios in Udemy for i in range(1,1000000): print('Thank you so much for sharing this wonderful tutorial')

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.
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.

Thanks Corey. I have started following you.. You make things so simple when it comes to using necessary commands in python.
Excellent! I really appreciate you sharing so much knowledge at no cost. I am getting it slowly. Thank you
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.
Very nice! Tight and down to the core of what is needed!
Simple, well organized, great for beginners and informative. Nothing but least speaks English doesn't try to showoff.
You are an excellent presenter. The details were very well explained. I learned a lot. Thank you
Thank you! I've been using the os module for years and had no idea about os.walk()! Will be putting this to good use!
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 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.

Thank you Corey for your time and effort. Keep spreading the knowledge.
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 👍
Thank you Corey Schafer you're the best teacher for pyhton
Corey , thank YOU at the highest degree !
Great tutorial straight to point teaching the stuff that actually creates complex programs in a simple way is great
Super good whistlestop tour. Just what I needed.
Extremely useful and explained so well...thanks Corey!
for Windows users I used HOMEPATH instead of Home , use SET Command to be able to see all environment variables on CMD print(os.environ.get('HOMEPATH'))
you are much better than my faculty handling python course....
Another excellent tutorial! 💯 Thanks a lot Corey 🙏
You teach in a interesting way sir ,Thanks Today i have learned all things i was trying to learn from many days

First of all, your teaching style is good, and anyone grabs ur teachings easily, and thanks for teaching us. you are the best tutor I have ever come up with in python language. can u suggest any python language book, which is best to go through other than your channel? 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......................................
Thank you so much. It was super helpful
Thank you, Sir. Your videos are extremely helpful.
thank youuu! your tutorials are awesome!
Thank you. This was super cool.
Great vid! Very useful
For anyone who needs to work with paths and don't want to deal with the forward/backward slashes difference between Linux, Windows, and MacOS, you can consider or at least take a look at the module `Pathlib`. It is simpler and easier to manipulate in my opinion. My favourite part of the module is its slash operator, e.g. taken from the documentation ```python >>> p = PurePath('/etc') >>> p PurePosixPath('/etc') >>> p / 'init.d' / 'apache2' PurePosixPath('/etc/init.d/apache2') ``` Thus, you are free from the long `os.path.join()` method call introduced in 14:05 and make things cleaner and more readable.
now I understand this OS & good use case for file manipulation! THANK YOU COREY!
Thanks for the video, always the best!
Good tutorial... Thanks Corey....
very informative tutorial, thanks
gr8 tutorial..looking forward more videos..
Informative and chic tutorial :)
This was a very good video lesson for me as a beginner. I signed up for a Udemy class but found the content on OS Module functionality left me with some questions. I will definitely be using your videos as a resource1
