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.

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 5 лет назад

Pythonic?

@sreedharIITR 7 лет назад

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 7 лет назад

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 7 лет назад

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 7 лет назад

@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.

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......................................
