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.

+ os.getcwd() => get current working directory
+ os.chdir(<path>) => change directory
+ os.listdir() => list directory
+ os.mkdir(<dirname>) => create a directory
+ os.makedirs(<dirname>) => make directories recursively
+ os.rmdir(<dirname>) => remove directory
+ os.removedirs(<dirname>) => remove directory recursively
+ os.rename(<from>, <to>) => rename file
+ os.stat(<filename>) => print all info of a file
+ os.walk(<path>) => traverse directory recursively
+ os.environ => get environment variables
+ os.path.join(<path>, <file>) => join path without worrying about /
+ os.path.basename(<filename>) => get basename
+ os.path.dirname(<filename>) => get dirname
+ => check if the path exists or not
+ => split path and file extension
+ dir(os) => check what methods exists

its so sad that this guy has not uploaded any content for over a year now... his tutorials are always the best, most methodically thought out pieces of work on the platform

[chuanliangjiang]

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

[codaadoc]

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.

[jordangillard]

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!

[khaled-dz]

The best one i have ever seen in teaching coding . Thank you so much man

[bactran]

every time I need a tutorial video for Python, Corey is always the best one with really well organized, fully information and easily to remember. Thanks a lot Corey

[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.

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

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.

[yomajo]

I never read your descriptions, but after seeing what's on your amazons' wish list, I can tell, you aint no ordinary tutor. Respect. Sharp, evolving mind.

[sahajjaiswal]

you are much better than my faculty handling python course....

[veeresharadhya]

please make one tutorial for sys module as well... :-)

[sujithnair]

for Windows users I used HOMEPATH instead of Home, use SET Command to be able to see all environment variables on CMD

[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.

[qnbyivu]

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 👍

[zacharysimpson]

I've been learning python for several months now, and not once did i ever see anything about print(dir(<module>))! Like given!

[GihanJayaneththie]

Simple, well organized, great for beginners and informative. Nothing but least speaks English doesn't try to showoff.

[JoyDavidson]

Corey, I hope you are well today. 🤙🤙 I have been sober for one year. We got this.

[erfantaghvaei]

I love Corey's teaching ... and accent!
