Python Tutorial: OS Module - Use Underlying Operating System Functionality
HTML-код
- Опубликовано: 5 апр 2016
- 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.

thank you best friend
Thank you best friend forever.
thanks bro
Thank you best friend
thank you bro
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
You already finished all 143 of the python videos?
Nobody cares that some 15 year old girl working for the Mexican cartels goes around raping dude to try and extort them.
Nobody gives a shit.
I agree .. he is sorely missed
yeah right 😞
He’s back in action now!
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')
while True:
print('Thank you so much for sharing this wonderful tutorial')

Print(“Thank You So Much”)
@@Pr0G4m3R4u 😂😂😂
@@greenballscience9514 it should be like:
import os
os.system(''C://Python//Python.exe, C://pyproj//thankyou.py")
Error, wait for script to finish..
.. CTRL+C
>>> python Greenball_Science.py
now you were saying?
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.
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!
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.
Pythonic?
You are very good at explaining Python modules and their practical uses.
Thanks Corey. I have started following you.. You make things so simple when it comes to using necessary commands in python.
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
Your grammar is wrong, the quote should be, "Every time I need a tutorial video for Python, Corey is always the best one with really well organized, full information and easy to remember. Thanks a lot Corey."
@@codingisthebest3914 Ich würde mal sagen,dass du ein Klugscheißer bist :)
@@codingisthebest3914 Based on his name, he's not American, so it's fine. I agree with what oneLittleDuck wrote in German. LOL
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.
Excellent! I really appreciate you sharing so much knowledge at no cost. I am getting it slowly. Thank you
Thank you Corey for your time and effort. Keep spreading the knowledge.
You are an excellent presenter. The details were very well explained. I learned a lot. Thank you
Super good whistlestop tour. Just what I needed.
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!
The best one i have ever seen in teaching coding . Thank you so much man
Corey , thank YOU at the highest degree !
please make one tutorial for sys module as well... :-)
yeah thumbs up!
Yeah Corey! one for the sys module please! :)
and subprocess ;-)
and pdb debugger as well if possible :)
Veeresh Aradhya yes please. Been struggling with stdin and stdout
you are much better than my faculty handling python course....
Simple, well organized, great for beginners and informative. Nothing but least speaks English doesn't try to showoff.
Thank you Corey Schafer you're the best teacher for pyhton
Extremely useful and explained so well...thanks Corey!
Very nice! Tight and down to the core of what is needed!
Great tutorial straight to point teaching the stuff that actually creates complex programs in a simple way is great
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.
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?
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")
@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.
Sukant Arora os.environ.get('HOME') works just fine for me
os.environ.get("HOME") worked fine for me in Windows 10
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'))
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 👍
Another excellent tutorial! 💯
Thanks a lot Corey 🙏
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.

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
Which Udemy python class are you taking? I plan on taking a Udemy class for Python to supplement what I learn from Corey's channel. Thanks.
Hi Corey Schafer,
It was awesome pin to pin teaching. Thank you so much!!
Really helpful
Top, excelent tutorial!
