#Python #venv
In my older virtualenv video, I got a ton of requests to show how to use virtual environments on Windows. I hope this helps!
Hey Corey, thank you as always, i was trying to debug a Python for loop and was not sure if you talk about it anywhere. Also realized that sublime text 3 does not actually feature a python debugger, would appreciate your thoughts on this.
Thank you for all your videos. You should do one someday for pipenv!
And multiprocessing/multithreading
And sockets!
@@guipa I already have one for Pipenv. You can find that here: ruclips.net/video/zDYL22QNiWk/видео.html

The second hero after Corey Schafer :)
Thank you sir.
great job mate, thanks!
Is there any way to find out my existing virtual env?
Corey...You are the Guru of python world..thanks a lot for sharing your knowledge as always!
This has been so helpful! My class focused mostly on programming, and so we didn't really understand what we were doing during setup, but your videos make it very clear and easy! Thank you!
Thank you for this tutorial! I couldn't figure out how to use VENV on my own, even though I read a book called " Test Driven Development" because the author explained how to use VENV on mac. Corey, you're the man!
This is just perfect. I had been looking to understand venv for quite sometime now, and this clears it all. Great job!!!
This video saved me in setting up venv in windows, still relevant in 2021
Great tutorial! I am a hobbyist programmer, not an expert. I have been learning my self and this really helped.
This is the best venv tutorial that I've ever seen. Its bookmarked in my browser for over 1.5 years now. I get back to it whenever I miss something. Thanks man (y)
This is exactly what I needed just now for my project which is rapidly growing in complexity. Thanks Corey!
This is a simple and straight to the point tutorial. Well done man.
You've just gotten a subscriber.
Me too that was one of the best tutorials for real
This is the best video I've seen this year so far!!! I might be exaggerating but you sir have helped me solve a problem I was working on for the last 20+ hrs!
This was great. I was thinking of questions as the video moved along and then you ended up answering them all. Great work Corey.
He does that doesn't he. One of the most clear videos on venv.
Thanks @Corey Schafer. trying to follow some Django tutorial on RUclips but just couldn't activate the virtual env, windows would accept the CMD but won't activate the venv :
Setup: win 10, gitbash, python 3.7
Create the venv: python -m venv my_dir
Activate the venv: source my_dir/Scripts/activate
Stackoverflow to the rescue. Love your work btw thanks from the rest of us.
Yet another video from maestro Schafer that makes difficult subject looks pretty easy.
Respect!
I really needed this video.
Thanks Corey!!
jesus you don't know how much this helped me. All tutorials I've watched were done on Mac haha
Many thanks for this tutorial. You have saved me from what I spent a whole weekend trying to figure out.
Thank you so much! I’ve searched and read and tried everything on the net on how to set up venv but this is the only one that worked.
i was totally confuse and frustrated just before completing the 17 minutes of this video
honestly i feel really relief now..
you got a new fan now man.....
thank you...
Thank you Corey, I almost gave up trying to work with venv, until i saw this brilliant post...
This guy is a real instructor. Great work a lot of effort there thank you
This is a very good video to learn venv module in short time. I appreciate your work.
Corey, I watched lot of videos about the environment and virtual environment but could not understand. Your explanations technique is the best. Thanks.
in short
(i am assuming you have activated virtual environment)
type: pip freeze
(you will see all requirements)
copy all to requirements.txt (16:40 observe copying process carefully)
//(make sure requirements.txt is in project folder)
type: deactivate
(venv will be deactivated)
type: pip install -r .
equirements.txt
(all requirements will be installed)
type:.\venv\Scripts\Activate.ps1
(activating environment)
Thanks Corey for creating this, I think every RUclips turorial uses Mac, and I could not find a decent source for learning Virtual Environments...
Thank you Corey for this excellent video on virtual environments. I needed it. You do not assume anything as known and this is very good, especially for beginners. For me, the best explanation on this topic I found!
Thank you so much for resolving the issue. other videos on RUclips wasted my time.
Good video, cleared a lot up. The programming is easier than the setup.
This is very well explained and easy to follow. Thanks for the tutorial!
Super helpful. Clear, concise, to the point. Thx much, m8.
You are the best I have been like 2hour trying to figure it out , and with you it took like 1min
Even after 4 years, it is still a valid a video 😍
Thank you Corey, you actually explained away all the questions
a noob like me came with. Things I just didn't understand and most videos
skip, I guess cuz its obvious to the creator. Very helpful tutorial 🙏 thank u
This guy is the GOAT, simple and easy tutorials! This helps alot!
Thx Corey! This video is still helping me out in 2022
This video really helps me a lot. Hope you'll make more videos like that.
Very good one! Thank buddy. I like your videos. Your attitude and way of passing the stuff to your viewers is just excellent.
Thank you so much, love how simple and clear this tutorial is! :)
Great videos Corey. You are the go to when I am looking to understand something python. Thanks for helping the community!
Pretty much what the rest of the comments say - great video and thanks once again!
The single most important Python tutorial since Python's existence. Virtual environments are the most effective anti-hair loss treatment ever invented :)
You are talking very fast, but you covered everything important to know. Many Thanks for that
You're right, is is simple and doesn't have the bells and whistles of pipenv. The one thing I really prefer in pipenv is your pipfile is update automatically. Here, you would have to remember to add something to your requirements.txt after you install it.
Never found a more fitting video to my problem, thanks a lot!!
you are awesome i don't have words to describe how helpful this video was thanks alooot man
This was so helpful and concise. Thank you very much from a Python (heck, programming in general) noob!
Thank you, that was really informative! Clears up questions.
Thank you so much. In 2021 this video is really good, but i had changed the second command to "python3 -m venv project_env". Just add the 3 in python.
This video was great for me, I'm just learing python for the first time and as a windows user it was easy to follow the steps, congratulations. It would be great if you are able to add the english subtitles in the video because as me that I'm not an english person many other people could watch the video easer reading the subtitles
Nice video. Conda has been acting weird with pip packages so I've ditched anaconda and gone this way. Minor note, you can leave off the .bat when activating
This is helpful Corey, comprehensive and good phase!
@ 3:34 my issue was solved thanks for the content!
Thank you for this, you are the foundation of whatever i do or develop related to python
Thank you Corey. All this virtual environment stuff was really confusing regarding how many of them there are. I'm going to stick with the baked in one, venv.
My man...I've been struggling with this. Great video. Thank you so much.
This video is a simplified as a sip on a cup of coffee thank you so much Corey
Your videos are the best. Thanks for sharing your knowledge.
Just to add something to this great tutorial. we can dump the result of "pip freeze" into "requirements.txt" file by doing
pip freeze > requirements.txt
removing the need to copy the pip freeze results manually.
I think he was saying this caused his command prompt to change colour hence why he didn't do it
This is the best video on the subject of python virtual environment! Thank You .
Thank you for sharing! saves a ton of time, trying to search for solutions on your own
Most simplest explanation there can ever be! 100000%
Thank you very much for this video :) It is very helpful and I learnt a lot!
Sir, you're just best.
If anyone wants to automate the creation of requirements.txt file then just type in this:
*pip3 freeze > requirements.txt*
It will automatically save that.
You are the best instructor!
Loved the solution finally my problem is solved.. bless you man.
Very helpful and you make it very intuitive, thank you!
Thanks Corey Schafer, it was a very helpful tutorial!
I want to confirm that I understand it correctly.
So the venv module here, is used to create... a virtual environment.
it's like a copy of python, but one that I can mess around with and don't have to worry about.
once I'm done with it or don't need it anymore, I can simply delete it like deleting a normal folder.
whatever I do in the virual environment, doesn't affect the main python installation (/AppData/Local/.../Python).
thank you sir your video clear my lost of doubts
Super..
Excellent explanation
you are unique, keep it up !!!!!!!!!!!!!!!!!!!!!!!!!!
Amazing tutorial - No one explains it like you do Corey!
Great. Finally even me understood this stuff.
I'd have a question. When I use venv and when I should use docker?
A tutorial of this kind for docker would be awesome. Thanks a lot.
very well explained...thanks...
Thank you! That was the best explanation I encountered on RUclips!
Awesome Man . You are awesome Corey . Thanks a ton . I love the way you make things simpler .
Thank you very much it was very useful
Man, you are just amazing. Very clear explanations. Saved me a lot of trouble.
Incredibly useful! Big thanks for detailed description and instructions
Thanks for posting this, now I finally get how to use it in Windows :-)
Had trouble activating venv so I had to cd into Scripts, dir to see the contents and activate.bat, but it worked! thnx
Thank you so much Corey for making these wonderful videos. They are all easy to understand and follow. I learn so much from them. I will join patreon to contribute to the group. Thank you for all you do!
Thanks! That’s a huge help!
Great job. I found this very helpful.
If I could like the video 10x I would, thanks bro
Very helpful. Thank you!
Thanks sir you're a blessing you're way of explanation is easy and interesting.
Awesome and Easily understandable explaination.
Best venv tutorial hands down. Thank you. Subscribed :)
superb video that provided me with everything I needed - no more, no less. thanks so much!
To create the enviroment on python 3.8 the command is: py -m venv
Espectacular la explicacion.... Buenisimo... Gracias.
Thanks, this was really helpful for me!
Thank you so much, exactly what I needed!
Thanks a lot you're an amazing tutor
Amazing and comprehensive video, Many thanks Corey.
It is possible to just add the requirements.txt by using the pip freeze > requirements.txt command without creating the file ourselves
Great video
Thanks a lot for sharing this informative information beautifully
Thanks, very good tutorial Corey!
