How to Use venv to Create Virtual Environments in Python 3 (multiple versions)

[@c0kain361]

Literally the best tutorial I have found. Started reading black hat python 2nd ed and this expanded on the first chapter so much more. Thank you!!!

[@TonyTeachesTech]

Thanks so much!!

[@EdwardAmarh-01]

Hey God bless you. This really was straight forward and understandable. I loved every bit of this tutorial

[@TonyTeachesTech]

Thanks Eward, happy to hear that!

[@hemanthsaji3606]

Amazing tutorial Tony. Straightforward and clear. I have a question. If we install a Python library only in a particular Virtual environment and if we make a script using modules in that library and make that script executable can I run it without Virtual environment in my regular home directory. Do I need to always run that particular script in virtual environment ?

[@aasthavarma2977]

This really was crystal clear. Loved it !!

[@TonyTeachesTech]

Thanks!

[@ffhhffh]

Straight and to the point. Thank you!

very easy very short and simple explain thank !

[@TonyTeachesTech]

You are welcome!

[@hassanrisvy3947]

Guys don't forget to Install virtual environment packages first. For python 3.7 (or any 3.x): sudo apt-get install python3.7-dev python3.7-venv

[@Remiisola]

MEGA thanks for sharing this. You saved my day :}

[@eclipsedegazpach7066]

Ok, but you already had different versions of python living in your system, a missing piece of info is how do you manage to download and hold those diff versions without getting into conflict with your global ver of python

[@jarodmorris4408]

I am not going to install a different version of python on my VPS because it could break my entire VPS. How do you install a version of python in JUST your venv?

[@AbdulKareemAbdulRahman]

how would one upgrade the phyton in a virt environment? thanks? for instance my system wide python says it is 3.11.3 but my venv says it is 3.7. wld be grateful for any help or signposting

[@apocalypseb7x]

Very useful, thanks for sharing!

[@enricofr7079]

thank you, this is very helpful... i always use anaconda to make venv and dont know how to make it manually coz im moving to manjaro

[@TonyTeachesTech]

You're welcome!

[@slayer_dan]

cleared my thoughts, thank you

[@TonyTeachesTech]

Good!

[@ldELuxEl]

Pls help... I accidentally changed python version for my environment. What is the best way to revert to previous python version?

[@CanDoSo_org]

Thanks, Tony. One question. What should I do if there is a new version of python released. Update once or I have to update for each of these virtual environment?

[@TonyTeachesTech]

Thanks for watching! You need to update for each of the virtual environments if you think its necessary.

[@CanDoSo_org]

Thanks, Tony.@@TonyTeachesTech

Preview on Tab press in terminal! Awesome feature I didn't know)

[@MrRobeezy29]

it doesn't work when I run which python in windows powershell....please for the love of god can someone just explain wtf I need to do......

[@TonyTeachesTech]

I think on Windows it's where instead of which

[@LanceThorpe]

awesome!

[@TonyTeachesTech]

Thanks!

[@RagHelen]

So, it does not clear up the mess of multiple installations, but just creates another mess on top of it.

[@TonyTeachesTech]

An organized mess in my opinion

[@souvikayan]

how will i setup venv in python 3 older versions?

[@TonyTeachesTech]

Not sure about that

[@artemis2751]

Thanks for the video! How can you make a virtual env. using for example python3.6? (or any other version which is not in your mac).

[@TonyTeachesTech]

You will have to build python from source. You can watch this video if you're not sure how to do that kzbin.info/www/bejne/aaXSeXWVmdRqpa8

[@redspotaquashrimps]

what is the difference between this virtual environ and Anaconda?

[@TonyTeachesTech]

I see Anaconda as probably a wrapper of some sort around this or at least very similar functionality

[@bernabesolideogloria]

hi Tony how are you?? here from Chile, sorry, but the instructions for python 3.7 did not work for me or am I missing something to improve? Could you help me please? here are the steps i run: 1.which python 2./usr/bin/python3 -m venv ~/env/py37 3.~/env/py37/bin/activate 4.which python 5.python --version and the system response: Python 3.8.9

[@TonyTeachesTech]

What went wrong?

[@souvikayan]

what is the application name in which u are setting up the venv

[@TonyTeachesTech]

Terminal. It's built into Mac and Linux

[@2bitninja280]

Thanks for the video. I have a few questions. When you left the 1st virtual environmental you typed deactivate. So that means you shutdown the virtual environment . Is there a way to leave the VE without deactivating it? If so can you switch between more then one that is running. I guess you could just have more then one terminal running. The only issue with that is if you are remotely connecting the sever, you could be kick off by the server terminating the connect due to inactivity.

[@TonyTeachesTech]

You are "deactivating" the virtual environment in your terminal session, but it still exists on the filesystem it will still work properly if you access it externally

[@arifyalcn3546]

Good Video I'm a little Understand :-D But I'm using Arch and I have 2 question. how to downgrade virtualenv python version? ı'm download python old version and ı'm not see folder in bin Help Mee

[@TonyTeachesTech]

I would suggest to create a separate virtual environment rather than trying to downgrade

[@arifyalcn3546]

@@TonyTeachesTech I'm understand you but I'm main question is "downgrade virtualenv in python version". Example my system have 3.9.10 but I'm want to create 3.6.0 how to make this. Note: Very Very Thank you

@@TonyTeachesTech Hi Tony, Is it possible to create one virtual env with multiple python versions (py2 and py3) ?

[@TonyTeachesTech]

@@SandeepKumar-sw5lo Yes, you can have multiple virtual environments where each one can have a different version of python
