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!!!

very easy very short and simple explain thank !

[hemanthsaji]

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 ?

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

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

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

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?

[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?

[ldELuxEl]

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

[prakhars]

2:18 how did you get that easy_install? I don't have this.

thank you... Not All Heros Wear or save lives some save us from our stupid version of our self

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.

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).

[redspotaquashrimps]
