Why do we need to deactivate the Environment? .. considering, we want to create it for all of our projects and we need it.

[@BryanCafferky]

You create a separate environment for each project so you must deactivate one to switch to another.

After a days of struggle I found this video managed to explain clearly the concept of Virtual Environment. Great job!

[@ImCalledtheSentinel]

Thoroughly enjoyed this and created my virtual environment. Thanks Bryan

[@BryanCafferky]

Great! Thanks

[@BrianHoard]

Thank you for making this video. I just learned why these are important the hard way when I updated matplotlib and some library I was just experimenting with and completely broke my scripts. Now I have some steps to take to start using these.

[@BryanCafferky]

Yep. But when you learn the hard way, you remember. Thanks

great stuff Bryan! I have seen in the past using requirements file, how does that come into play with venv or does it come into play at all? thanks!

The same way you can install a single package using "pip install " you can install all you dependencies using "pip install -r ". And if you work properly (as tought by Bryan :P ), you run the pip install command while you are in your virtual environment.

I do discuss this in the video.
