In an attempt to answer this objectively, I think the shortest argument for using both boils down to:

The Gitpod provides your development environment: editors, IDEs, Python installations that a virtual environment can use, etc.

The virtual environment provides your application's execution environment: the exact Python version and packages it needs to run.


Your preferred tooling and workflow, however, might make this distinction moot.
As far as I understand, Gitpod creates a pod which runs a Linux server container that includes my pre-configured IDE.
I am not too familiar with pods and containers, so please correct me if I'm wrong.
To my understanding, a container is essentially a VM, or are there any differences between the two?
Now, moving on to Python, which I am also just getting to know.
So a common practice is to set up a virtual environment, so that packages will be installed in there, and not globally, on the computer running the project.

Note - I will be abbreviating with "venv", but I will not be specifically referring to venv/virtualenv/etc.

Comparing it to NodeJS with which I am more familiar, that would be the same as using project/.node_modules vs usr/local/lib/.node_modules
By default npm i installs on the repository, and only installs on the machine when using the -g option.
Is that correct so far?*

So, with that information in mind, since Gitpod is running a container specifically built to serve as a single project IDE - Do I even need to run a venv?

I can see a use case in which I may be testing how my code runs against Python3 and Python2.8, thus using two different venvs
(I now wonder how that would look code-wise, how would the scripts import the correct libraries, but that question is way off-topic 😅)

Anyway, my question assumes:

If I were to use it on a local machine, I'd only need one venv
In terms of Python version and package collisions:

Either the default Gitpod image satisfies my needs
Or, well, I can edit the image myself anyway




* Footnote - I apologise for asking many questions beside the main one.
I hope it is not against the rules, I simply want to know if I understand correctly
Since Gitpod is running a VM, is a Python venv unneeded?
