There are many **alternatives** to managing virtual environments, package dependencies (requirements), projects.

Once you are ready and want to use a tool to **manage the entire project**, packages dependencies, virtual environments, etc. I would suggest you try [uv](https://github.com/astral-sh/uv).

`uv` can do a lot of things, it can:

* **Install Python** for you, including different versions

            Configuration for different proxy profiles. Multiple proxy profiles
            might come in handy for anyone working from a notebook or other
            mobile platform, to enable easy switching of entire proxy
            configurations by simply specifying the profile id, again either from
            the command line or from the defaults section below.
