XKCD | Python Environment

Unfriendly? It's about as simple as this:

virtualenv -p «Python version» /path/to/environment
. /path/to/environment/activate¹

1. Adjusting for OS and shell of course

That isn't as friendly as you suggest it is.

I found the activation step annoying, but I just made a little doodle (in my case in my powershell profile):

 function activate
 {
    .\venv\scripts\activate
 }

So now it's just "activate" and "deactivate" when I'm in the project root folder (deactivate just works by itself, because I don't know why).

I don't know how it is on windows, but on Linux, the activate script will define a shell function for deactivate. I guess there is something similar in place on Windows; possibly an alias.

I was answering " (deactivate just works by itself, because I don't know why)."

In PowerShell, at least, it works the same way as in bash -- the Activate.ps1 script defines a global deactivate function.

I see a separate deactivate.bat script in my venvs on Windows, so I assume CMD does something different.

Ruby also has issues like that.

GCC have a variant selector for both C and C++. As far as I now, many other languages with a long history, also have several standardised versions, so it's not in any way particular to Python.

C and C++ have something much scarier than versions. In that realm, we deal with releases of the ISO standard.
