I have several virtual environment in my computer and sometimes I am in doubt about which python virtual environment I am using. Is there an easy way to find out which virtual environment I am connected to?

You can use sys.prefix to determine which virtualenv you're in.

import sys
print(sys.prefix)

from the sys docs

A string giving the site-specific directory prefix where the platform independent Python files are installed

    If you need a code one-liner for the command line: `python -c "import sys; print(sys.prefix)"` – jshd Nov 23 '22 at 14:15

Usually it's set to display in your prompt. You can also try typing in which python or which pip in your terminal to see if it points to you venv location, and which one. (Use where instead of which on Windows.)

  • On Windows this gave me a list of all available Python environments. The one at the top of the list is the current one. Might seem obvious, but wasn't to me initially. – jshd Nov 23 '22 at 14:16

From a shell prompt, you can just do echo $VIRTUAL_ENV (or in Windows cmd.exe, echo %VIRTUAL_ENV%).

From within Python, sys.prefix provides the root of your Python installation (the virtual environment if active), and sys.executable tells you which Python executable is running your script.

Try

echo $Env:VIRTUAL_ENV

if you are in Windows Powershell (which is for example the default terminal in VSCode).
