how can I find out which python virtual environment I am using?
You can use sys.prefix
to determine which virtualenv you're in.
import sysprint(sys.prefix)
from the sys
docs
A string giving the site-specific directory prefix where the platform independent Python files are installed
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.)
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.
