How do I find the name of the conda environment in which my code is running?

Question

I\'m looking for a good way to figure out the name of the conda environment I\'m in from within running code or an interactive python instance.

The use-case is that

Answer 1

I am using this:

import sys
sys.executable.split('/')[-3]

it has the advantage that it doesn't assume the env is in the path (and is nested under envs). Also, it does not require the environment to be activated via source activate.

Edit: If you want to make sure it works on Windows, too:

import sys
from pathlib import Path
Path(sys.executable).as_posix().split('/')[-3]

To clarify: sys.executable gives you the path of the current python interpreter (regardless of activate/deactivate) -- for instance '/Users/danielsc/miniconda3/envs/nlp/bin/python'. The rest of the code just takes the 3rd from last path segment, which is the name of the folder the environment is in, which is usually also the name of the python environment.
