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

very simply, you could do

envs = subprocess.check_output('conda env list').splitlines()
active_env = list(filter(lambda s: '*' in str(s), envs))[0]
env_name = str(active_env).split()[0]

Answer 2

On Windows (might work but untested on Linux):

import sys
import os

# e.g. c:\Users\dogbert\Anaconda3\envs\myenvironment
print( sys.exec_prefix.split(os.sep)[-1] )

Answers using environment variables or assuming the path separator is "/" didn't work in my Windows/Anaconda3 environment.

This assumes you are in an environment.
