How to get parent venv executor relative to a jupyter kernel

kernel_venv.py

from pathlib import Path
import json

def get_kernels():
    venvs = !jupyter kernelspec list
    venvs_list = [i for venv in venvs[1:] for i in venv.split(' ') if len(i)>0]
    venvs_dict = {venvs_list[i]: venvs_list[i + 1] for i in range(0, len(venvs_list), 2)}
    return venvs_dict

def get_parent_env(kernel_name):
    kernels = get_kernels()
    kernel_json = Path(kernels[kernel_name]) / 'kernel.json'
    with open(kernel_json) as f:
        data = json.load(f)
    parent_env = data['argv'][0]
    return parent_env
