Running this script on Windows?

[Winfried]

Hello,

I need to run a Python script that contains the following lines :

#! /usr/bin/env nix-shell
#! nix-shell -i python3 -p "python3.withPackages(ps: with ps; [pandas scipy requests (python3Packages.callPackage ./openrouteservice-py.nix {})])"

import sys
import os
import pandas as pd
import requests
from time import sleep
from scipy.spatial import Delaunay
from threading import Lock
import pickle
from pathlib import Path
import openrouteservice
import json

I have the following questions:
1. What do the first lines do?
2. Can I get rid of them to run the script on Windows?
3. How do I check which packages I need to run it? Trial and error until it runs?

Thank you.
