When running a python script in IDLE, is there a way to pass in command line arguments (args)?

Question

I\'m testing some python code that parses command line input. Is there a way to pass this input in through IDLE? Currently I\'m saving in the IDLE editor and running from a

Command-line arguments have been added to IDLE in Python 3.7.4+. To auto-detect (any and older) versions of IDLE, and prompt for command-line argument values, you may paste (something like) this into the beginning of your code:

#! /usr/bin/env python3

import sys

def ok(x=None):
      sys.argv.extend(e.get().split())
      root.destroy()


if 'idlelib.rpc' in sys.modules:

      import tkinter as tk

      root = tk.Tk()
      tk.Label(root, text="Command-line Arguments:").pack()

      e = tk.Entry(root)
      e.pack(padx=5)

      tk.Button(root, text="OK", command=ok,
                default=tk.ACTIVE).pack(pady=5)

      root.bind("", ok)
      root.bind("", lambda x: root.destroy())

      e.focus()
      root.wait_window()

You would follow that with your regular code. ie. print(sys.argv)

Note that with IDLE in Python 3.7.4+, when using the Run... Customized command, it is NOT necessary to import sys to access argv.

If used in python 2.6/2.7 then be sure to capitalize: import Tkinter as tk

For this example I've tried to strike a happy balance between features & brevity. Feel free to add or take away features, as needed!
