Question

I do not see why i am getting this error: Traceback (most recent call last): File ....\play_download.py", line 55, in url = values['-url-'] ~~~~~~^^^^^^^^^ KeyError: '-url-'

This error appears when I click on radio button download_video_with_yt_dlp

The values was read from the window with layout1, not the window with layout2, so there's no element with key '-url-', also no key '-folder-'.

The window with layout2 was initialized, not finalized, so you won't see it.

Example Code

import webbrowser
import PySimpleGUI as sg

def popup():
    layout = [
        [sg.Input(key='-url-')],
        [sg.Push(), sg.Button("OK"), sg.Button("Cancel")],
    ]
    window = sg.Window("URL", layout)
    while True:
        event, values = window.read()
        if event in (sg.WIN_CLOSED, "Cancel"):
            result = None
            break
        elif event == "OK":
            result = values['-url-'].strip()
            break
    window.close()
    return result

layout = [[sg.Button("Download", size=20)]]
window = sg.Window("Download", layout)
while True:
    event, values = window.read()
    if event == sg.WIN_CLOSED:
        break
    elif event == "Download":
        url = popup()
        if url:
            webbrowser.open(url)
window.close()
