How to execute 2 functions at the same time?

Question

Python

I wrote the code, built it into the tray from wxPython (when you click the item in the tray, the code starts), but it contains a while isWorking == 1 loop, because of which, until one of it ends, you won’t be able to open the tray (because in wxPython the tray is opened through the function ) and change the value of isWorking to 0 too, because in my code it also changes by clicking the item in the tray. How can you implement the parallel execution of several functions and getting the value of a variable by the 1st function from another?

The code:

import keyboard as kb
import soundfile as sf
import soundcard as sc
import wx
import wx.adv

TRAY_TOOLTIP = 'Papich keyboard'
TRAY_ICON = 'icon.png'
KeyBind = 'F9'
StopKeyBind = 'F10'
isWorking = 0

def create_menu_item(menu, label, func):
  item = wx.MenuItem(menu, -1, label)
  menu.Bind(wx.EVT_MENU, func, id=item.GetId())
  menu.Append(item)
  return item


class TaskBarIcon(wx.adv.TaskBarIcon):
  def __init__(self, frame):
    wx.adv.TaskBarIcon.__init__(self)
    self.myapp_frame = frame
    self.set_icon(TRAY_ICON)
    self.Bind(wx.adv.EVT_TASKBAR_LEFT_DOWN, self.on_left_down)

  def CreatePopupMenu(self):
    menu = wx.Menu()
    create_menu_item(menu, 'Say Hello', self.on_hello)
    menu.AppendSeparator()
    create_menu_item(menu, 'Exit', self.on_exit)
    create_menu_item(menu, 'Start ('+KeyBind+')', self.on_start)
    create_menu_item(menu,'STOP ('+StopKeyBind+')', self.on_stop)
    return menu

  def set_icon(self, path):
    icon = wx.Icon(wx.Bitmap(path))
    self.SetIcon(icon, TRAY_TOOLTIP)

  def on_left_down(self, event):
    print('Tray icon was left-clicked.')

  def on_hello(self, event):
    print('Hello, world!')

  def on_exit(self, event):
    self.myapp_frame.Close()

  def on_start(self, event):
    isWorking = 1
    while isWorking == 1:

Buddy-pie, are you sure that you need while True: when checking keys?
I myself did not try to do anything with the interface, but logically, you have a main room ... loop ... looped! Yes, fixated, here.
And in theory, until the main is completed, he will constantly check the keys anyway, isn't he?
Try it, report the results, it's already interesting for yourself.
