[Tutor] Really basic won't run error

[Phil]

I've been working on this idea for most of the day and have finally 
reduced the problem to a wxPython demo example but it won't run. No 
doubt the reason is obvious but I cannot see it.

import wx

class ImagePanel(wx.Panel):
     def __init__(self, parent):
         wx.Panel.__init__(self, parent, -1)#None, title="Bitmap test")

         wx.StaticText(self, -1, "This is a wx.StaticBitmap.", (45, 15))

         bmp = 'test.jpg'.GetBitmap()
         #mask = wx.Mask(bmp, wx.BLUE)
         #bmp.SetMask(mask)
         #StaticBitmap(self, -1, bmp, (80, 50), (bmp.GetWidth(), 
bmp.GetHeight()))

         StaticBitmap(self, -1, bmp, (80, 150))

if __name__ == "__main__":
     app = wx.App()
     frame = ImagePanel().Show()
     app.MainLoop()

Traceback (most recent call last):
   File "/usr/lib/python3.8/idlelib/run.py", line 559, in runcode
     exec(code, self.locals)
   File "/home/phil/Python/wxpython_bitmap.py", line 38, in <module>
     frame = MyFrame().Show()
TypeError: __init__() missing 1 required positional argument: 'parent'
