Showing pop up message to show the error message when the code stops running WXPYTHON

Question

I am new in wxpython. Is there any way to show pop up message to show the error message when the code stops running? So the user doesn't need to look at the terminal to see that actually the code stops.

Thanks!

Just to illustrate the comment from @Michael Butscher and the answer from @Dan A.S.

You can use sys and traceback to catch and display the event in a wx.MessageDialog

import wx
import sys, traceback

def my_message(exception_type, exception_value, exception_traceback):
    msg = "Oh no! An error has occurred.\n\n"
    tb= traceback.format_exception(exception_type, exception_value, exception_traceback)
    for i in tb:
        msg += i
    dlg=wx.MessageDialog(None, msg, str(exception_type), wx.OK|wx.ICON_INFORMATION)
    dlg.ShowModal()
    dlg.Destroy()

sys.excepthook = my_message

class MyFrame(wx.Frame):
    def __init__(self, parent, id=wx.ID_ANY, title="", size=(360,100)):
        super(MyFrame, self).__init__(parent, id, title, size)
        self.panel = wx.Panel(self)
        self.panel.Bind(wx.EVT_KEY_DOWN, self.OnKey)
        self.Show()

    def OnKey(self, event):
        print ("alpha" + 1)

if __name__ == "__main__":
    app = wx.App()
    frame = MyFrame(None,title="Press a key")
    app.MainLoop()
