A single instance usage analysis of the Python implementation program

This example describes a single instance usage of the Python implementation program. Share to everyone for your reference. Specific as follows:

Here, use Win32ui first. FindWindow finds the window name and throws an exception if it does not exist

Import wximport Win32ui Import Win32con try:   # First Find out if the program has run  win = Win32ui. FindWindow (None, ' window name ')  try:     if win:       win. ShowWindow (Win32con.sw_shownormal)  except:     pass except:   # did not find the relevant window   app = wx. APP ()   main_frm = wx. Frame (None)  main_frm. Show ()   app. Mainloop ()

If the ' Window name ' section is undefined, a new window is created.

Hopefully this article will help you with Python programming.
