问题
Hello I am making a Python Tkinter GUI program but as I was making it I noticed that a small Tkinter window pops up then closes before the main window pops up. It is very distracting and obviously something that you would have in a professional piece of software. Here is an example of the problem:
from tkinter import *
app = Tk()
app.title("My GUI")
app.iconbitmap(r"C:\Program Files (x86)\Notepad++\Files\journalicon.ico")
app.resizable(0,0)
button = Button(text = "Text")
button.pack()
app.mainloop()
The iconbitmap option was something I found from another stack overflow page and used it. If you know of a better option I would appreciate the help. I am quite lost and would really appreciate any answers.

Try this:
app = Tk()
app.title("My GUI")
app.iconbitmap(app, "C:\Program Files (x86)\Notepad++\Files\icon.ico")
app.resizable(0,0)
app.mainloop()
You let tkinter know that the definition for things inside the window have stopped by calling mainloop. I have defined the window for the iconbitmap when it is called, using "(app, .."
Hope this helps!
