tkinter window not showing up in Spyder

Question

I am trying to make a simple GUI with tkinter in Spyder 4.2.5 with Python 3.8.8. I have the following code:

import tkinter as tk

window = tk.Tk()

greeting = tk.Label(text='Hello, Tkinter')
greeting.pack()

When I type the code in the command prompt in Windows, a window pops up. HOwever, in Spyder I cannot see it. Is there any setting I need to change or a special output window to check?

Thanks in advance!

Answer 1

Ok, odd, but it seems that in Spyder it needed to add

window.mainloop()

to show up the window, although in command prompt it did not. I hope it helps others!
