Python Forum

Hello,
first, i'm total newbie in programming. Started yesterday. I have trouble to understand how to open the coded python files. I have Tkinter import (with GUI) but when i try to open that .py file it opens cmd and then immediately closes. I know that i don't have any errors because I tried the same code in IDLE and everything worked perfectly. (I'm using Visual studio code program by the way).
Hope You understand
thanks!

python filename.py

Sorry but i didn't understand that well

Please show your code with tkinter.
It's hard to help without seeing what you are trying to do.
tkinter requires a minimum amount of code, like:

import tkinter as tk

root = tk.Tk()
root.title('My first app')
root.mainloop()
