How to open a program from my computer in python?

Im making a window in tkinter and I can't figure out how to run an external program in python. I am using the full path and am getting no errors, the file is just not loading.

I've tried os.startfile(path) but that doesn't open the file.

Here is my code:

from tkinter import *
from tkinter import ttk
import os

def run_selected():
    if ver.get() == "Test":

master = Tk()

ver = ttk.Combobox(master, state="readonly", values=["Test"])
Button(master, text="Run", command=run_selected).pack()


How do I fix this so that I can open the file?

EDIT: My (path) is "C:\Backup\Mindustry\Mindustry.exe"

    You can spawn a process using many different ways. Check here and here

    One of the ways could be

    import subprocess
    def run_selected():
        if ver.get() == "Test":
 [path], check=True)
           # e.g.["ls","-ltr"], check=True)

    However, since you are spawning it from Tkinter, you could spawn it from a different thread (unless process ends within milliseconds), else, the default Tkinter thread will get busy and the UI will appear frozen

    have you tried "import os"?

    import os os.startfile(path/
