Opening other Python 3 files using tkinter

Question

I am currently working on making a program using tkinter that when pressing a button it opens the Python program, however I am having some problems with it. I have tried using os.system('filename.py'). That opens the file, but then crashes the GUI, making the user have to restart the GUI. I have also tried importing it as a module but that just does the same as when using os.system.

Can anyone possibly help me open a Python file in a completely new window/terminal?

What do you mean with "crashes the gui"? Could you elaborate on that? — tobspr, Apr 23 '16 at 16:03
The GUI would stop responding but the code to the program that was being opened would go in to the terminal that was running the GUI — User592, Apr 23 '16 at 16:05
The GUI stops responding because `os.system()` waits for the _command_ given to complete before returning which temporarily prevents `tkinter`'s `mainloop` from processing any GUI events. You should use `subprocess.Popen` to run another Python script concurrently with the GUI. — martineau, Apr 23 '16 at 17:14

The problem is filename.py will not be recognised by your os. Instead of that use:

os.system('python filename.py')

This will successfully open your python file inside your GUI Hope this helps

Thanks that fixed the problem of it not responding, however the terminal would just open then close straight away. – User592 Apr 24 '16 at 16:34
That depends on the python file you are trying to run – Johny Jose Apr 24 '16 at 19:11
They are both files that run using the terminal and are text based, no tkinter or anything else used – User592 Apr 24 '16 at 19:32
