Button in GUI linked to new python script

[blakefindlay]

If you can do something in Python you can have the button call the Python code that does the something. Starting with a crude way of doing things you could execute a shell command.

import os

def run_program():
    os.system('python my_python_program.py')

Button(root, text='Run My Program', command=run_program)

A cleaner way to do this is use subprocess. This can be very simple.

import subprocess

def run_program():
    subprocess.call(["python", "my_python_program.py"])

Button(root, text='Run My Program', command=run_program)

Or you can use subprocess.Popen() which returns a handle that you can use to monitor the subprocess. You can even open up pipes so you can communicate with the subprocess.

But maybe you don't need another process. Why do you think you need to start up another GUI? What are you trying to do?

Great thanks. I added in right before the subprocess.call but within the run_program function

root.destroy()

FYI, I am designing a rental form for ski equipment at work as that is our main rental and within this program I want the ability to open other less common rental forms like snowshoe and skates. This function suits it perfectly so thank you for the help
