How to Launch Computer Programs Using Python



Python


In this article, we show how to launch computer programs using Python.

A Python script can start other programs on your computer.

For example, it can open up the calculator (to do calculations) or it can open up notepad (so that you can write a document). Or it can open up a sound file that can be played.

Python has the low-level functionality to be able to open up any program on your operating, just as if you had double-clicked on it (to get it started).

You can do this in Python using the subprocess.Popen() function.

Using this function, all you have to do is pass in the program that you want to open up in its parameters.

Let's go over some examples below.
