How to open Notepad application using Python

This article explains how to use Python to open the Notepad application on Windows. This method is helpful when automating application launching tasks through Python code.

In this article, we will use Python’s subprocess module to open the Notepad application on a Windows system. This method allows you to launch any external program from Python easily.

Python Code

import subprocess

# Use subprocess to open Notepad
subprocess.Popen(['notepad.exe'])

Detailed explanation:

1. import subprocess: This line imports Python’s subprocess module, which allows interaction with the operating system to run external applications.
2. subprocess.Popen(['notepad.exe']): This method uses Popen to open the Notepad application. notepad.exe is the executable file name for Notepad on Windows.

System requirements:

• Python 3.x
• Windows operating system

How to install the libraries needed to run the Python code above:

No external libraries are needed; subprocess is a built-in Python module.

Tips:

• Ensure the application name is correct. On non-Windows systems, you may need to specify the proper path or the corresponding application for that OS.
• You can use subprocess.Popen to open other applications by replacing the application name in the command.
