Use subprocess to Run External Programs in Python 3 | DigitalOcean

How To Use subprocess to Run External Programs in Python 3

The author selected the COVID-19 Relief Fund to receive a donation as part of the Write for DOnations program.

Introduction

Python 3 includes the [subprocess](https://docs.python.org/3/library/subprocess.html) module for running external programs and reading their outputs in your Python code.

You might find subprocess useful if you want to use another program on your computer from within your Python code. For example, you might want to invoke [git](https://www.digitalocean.com/community/tutorials/how-to-contribute-to-open-source-getting-started-with-git) from within your Python code to retrieve files in your project that are tracked in git version control. Since any program you can access on your computer can be controlled by subprocess, the examples shown here will be applicable to any external program you might want to invoke from your Python code.

subprocess includes several classes and functions, but in this tutorial we’ll cover one of subprocess’s most useful functions: [subprocess.run](https://docs.python.org/3.7/library/subprocess.html#subprocess.run). We’ll review its different uses and main keyword arguments.

Prerequisites

To get the most out of this tutorial, it is recommended to have some familiarity with programming in Python 3. You can review these tutorials for the necessary background information:

Running an External Program

You can use the subprocess.run function to run an external program from your Python code. First, though, you need to import the subprocess and sys modules into your program:

import subprocess
import sys

result = subprocess.run([sys.executable, "-c", "print('ocean')"])

Automating WhatsApp Web with Alright and Python

Alright is a python wrapper that helps you automate WhatsApp web using python, giving you the capability to send messages, images, video, and files to both saved and unsaved contacts without having to rescan the QR code every time.

Why Alright?

I was looking for a way to control and automate WhatsApp web with Python; I came across some very nice libraries and wrappers implementations, including:

  1. pywhatkit
  2. pywhatsapp
  3. PyWhatsapp
  4. WebWhatsapp-Wrapper

So I tried

pywhatkit, a well crafted to be used, but its implementations require you to open a new browser tab and scan QR code every time you send a message, no matter if it’s the same person, which was a deal-breaker for using it.

I then tried

pywhatsapp,which is based onyowsupand require you to do some registration withyowsupbefore using it of which after a bit of googling, I got scared of having my number blocked. So I went for the next option.

I then went for WebWhatsapp-Wrapper. It has some good documentation and recent commits so I had hoped it is going to work. But It didn’t for me, and after having a couple of errors, I abandoned it to look for the next alternative.

PyWhatsapp by shauryauppal, which was more of a CLI tool than a wrapper, surprisingly worked. Its approach allows you to dynamically send WhatsApp messages to unsaved contacts without rescanning QR-code every time.

So what I did is refactoring the implementation of that tool to be more of a wrapper to easily allow people to run different scripts on top of it. Instead of just using it as a tool, I then thought of sharing the codebase with people who might struggle to do this as I did.

Python GUI Programming Projects using Tkinter and Python 3

Description
Learn Hands-On Python Programming By Creating Projects, GUIs and Graphics

Python is a dynamic modern object -oriented programming language
It is easy to learn and can be used to do a lot of things both big and small
Python is what is referred to as a high level language
Python is used in the industry for things like embedded software, web development, desktop applications, and even mobile apps!
SQL-Lite allows your applications to become even more powerful by storing, retrieving, and filtering through large data sets easily
If you want to learn to code, Python GUIs are the best way to start!

I designed this programming course to be easily understood by absolute beginners and young people. We start with basic Python programming concepts. Reinforce the same by developing Project and GUIs.

Why Python?

The Python coding language integrates well with other platforms – and runs on virtually all modern devices. If you’re new to coding, you can easily learn the basics in this fast and powerful coding environment. If you have experience with other computer languages, you’ll find Python simple and straightforward. This OSI-approved open-source language allows free use and distribution – even commercial distribution.

When and how do I start a career as a Python programmer?

In an independent third party survey, it has been revealed that the Python programming language is currently the most popular language for data scientists worldwide. This claim is substantiated by the Institute of Electrical and Electronic Engineers, which tracks programming languages by popularity. According to them, Python is the second most popular programming language this year for development on the web after Java.
