In this step-by-step tutorial, you'll learn how to build a mobile application with Python and the Kivy GUI framework. You'll discover how to develop an application that can run on your desktop as well as your phone. Then, you'll package your app for iOS, Android, Windows, and macOS. Here are the steps to install XCode, HomeBrew as well as install Python 3 using HomeBrew onto your Mac: Jump into your Terminal app on your Mac and run the copy/paste the following command into the Terminal to install XCode onto your Mac: $ xcode-select -install; Simply click through all the confirmation crap that XCode shows. The Python class representing your extension. The Python class is where you write your business logic for the extension. This class is important because it is called when the application extension is used in a desktop application. Use the Python naming convention when constructing your class. Python classes use cap-word notation. Swift is a robust and intuitive programming language created by Apple for building apps for iOS, Mac, Apple TV, and Apple Watch. It’s designed to give developers more freedom than ever. Swift is easy to use and open source, so anyone with an idea can create something incredible.
In this tutorial we’ll be using py2app to create a standalone OSX application from a Python 2 or 3 source code with asimple Tkinter user interface.
'py2app is a Python setuptools command which will allow you to make standalone application bundles and plugins from Python scripts. py2app is similar in purpose and design to py2exe for Windows.'
Relevant links about py2app:
- Source on BitBucket (last commit 2015-05-05)
- Issue Tracker, Mailing List
This guide is loosely based on the official tutorial.Based on a Python file called
Sandwich.py
, we’ll create an application called Sandwich.app
.Prerequisites
Create a custom directory and create a virtualenv:
Now create a very simple Tkinter app with the filename
Sandwich.py
:What to do when a mac app hangs. What to do when an app hangs in OS X. When an application hangs in OS X you might resort to forcing it to quit, but there are some other approaches you can try before doing this.
This little app will look like this:
Install py2app
![Mac Desktop App Python Mac Desktop App Python](/uploads/1/3/4/2/134201371/227480819.jpg)
The original version of py2app has a bug due to a newer version of ModuleGraph. Imade a fork of the project and fixed this bug on Github.Install it with pip like this:
The method you'll need to scan a document on a Mac depends on what kind of scanner you have. Here's how to set up nearly any scanner on a Mac. What app does mac use for scanning. IScanner will turn your device into a powerful digital office and help you become more productive in your work and daily life. Download this scanner app for free to instantly scan, save, and share any document in PDF, JPG or TXT formats. Go paperless with our fast PDF scanner – store all your documents in a neat mobile office right on your phone! On the Mac, open Finder, click Go in the top menu bar, and then click Applications. Double-click the HP folder, and then double-click HP Utility. Note: If you cannot find HP Utility, try scanning with another app or method, such as HP Easy Scan or Scan to Email.
Create a setup.py
file
py2app includes
py2applet
, a helper which generates a setup.py file for you:This
setup.py
is a basic definition of the app:If your application uses some data files, like a JSON, text files or images, you should include them in DATA_FILES. For example:
Build the app for development and testing
py2app builds the standalone application based on the definition in
setup.py
.For testing and development, py2app provides an “alias mode”, which builds anapp with symbolic links to the development files:
This creates the following files and directories:
This is not a standalone application, and the applications built in alias mode are not portable to other machines!
The app built with alias mode simply references the original code files, so any changes you make to the original
Sandwich.py
file are instantly available on the next app start.The resulting development app in
dist/Sandwich.app
can be opened just like any other .app with the Finderor the open command ($ open dist/Sandwich.app
). To run your application directly from the Terminalyou can just run:Building for deployment
When everything is tested you can produce a build for deployment with a calling
python setup.py py2app
. Make sure that any old build
and dist
directories are removed:This will assemble your application as
dist/Sandwich.app
. Since this application is self-contained, you will have to run the py2app command again any time you change any source code, data files, options, etc.The original py2app has a bug which would display “
AttributeError: 'ModuleGraph' object has no attribute 'scan_code'
” or load_module
. If you encounter this error, takea look at this StackOverflow thread or use my fork of py2app.The easiest way to wrap your application up for distribution at this point is simply to right-click the application from Finder and choose “Create Archive”.
Adding an icon
Simply add
'iconfile': 'youricon.icns'
to the OPTIONS
dict:You can find free icons in icns format around the web (eg. on IconFinder or freepik).
Advanced app settings
You can tweak the application information and behaviour with modificationsto the
Info.plist
. The most complete reference for the keys available is Apple’s Runtime Configuration Guidelines.Here is an example with more modifications:
With these settings, the app will have the following infos:

Over its almost 30 years of existence, Python has become one of the most popular programming languages. But if most startups once used it because of its simplicity and low cost, modern giants like Instagram or Spotify use Python and the Django framework to create smooth working experiences. As one of the most popular web development frameworks, famously, Django provides fast work processes, clean design, and transparent functionality, among many other advantages. It allows developers at all levels to focus on writing their apps instead of reinventing the wheel (or fixing it, for that matter). On top of that, it’s free, open source, and has gathered a mighty community of developers over the years. Large companies appreciate this. To give you an example, let’s take a look at some apps written in Python that you probably didn’t know about.
1. Instagram
As you know, this is the app that changed the world of digital photography, made it instant, more accessible and widespread, expanded lines of creativity and defined new rules in marketing. It allows users to take pictures, edit and share them online using a camera as simple as a smartphone. With 400 million active users per day, it obviously negates any notion that apps built in Python are not really scalable. According to Instagram engineer Hui Ding, Instagram’s engineering motto is “Do the simple things first” – and this is what Python allows developers to do. For them, it’s user-friendly, simple, clean, and favors pure pragmatism. And since it’s so popular, growing an engineering team is a lot easier.
2. Pinterest
Mac Desktop App Python App
Ranking third behind Facebook and Twitter, Pinterest is a social network that allows users to bookmark images, collect and share them with other users. As one of the web’s most-used apps, Pinterest relies on Python and Django to rapidly deal with large amounts of content. In fact, this website has used Python since day one.
3. Disqus
This commenting plug-in is a simple and effective way to engage an audience and fuel discussion while controlling incoming content by efficiently moderating the comments. Allowing multiple sign-in options and cross-site notifications, this app serves audiences with all kinds of preferences. In this case, Python makes full use of Django’s security features and regular security patches.

4. Spotify
Python Apps Examples
Spotify is the world’s largest streaming service, with an annual revenue of over €4 billion. This makes it a major market player and also one of the top Python users among businesses. The company preferred Python development because of its speed and advanced data analytics that the language offers. This enables Spotify to manage functions such as Radio and Discover, which are based on the personal musical preferences of users.

5. Dropbox
Another top app built in Python is Dropbox. The popular file-hosting service recently moved from Python 2.7 to Python 3 in one of the largest Python 3 migrations ever. One of the most popular desktop apps in the world, Dropbox can be installed on Windows, macOS, and some flavors of Linux. It’s a good thing that Python is portable and works on many platforms, from PC and Linux to PlayStation.
6. Uber
A ride-hailing service that also offers food delivery, peer-to-peer ridesharing and bicycle-sharing (among other services), Uber has a lot of calculations to do. Think about it: the company operates in 785 metropolitan areas worldwide and is estimated to have 100 million users. That’s a lot of math. But again, Python handles large amounts of data and is easy to learn and work with, which are two reasons why Python is so popular. These benefits make it an obvious choice for companies whose applications need to be reliable, secure and rely on developers around the world to maintain it.
7. Reddit
The American social news aggregator and discussion website Reddit also runs on Python, even though originally it was written in Common Lisp. After looking for wider access to code libraries and greater development flexibility, Reddit made the switch. If you look at it, this website is somewhat of an anthill. With about 542 million monthly visitors as of February 2018, Reddit is one of the most impressive Python app examples. Registered users post content such as text, video, or images in thousands of categories, and vote it up and down. Using a localization management platform, users help translate Reddit into 89 different languages. Again, Python manages the workload and complex functionality thanks to its “batteries included” approach.

What can we say? That’s a powerful portfolio! As we mentioned earlier, Python used to be a language for rough drafts and startup development because it was simple and cheap. But usually, the simplest solutions are the most reliable ones. The more parts a mechanism has, the higher the chances of something breaking or someone messing up – which many large companies learned the hard way. That’s why they chose to work with Python, and why so many of the world’s most popular apps are built in Python. Python has proven that you can build an amazing product with simple, time-honored tools – as long as you create it for the users and don’t have to dig into overcomplicated code. (Unless, of course, you want to.)
