Auto PY to EXE is an amazing application for making.exe file out of your project whether it is one.py file or any number of them. The application has a nice gui and looks like this: How to start Step 1. Mar 18, 2013 Visual Studio Code (Mac) - Setting up a Python Development Environment and Complete Overview - Duration: 1:15:44. Mac OS X Tutorials and App reviews from HowTech 113,864 views. Python is a fully interpreted application. To run python code you always need a python interpreter. To create an app, which I assume is a application that you can run on your computer by double clicking on it, like a.exe, you must make it into so. From the Shell dropdown menu select /usr/bin/python. Paste your Python code into the edit window and then pick File Save. By default, the app will be saved under $HOME/Applications and will appear.
In this 5-10 minute introduction to Visual Studio as a Python IDE, you create a simple Python web application based on the Flask framework. You create the project through discrete steps that help you learn about Visual Studio's basic features.
If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free. In the installer, make sure to select the Python development workload.

In this step-by-step tutorial, you'll learn how to build a mobile application with Python and the Kivy GUI framework. https://high-powerreview.weebly.com/mac-app-for-streaming-uverse.html. 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.
Create the project
The following steps create an empty project that serves as a container for the application:
- Open Visual Studio 2017.
- From the top menu bar, choose File > New > Project.
- In the New Project dialog box, enter 'Python Web Project' in the search field on the upper right, choose Web project in the middle list, give the project a name like 'HelloPython', then choose OK.If you don't see the Python project templates, run the Visual Studio Installer, select More > Modify, select the Python development workload, then choose Modify.
- The new project opens in Solution Explorer in the right pane. The project is empty at this point because it contains no other files.
- Open Visual Studio 2019.
- On the start screen, select Create a new project.
- In the Create a new project dialog box, enter 'Python web' in the search field at the top, choose Web Project in the middle list, then select Next:If you don't see the Python project templates, run the Visual Studio Installer, select More > Modify, select the Python development workload, then choose Modify.
- In the Configure your new project dialog that follows, enter 'HelloPython' for Project name, specify a location, and select Create. (The Solution name is automatically set to match the Project name.)
- The new project opens in Solution Explorer in the right pane. The project is empty at this point because it contains no other files.
Question: What's the advantage of creating a project in Visual Studio for a Python application?
Answer: Python applications are typically defined using only folders and files, but this simple structure can become burdensome as applications become larger and perhaps involve auto-generated files, JavaScript for web applications, and so on. A Visual Studio project helps manage this complexity. The project (a .pyproj file) identifies all the source and content files associated with your project, contains build information for each file, maintains the information to integrate with source-control systems, and helps you organize your application into logical components.

Answer: A Visual Studio solution is a container that helps you manage for one or more related projects as a group, and stores configuration settings that aren't specific to a project. Projects in a solution can also reference one another, such that running one project (a Python app) automatically builds a second project (such as a C++ extension used in the Python app).
Install the Flask library
Web apps in Python almost always use one of the many available Python libraries to handle low-level details like routing web requests and shaping responses. For this purpose, Visual Studio provides a variety of templates for web apps, one of which you use later in this Quickstart.
Here, you use the following steps to install the Flask library into the default 'global environment' that Visual Studio uses for this project.
- Expand the Python Environments node in the project to see the default environment for the project.
- Right-click the environment and select Install Python Package. This command opens the Python Environments window on the Packages tab.
- Enter 'flask' in the search field and select pip install flask from PyPI. Accept any prompts for administrator privileges and observe the Output window in Visual Studio for progress. (A prompt for elevation happens when the packages folder for the global environment is located within a protected area like C:Program Files.)
- Expand the Python Environments node in the project to see the default environment for the project.
- Right-click the environment and select Manage Python Packages... This command opens the Python Environments window on the Packages (PyPI) tab.
- Enter 'flask' in the search field. If Flask appears below the search box, you can skip this step. Otherwise select Run command: pip install flask. Accept any prompts for administrator privileges and observe the Output window in Visual Studio for progress. (A prompt for elevation happens when the packages folder for the global environment is located within a protected area like C:Program Files.)
- Once installed, the library appears in the environment in Solution Explorer, which means that you can make use of it in Python code.
Note
Instead of installing libraries in the global environment, developers typically create a 'virtual environment' in which to install libraries for a specific project. Visual Studio templates typically offer this option, as discussed in Quickstart - Create a Python project using a template.
Question: Where do I learn more about other available Python packages?
Answer: Visit the Python Package Index.
Add a code file
You're now ready to add a bit of Python code to implement a minimal web app.
- Right-click the project in Solution Explorer and select Add > New Item.
- In the dialog that appears, select Empty Python File, name it app.py, and select Add. Visual Studio automatically opens the file in an editor window.
- Copy the following code and paste it into app.py:
- You may have noticed that the Add > New Item dialog box displays many other types of files you can add to a Python project, including a Python class, a Python package, a Python unit test, web.config files, and more. In general, these item templates, as they're called, are a great way to quickly create files with useful boilerplate code.
Question: Where can I learn more about Flask?
Answer: Refer to the Flask documentation, starting with the Flask Quickstart.
Run the application
- Right-click app.py in Solution Explorer and select Set as startup file. This command identifies the code file to launch in Python when running the app.
- Right-click the project in Solution Explorer and select Properties. Then select the Debug tab and set the Port Number property to
4449
. This step ensures that Visual Studio launches a browser withlocalhost:4449
to match theapp.run
arguments in the code. - Select Debug > Start Without Debugging (Ctrl+F5), which saves changes to files and runs the app.
- A command window appears with the message Running in https://localhost:4449, and a browser window should open to
localhost:4449
where you see the message, 'Hello, Python!' The GET request also appears in the command window with a status of 200.If a browser does not open automatically, start the browser of your choice and navigate tolocalhost:4449
.If you see only the Python interactive shell in the command window, or if that window flashes on the screen briefly, ensure that you set app.py as the startup file in step 1 above. - Navigate to
localhost:4449/hello
to test that the decorator for the/hello
resource also works. Again, the GET request appears in the command window with a status of 200. Feel free to try some other URL as well to see that they show 404 status codes in the command window. - Close the command window to stop the app, then close the browser window.
Question: What's the difference between the Start Without Debugging command and Start Debugging?
Answer: You use Start Debugging to run the app in the context of the Visual Studio debugger, allowing you to set breakpoints, examine variables, and step through your code line by line. Apps may run slower in the debugger because of the various hooks that make debugging possible. Start Without Debugging, in contrast, runs the app directly as if you ran it from the command line, with no debugging context, and also automatically launches a browser and navigates to the URL specified in the project properties' Debug tab.
Next steps
Congratulations on running your first Python app from Visual Studio, in which you've learned a little about using Visual Studio as a Python IDE!
Because the steps you followed in this Quickstart are fairly generic, you've probably guessed that they can and should be automated. Such automation is the role of Visual Studio project templates. Go through Quickstart - Create a Python project using a template for a demonstration that creates a web app similar to the one you created in this article, but with fewer steps.

Want to know how to run Python? It sounds simple, but it can actually be tricky to figure this out. In this post, we’ll discuss how to test your Python code, as well as how to run Python in other contexts: online for example, or as a packaged app.
Sometimes, the thing holding you back from learning to code can be extremely simple. I remember wanting to learn to program when I was younger – or learning to take what I’d learned from BASIC on the ZX Spectrum and apply that to a modern environment. My problem? I didn’t know “where” to program. Once I understood C# or Java, where would I enter the code and how would I run it?
Mac Convert Python To Apply
And whenever I asked someone, they would look at me blankly. What kind of a question is that?
Thing is, I had never needed an IDE or an interpreter before. Machines like the ZX Spectrum and Tatung Einstein (any other Einstein users out there?) simply booted up with a prompt to code into!
Many people have a similar issue with Python. They understand the code, but they don’t know how to run Python. Or how to turn their creation into an app that someone can download and buy. In fact, with Python it can occasionally be confusing even just to run a bunch of code.
Read on then, and learn how to run Python in any situation!
How to run Python apps
Before we dive into how to run Python, you first need to install the Python interpreter on your machine. You can find that from the below links:
- Windows: https://www.python.org/downloads/windows/
- Mac: https://www.python.org/downloads/mac-osx/
- Linux:https://www.python.org/downloads/source/
Run Python On Mac
You can also find instructions on how to set this up and get it running here:
But this is only going to show you how to install the interpreter. This teaches your computer to understand Python, but it doesn’t give you anywhere to type and run apps.
Except that isn’t strictly true. Once you’ve installed this package, look for the program called Python Shell. This gives you a shell where you can type Python commands directly and have them run instantly. As soon as you press return, whatever statement you used will run.
But go to File > New File and you will be able to create a new .py file! Enter some code here, then go to: Run > Run Module. You’ll be prompted to save your file as a module (a compact piece of Python code that can be run from other scripts) and from there your app will run!
That is how to run Python files.
Python App Tutorial
Conversely, you can also run Python files using a number of different IDEs or editors. An IDE is an integrated development environment, which gives you an interface you can use to enter your code, test your apps, and see any errors you may have made while typing it out.
How to create executable Python files
Now you know how to run Python files, but what if you want to help other people to run your programs? Most people who don’t program won’t have Python installed on their machine, let alone access to an IDE or editor! If you ever plan on sharing or selling your creations, then this is a hurdle you will need to overcome.
Unfortunately, there is no built-in way to make Python files runnable on any machine. That’s because Python is a dynamic language unlike, say, like C#. Some creators get around this by including Python as part of the download, but that is hardly an elegant solution.
Fortunately, third-party solutions do exist. Two popular options are PyInstaller and Py2exe. Both of these will allow you to build new apps as .exe files. To download and use them, you will need to use PiP.
To install PyInstaller from PyPI on Linux or Mac, just type:
To do the same via Windows, run the command prompt (making sure to run as administrator) and then use:
If you don’t have pip installed, you can usually do this by modifying your Python installation (search uninstall in your search bar, then choose your Python version and choose “modify”).
You’ll need to follow some additional steps to use either of these tools and actually build your .exe but you will find all the relevant instructions on the respective websites.
How to run Python web apps
One thing you’ll notice when trying to build a .exe from your Python code, is that it is not an intuitive or smooth process. That’s because this isn’t really what Python is for.
Python is typically more often used to create useful tools for IT professionals, such as information security specialists. However, it is also extremely useful for building web apps. In other words, Python is great if you want to build the next Google, Twitter, or Spotify. In this scenario, Python will run on a server and then display information to the visitor through the browser. Because the code is executed on the server, that means there is no requirement for the user to have Python installed. It also means there will be no slow down for the user.
However, what this also means is that you need to take the time to install Python on your browser. You’ll also probably need to install a web framework. A web framework provides packages and modules that let you easily build web apps with Python code. These frameworks do the heavy lifting for you by simplifying a wide range of common functions necessary for web design. This may include things like database lookups, handling cookies, displaying images, and more.
There are plenty of options out there if you’re interested in Python web frameworks. A great choice for beginners is Flask. This is a very light “microframework,” but it is also relatively simple compared with many other options.
Here’s a great tutorial I found online that can help you to get started:
Here is where you can get Flask and some documentation on how to use it.
Other good options include Django and Web2py. As always, these each have their own strengths and weaknesses, so you’ll need to find the right option for your intended purposes.
How to run Python on mobile
If you want to run Python on mobile, one of the easiest options is simply to download an IDE on your chosen platform. There is no need to download a separate interpreter, you can simply download the app and start typing and running your Python code. Two great options are:
- iOS: Python3IDE
- Android: QPython 3L
If you want to make apps that you can distribute on mobile using Python though, you’ll probably want to use Kivy. Kivy is an open source library for rapid cross-platform development. It supports multi-touch, an OpenGL ES 2 graphics engine, and other useful features for mobile development and is completely free to use.
So there you go! That’s how to run Python on a variety of platforms. Of course, you’ll need to do some tinkering to get some of these options to work (like web or mobile apps), but this post should have given you a good idea of where to start.
And now you know how to use your Python code, perhaps you’re ready to start building some apps? In that case, you should check out our guide to the best online Python courses.
