Do you want to know how Python runs? It sounds simple, but it can actually be difficult to find out. This post explains how to test your Python code and run Python in other contexts: for example, online or as a packaged app.
Sometimes the thing that is holding you back from learning to code can be extremely simple. I remember wanting to learn how to program when I was younger – or learned to apply what I learned from BASIC on the ZX Spectrum to a modern environment. My problem? I didn’t know where to program. If I understood C # or Java, where would I enter the code and how would I run it?
And when I asked someone, they looked at me blankly. Whats that for a question?
I had never needed an IDE or an interpreter before. Machines like the ZX Spectrum and Tatung Einstein (any other Einstein users out there?) Just started up with a prompt to code!
Many people have a similar problem with Python. You understand the code but 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 be confusing at times to just run a lot of code.
Then read on and learn how to run Python in any situation!
How to run Python apps
Before we dive into running Python, the first thing you need to do is to install the Python interpreter on your computer. You can find this under the following links:
We also previously wrote guides on how to install Python and start coding on Windows, Mac, or Linux.
However, this only shows you how to install the interpreter. This will teach your computer understand Python, but it gives you nowhere to enter and run apps.
Except that’s not necessarily true. After installing this package, look for the Python Shell program. This gives you a shell in which you can enter Python commands directly and execute them immediately. Once you hit Enter, the instruction you used will be executed.
But go to File> New File and you can create a new .py file! Enter a code here and go to: Run> Run module. You will be asked to save your file as a module (a compact piece of Python code that can be executed by other scripts) and from there your app will run!
How to run Python files.
Conversely, you can also run Python files with various IDEs or editors. An IDE is an integrated development environment that gives you an interface through which you can enter your code, test your apps, and view any typing errors.
How to create Python executables
Now that you know how to run Python files, what if you want to help other people run your programs? Most of the non-coding people don’t have Python installed on their computer, let alone access to an IDE or editor! If you ever plan to share or sell your creations, this is a hurdle to overcome.
Unfortunately, there is no built-in way to make Python files executable on any computer. That’s because Python is a dynamic language, which is different from, for example, C #. Some developers get around this by including Python as part of the download, but that’s hardly an elegant solution.
Fortunately, there are third-party solutions. Two popular options are PyInstaller and Py2exe. Either allows you to create new apps as EXE files. To download and use them you will need to use PiP.
Simply enter the following to install PyPI’s PyInstaller on Linux or Mac:
pip install pyinstaller
To do the same thing through Windows, run Command Prompt (make sure you’re running as administrator), then use:
py -m pip install pyinstaller
If you don’t have pip installed, you can usually do so by modifying your Python installation (search uninstall in your search bar, then select your Python version and select “Modify”).
There are a few additional steps you need to take to use either of these tools and actually create your EXE file. However, all relevant instructions can be found on their respective websites.
How to run Python web applications
One thing you’ll notice when trying to create an .exe file from your Python code is that it’s not an intuitive or smooth process. That’s because Python isn’t really that to the.
Python is typically used more often to create useful tools for IT professionals, such as: B. Information security specialists. However, it’s also extremely useful for building web apps. In other words, Python is great if you’re looking to build the next Google, Twitter, or Spotify. In this scenario, Python is running on a server and displaying information to the visitor through the browser. Since the code runs on the server, the user does not need to install Python. It also means that the user will not slow down.
But what is that? Likewise This means that you will need to take the time to install Python on your browser. You will likely need to install a web framework as well. A web framework provides packages and modules that you can use to easily build web applications using Python code. These frameworks do the heavy lifting for you by simplifying a variety of common functions that are required in web design. This can include things like database searches, handling cookies, displaying images, and more.
There are many options if you are interested in Python web frameworks. A good choice for beginners is Flask. This is a very lightweight “micro-framework”, but it is also relatively simple compared to many other options.
Here is a great tutorial that I found online that can help you get started:
Here you can get Flask and documentation on how to use it.
Other good options are Django and Web2py. As always, these each have their own strengths and weaknesses so you need to find the right option for your intended purposes.
How to run Python on mobile devices
The easiest way to run Python on mobile devices is to download an IDE on the platform you choose. There is no need to download a separate interpreter. You can just download the app and start entering and running your Python code. Two great options are:
If you want to build apps that you can distribute to mobile devices using Python, you should probably 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.
Here you go! This is how you can run Python on different platforms. Obviously, you will need to do some tinkering in order for some of these options to work (e.g. web or mobile apps) but this post should give you a good idea of where to start.
And now you know how to use your Python code. Maybe you are ready to start building some apps? In that case, you should check out our guide to the best Python courses online.
