The source code for both the apps (Python file, APK, and buildozer spec) can be found at this GitHub repository. If you don’t want to use the APK generated into your devices then you simply host them online using a free service called Appetize.io which allows you to run android apps in browsers!
A lot of people want to learn python programming until they found all courses online made with laptops and desktops. so, they get disappointed and lose interest in learning. Today, I decided to help you with this problem and show you how you can run python on mobile phone.
Imagine building and running python applications, whether it's a command-line tool developed to fetch your favorite curated articles from the Internet, or starting a web server that runs right in the palm of your hand, all with just an Android mobile device and open source tools. Getting Started¶. Getting up and running on python-for-android (p4a) is a simple process and should only take you a couple of minutes. We’ll refer to Python for android as p4a in this documentation. Your Android emulator now is ready to run your custom Python script, so let's create one. Before you do though, note that the published SL4A API is a subset of the full Android API, so certain features either are not available, in the process of being made available or fully supported (see Resources for a link to the current list).
Using Mobile Apps IDE
The first way is using mobile applications ( python mobile IDE ) to run python codes on.
Python IDE for android
We start with android mobiles .

Termux
Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required. A minimal base system is installed automatically - additional packages are available using the APT package manager.
Simply termux makes your phone like a pc . so you can install python on your phone and run scripts.
I personally use it to serve website on my android phone. or to run scripts.
We will use termux only to run python files on phone. And Acode app to write the code.

How to use termux and acode to run python file on android
After installing termux and Acode. open Acode create new file and name it code.py then save it. After that go to parameters and give termux access to storage then open termux then run
then
then
to see all files in home storage so you copy your file to this location and run

Conclusion
If you want to do something just stick on it and don't let anything stops you.
happy coding on your phones.
Now, we’re going to take our application, and deploy it as an Androidapplication.
The process of deploying an application to Android is very similar to theprocess for deploying as a desktop application. Briefcase handles installingdependencies for Android, including the Android SDK, the Android emulator, anda Java compiler.
Create an Android app and compile it¶
Python Interpreter
First, run the create command. This downloads an Android app template andadds your Python code to it.
When you run briefcasecreateandroid for the first time, Briefcasedownloads a Java JDK, and the Android SDK. File sizes and download times can beconsiderable; this may take a while (10 minutes or longer, depending on thespeed of your Internet connection). When the download has completed, you willbe prompted to accept Google’s Android SDK license.
Once this completes, we’ll now have an android directory in our project.This directory will contain a HelloWorld folder, which will contain anAndroid project with a Gradle build configuration. This project will containyour application code, and a support package containing the Python interpreter.
We can then use Briefcase’s build command to compile this into an AndroidAPK app file.
Gradle may look stuck
During the briefcasebuildandroid step, Gradle (the Android platformbuild tool) will print CONFIGURING:100%, and appear to be doing nothing.Don’t worry, it’s not stuck - it’s downloading more Android SDK components.Depending on your Internet connection speed, this may take another 10 minutes(or longer). This lag should only happen the very first time you runbuild; the tools are cached, and on your next build, the cached versionswill be used.
Run the app on a virtual device¶
We’re now ready to run our application. You can use Briefcase’s run commandto run the app on an Android device. Let’s start by running on an Androidemulator.
To run your application, run briefcaserunandroid. When you do this,you’ll be prompted with a list of devices that you could run the app on. Thelast item will always be an option to create a new Android emulator.
We can now choose our desired device. Select the “Create a new Androidemulator” option, and accept the default choice for the device name(beePhone).
Web Python Runner
Briefcase run will automatically boot the virtual device. When the deviceis booting, you will see the Android logo:
Android virtual device booting¶
Once the device has finished booting, Briefcase will install your app on thedevice. You will briefly see a launcher screen:
Android virtual device fully started, on the launcher screen¶
The app will then start. You’ll see a splash screen while the app starts up:
The first time the app starts, it needs to unpack itself onto the device. Thismay take a few seconds. Once it’s unpacked, you’ll see the Android version ofour desktop app:
Demo app fully launched¶
Python Runner For Android
If you fail to see your app launching, you may need to check your terminalwhere you ran briefcaserun and look for any error messages.
In future, if you want to run on this device without using the menu, you canprovide the emulator’s name to Briefcase, using briefcaserunandroid-d@beePhone to run on the virtual device directly.
Run the app on a physical device¶
If you have a physical Android phone or tablet, you can connect it to yourcomputer with a USB cable, and then use the Briefcase to target your physicaldevice.
If Briefcase can detect the device, it will appear in the run output. Thefirst time you use a device for development, it may report itself as an“Unknown device (not authorized for development)”:
Android requires that devices be placed into “developer” mode before you canload an app onto the device. Select the “unknown” device, and you’ll be showna link that shows you how to enable developer mode.
Once developer mode has been enabled you can re-run briefcaserunandroid:
This time, we get the name of the device, and it’s serial number (in this case,a Pixel 3a).
In the future, if you want to run on this device without using the menu, you canprovide the phones’s serial number to Briefcase, using briefcaserunandroid-d94ZZY0LNE8. Thi will run on the device directly, wthout prompting.
Note
When you’re developing for Android, it’s useful to be able to view theAndroid logs. To view the Android logs without the background noise fromthe rest of the system, you can run adblogcat-sMainActivity:*stdio:*Python:*. Anything your app writes to stdout (e.g., the output ofprint() statements) will be visible in the logs.
