Python 3 will be the only Python version installed by default. Python 3 will be the only Python version in any installation media (i.e. image ISOs) Only Python 3 will be allowed on the Ubuntu touch images. All upstream libraries that support Python 3 will have their Python 3 version available in the archive.

When you need each Python 3 application that you are building to run in its own isolated environment, you can turn to virtual environments. Since Python is available on Windows 10, you can also use virtual environments on Windows 10.Typically, using a Python 3 virtual environment in Windows 10 involves the following steps:Installing Python 3 with pip and several features.Creating a Python 3 virtual environment with Python 3 venv module.Activating the Python 3 virtual environment.Installing Python 3 packages that your Python application is using into the virtual environment.Running your Python 3 application within the Python 3 virtual environment.Deactivating the Python 3 virtual environment.1. Installing Python 3 with pip and several features on Windows 10When you head over to the Python 3 download page for windows, you will find several options:Next, determine whether your Windows 10 operating is 32 bit or 64 bit. When you have a 32 bit operating system, download the latest executable installer with x86. However, if you have a 64 bit operating system, download the one with x86-64. For example, if I have Windows 10 64 bit, I can download Windows x86-64 executable installer for Python 3.7.1 runtime.After you had downloaded the Python 3 installer, double-click on it. Choose to Add Python 3.7 to PATH: Left-click on Customize installation. After the next screen appears, check pip:Left-click on Next and the Advanced Options screen appears:Finally, left-click on Install to start the installation progress:When the installation had completed, you will see the following screen:Left-click on Close to exit the installation wizard.2. Creating a Python 3 virtual environment with Python 3 venv module on Windows 10When you had installed Python 3 on Windows 10, you can then create the virtual environment for your Python 3 application. In order to do so, open up a command prompt window and type the following command:python -m venv %systemdrive%%homepath%\my-venvAfter the command completes, you will find the my-venv directory inside your home directory. Inside the my-venv, you will find the Python artefacts to work with your virtual environment.3. Activating your Python 3 virtual environment on Windows 10Before you can run your Python 3 application inside of your Python 3 virtual environment, you will need to activate it. In order to activate your virtual environment, you will need to run the activate.bat script located inside your virtual environment directory. For example, to activate the virtual environment inside my-venv, you can run the following command in your command prompt window:%systemdrive%%homepath%\my-venv\Scripts\activate.batAfter the activate.bat script had ran, you will see the prompt appended with (my-venv):This tells us that the command prompt session is inside the Python 3 virtual environment.4. Installing Python 3 packages that your Python application is using into the virtual environment.When you had activated your virtual environment,. Python 3 will be the only Python version installed by default. Python 3 will be the only Python version in any installation media (i.e. image ISOs) Only Python 3 will be allowed on the Ubuntu touch images. All upstream libraries that support Python 3 will have their Python 3 version available in the archive.

For example, you can install the requests library for your Python 3 application to download a file from a HTTP server or upload a file to a HTTP server:pip install requestsIn order to use the pip command, you need to ensure that you had installed it during your Python 3 installation.5.

Deactivating the Python 3 virtual environment on Windows 10When you want to get out of your Python 3 virtual environment on Windows 10, you can simply run the following command:deactivateAfter the virtual environment is deactivated, your command prompt will switch to the global Python 3 environment. In addition, those Python 3 dependencies that you had installed in your virtual environment will not be available.

Getting Started with Vernier LabQuest® and PythonThis guide shows you how to get started writing Python programs for your Vernier LabQuest®. The guide contains the following topics:Getting Started RequirementsInstall the LabQuest Drivers (Windows Only)Install Python 3Choose an IDEInstall the labquest PackageConfirm Installation of the labquest PackageDownload and Run an ExampleAbout the ExamplesNotes Regarding the labquest FunctionsTroubleshooting and NotesIf you are new to Python you should look over all of the steps. If you are familiar with Python you might just focus on installing the labquest package and downloading the examples.Getting Started RequirementsWe have developed a Python package called labquest that allows you to communicate with Vernier LabQuest devices via USB. This requires the following:A Vernier LabQuest Mini, LabQuest Stream, LabQuest 3, LabQuest 2, or LabQuest OriginalOne or more Labquest supported sensorsA Windows® 10 or macOS® computerAn installation of the LabQuest driver (Windows only)An installation of Python 3An installation of the Vernier labquest package for Python 3Install the Windows DriversTo communicate with LabQuest devices on Windows computers a driver must be installed. If you already have Vernier Graphical Analysis or Logger Pro software installed, you have the driver. If you do not have this Vernier software, the driver can be installed with either the free trial of Graphical Analysis Pro or the free demo version of Logger Pro software.Install Python 3The labquest package is designed to work with Python 3, it is not compatible with Python 2. In some cases, Python is pre-installed and shipped with your operating system. Use the following steps to check for Python 3 on your machine, and to install Python 3 if needed:Open your operating system's tool for executing commands (on Windows 10 this would be Command Prompt or Powershell, on a Mac this would be a Terminal window).Check to see if Python 3 is already installed on your machine by running the following command:python --versionIf the response is a version of Python 3, it is installed.If there is no response from the command, it is not installed.If the response is a version of Python 2, you will need to try a second command to check for Python 3. Run the following command:python3 --versionIf you have determined that Python 3 is not installed, follow these steps:Find and install the latest installer for Mac or Windows from python.org.When installing on Windows, be sure to modify the installation to enable the "Add Python to environment variables".
