3. Using Python on Windows Python

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,

The Python Releases for Mac OS X page and download the latest stable release macOS 64-bit/32-bit installer.After the download is complete, run the installer and click through the setup steps leaving all the pre-selected installation defaults.Once complete, we can check that Python was installed correctly by opening a Terminal and entering the command python3 --version. The Python 3.13.0 version number should print to the Terminal.Note: This version will change as new releases come out.Advanced Since our system now has both Python 2 (which came pre-installed) and Python 3, we must remember to use the python3 command (instead of just python) when running scripts. If you would rather not have to remember the python3 command and just use python instead, then creating a command alias is your best bet.Execute open ~/.bash_profile from a Terminal (if the file was not found, then run touch ~/.bash_profile first).Copy and paste alias python="python3" into the now open .bash_profile file and save.While we’re at it, go ahead and copy and paste alias pip="pip3" into the file as well in order to create an alias for the Python 3 pip package manager.Finally, restart the Terminal and run python --version. We should see the exact same output as running python3 --version.WindowsFollow the below steps to install Python 3 on Windows.Go to the Python Releases for Windows page and download the latest stable release Windows x86-64 executable installer.After the download is complete, run the installer.On the first page of the installer, be sure to select the “Add Python to PATH” option and click through the remaining setup steps leaving all the pre-select installation defaults.Once complete, we can check that Python was installed correctly by opening a Command Prompt (CMD or PowerShell) and entering the command python --version. The Python 3.13.0 version number should print to the console.Note: This version will change as new releases come out.Installing MinicondaMacFollow the below instructions to install the latest Miniconda version for Mac.Go to the Miniconda Download page and download the Python 3.13.0 Mac OS X 64-bit .pkg installer.Note: This version will change as new releases come out.After the download is complete, run the installer and click through the setup steps leaving all the pre-selected installation defaults.Once complete, we can check that Miniconda was installed correctly by opening a Terminal and entering the command conda list.

You can then install your Python 3 dependencies into your Python 3 virtual environment on Windows 10. 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. Running your Python 3 application within the Python 3 virtual environmentSubsequently, when you had installed all the needed dependencies, you can then run your Python 3 application with the python binary:python a_python_application.py6. 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.

Python for Beginners: Learn Python Programming (Python 3)

Information on this, see the Troubleshooting and Notes section of this guide.Choose an IDEWith Python installed, you need to choose an application that you will use to write and run your Python programs. You can write your programs in a simple text or code editor, or you can use an Integrated Development Environment (IDE). An IDE is a software application that provides all of the tools to write, comment, edit, debug, develop and run software programs. Python has an IDE bundled with it called IDLE that is cross-platform, and suitable for beginners. If you are new to Python and programming, we recommend that you start with this tool.Later, you may want to research the various IDEs, learn about the different features, and give one a try. For example, Visual Studio Code is a free IDE available for Windows and Mac. There are many other choices, and you can find more information at python.orgInstall the labquest PackageOnce you have Python 3 installed, you will use a tool called pip (a Python 3 package manager) to install the labquest package. Python automatically includes pip, so this tool is ready to use. Note that we will be using the pip3 command, rather than just pip, to ensure that the Vernier files will be associated with Python 3, and not Python 2.The pip3 commands are executed by running them in your operating systems’ tool for executing commands (Powershell, Command Prompt, or Terminal window). There are slight differences in the required steps to install the labquest module for Windows, and macOs. Follow the steps outlined below for your platform.Run the following command:pip3 install labquestConfirm Installation of the labquest PackageAt this point, you should have Python 3 installed and have the labquest package installed. Before moving to examples, confirm the installation of the labquest package by showing the version information. Run the following command in the terminal:pip3 show labquestRunning the pip3 show command will provide information about the installed package, including the version number.Should you need to update to a newer version in the future, run the following command in the terminal:pip3 install labquest --upgradeDownload and Run an ExampleWith the labquest package installed, it is time to run an example.Go to the github LabQuest examples page and download the files by clicking on the “Clone or download” green button and then clicking on the “Download ZIP” button.Locate the zip file in your download folder and extract/unzip
