Installs tools for web development including HTML, CSS, and JavaScript editing support, along with templates for projects using the Bottle, Flask, and Django frameworks. Installs the Cookiecutter graphical UI to discover templates, input template options, and create projects and files. Also, if a newer version of Python is available than what's shown in the installer, you can install that version separately and Visual Studio will detect it. Visual Studio automatically detects existing Python installations. (You can return to the Visual Studio installer at any time to add or remove distributions.) Note: If you've installed a distribution outside of the Visual Studio installer, there's no need to check the equivalent option here.
Anaconda, specifically, is an open data science platform that includes a wide range of pre-installed packages. Each includes the distribution's interpreter, runtime, and libraries. Choose any combination of the available options, such as 32-bit and 64-bit variants of the Python 2, Python 3, Miniconda, Anaconda2, and Anaconda3 distributions that you plan to work with.
