Ms visual studio python4/7/2024 ![]() Question: What other Python templates does Visual Studio offer?Īnswer: With the Python workload installed, Visual Studio provides a variety of project templates including ones for the Flask, Bottle, and Django web frameworks, Azure cloud services, different machine learning scenarios, and even a template to create a project from an existing folder structure containing a Python app. Such code allows you to easily control the configuration on both development and production machines without changing the code: if _name_ = '_main_': The startup code below allows you to set the host and port through environment variables rather than hard-coding them. All of the code shown here is created by the template, so you don't need to paste any into app.py yourself. Open app.py to see that the template has provided code like that in Quickstart - Create a web app with Flask, with a few added sections. Select Debug > Start without Debugging to run the app and open a browser to localhost:5555.Īfter Visual Studio creates that environment, look in Solution Explorer to see that you have an app.py file along with requirements.txt. HOST = os.environ.get('SERVER_HOST', 'localhost') Then comes route decorator on a simple function that defines a view: hello():įinally, the following startup code allows you to set the host and port through environment variables rather than hard-coding them. Next is the following line that can be helpful when deploying an app to a web host: wsgi_app = app.wsgi_app The code begins with the necessary imports: from flask import Flask All of the code shown here's created by the template, so you don't need to paste any into app.py yourself. For more information on virtual environments and their benefits, see Use virtual environments and Manage required packages with requirements.txt.Īfter Visual Studio creates that environment, look in Solution Explorer to see that you have an app.py file along with requirements.txt. You can then easily generate a requirements.txt file, which you use to reinstall those dependencies on other development computers (as when using source control) and when deploying the project to a production server. ![]() Virtual environments maintain your project's exact requirements over time as you add and remove libraries. When you begin a project, it's highly recommended to create a virtual environment right away, as most Visual Studio templates invite you to do.
