Open Hello/_init_.py to see that it takes a name as input and returns a greeting. You've added the Hello activity function that is invoked by the orchestrator. Next, you'll add the referenced Hello activity function. Each call to context.call_activity invokes an activity function named Hello. Open HelloOrchestrator/_init_.py to see the orchestrator function. You've added an orchestrator to coordinate activity functions. In the command palette, search for and select Azure Functions: Create Function. You use a template to create the durable function code in your project.

When you've created the project, the Azure Functions Visual Studio Code extension automatically creates a virtual environment with your selected Python version. Install azure-functions-durable from PyPI It specifies the Python packages required to run your function app. This project contains the host.json and configuration files.Ī requirements.txt file is also created in the root folder. It also creates a function app project in a folder. Visual Studio Code installs the Azure Functions Core Tools if needed. Reopens Visual Studio Code in the folder you selected.
