Python functions on Azure Functions 2.X (Public Preview)

This is a collection of Python function samples on Azure Functions 2.X. For a comprehensive development and debugging experience, use the Azure Functions Core Tools or VS Code extension.

Samples

Sample	Description	Trigger	In Bindings	Out Bindings
cosmosdb-trigger-cosmosdb-in-binding	Azure Functions Blob Storage Trigger Python Sample. The function gets image data from Azure Blob Trigger, gets tags for the image with Computer Vision API (Azure Cognitive Services), and store the tags into Azure Cosmos DB by leveraging Cosmos DB output binding	Blob Storage	NONE	CosmosDB
cosmos-trigger-cosmodb-output-binding	Azure Functions Cosmos DB Trigger Python Sample. The function gets document data from Azure Cosmos DB Trigger, ROT13 encodes obtained clear text, and store encoded data into Azure Cosmos DB by using Cosmos DB output binding	CosmosDB	NONE	CosmosDB
queue-trigger-blob-in-out-binding	Azure Functions Queue Trigger Python Sample. The function gets a file name from queue message, reads a blob file named the file name using Blob Input Binding, then ROT13 encodes the obtained clear text, and finally stores it into Azure Blob Storage using Blob Output Binding	Queue Storage	Blob Storage	Blob Storage
timer-trigger-cosmos-output-binding	Azure Functions Timer Trigger Python Sample. The function gets blog RSS feed and store the results into CosmosDB using Cosmos DB output binding	Timer	NONE	CosmosDB
http-trigger-blob-sas-token	Azure Function HTTP Trigger Python Sample that returns a SAS token for Azure Storage for the specified container and blob name	HTTP	NONE	HTTP
http-trigger-dump-request	Azure Function HTTP Trigger Python Sample that returns request dump info with JSON format	HTTP	NONE	HTTP
http-trigger-onnx-model	This function demonstrates running an inference using an ONNX model. It is triggered by an HTTP request.	HTTP	NONE	HTTP
blob-trigger-watermark-blob-out-binding	Azure Function Python Sample that watermarks an image. This function triggers on an input blob (image) and adds a watermark by calling into the Pillow library. The resulting composite image is then written back to blob storage using a blob output binding.	Blob Storage	Blob Storage	Blob Storage
sbqueue-trigger-sbqueue-out-binding	Azure Functions Service Bus Queue Trigger Python Sample. The function demonstrates reading from a Service Bus queue and placing a message into an output Service Bus queue.	Service Bus Queue	None	Service Bus Queue

Python functions on Azure Functions 1.X (Experimental)

IMPORTANT

• By default, function apps created in the Azure portal are set to version 2.x. When possible, you should use this runtime version, where new feature investments are being made. Please see this for more detail on Azure Function runtime versions and supported languages.
• Please consider to use 2.X Python funciton as Python function in Azure function 1.X is experimental and new feature investments won't be added to 1.X Python function.

Sample	Description	Trigger	In Bindings	Out Bindings
