Azure Functions

import azure.functions as func
import logging

app = func.FunctionApp()

@app.function_name(name="HttpTrigger")
@app.route(route="hello")
def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
            name = req_body.get('name')
        except ValueError:
            pass

    if name:
        return func.HttpResponse(f"Hello, {name}!")
    else:
        return func.HttpResponse(
            "Please pass a name",
            status_code=400
        )

@app.function_name(name="QueueTrigger")
@app.queue_trigger(arg_name="msg", queue_name="myqueue",
                   connection="AzureWebJobsStorage")
def queue_trigger(msg: func.QueueMessage):
    logging.info(f'Python queue trigger function processed: {msg.get_body().decode("utf-8")}')

Cosmos DB

from azure.cosmos import CosmosClient, PartitionKey

endpoint = "https://myaccount.documents.azure.com:443/"
key = "YOUR_KEY"

client = CosmosClient(endpoint, key)
database = client.create_database_if_not_exists(id="myDatabase")
container = database.create_container_if_not_exists(
    id="myContainer",
    partition_key=PartitionKey(path="/userId")
)

# Create item
item = {
    "id": "1",
    "userId": "user123",
    "name": "John Doe"
}
container.create_item(body=item)

# Query items
query = "SELECT * FROM c WHERE c.userId = @userId"
items = container.query_items(
    query=query,
    parameters=[{"name": "@userId", "value": "user123"}],
    enable_cross_partition_query=True
)

for item in items:
    print(item)
