How to get unique instance id of azure function in python?

Question

I am trying to save some information (multiple rows) in database from Azure function (Python env.).

For this, I am looking for a unique identifier corr. to each run of azure function.

I have came across the word GUID at few places, but I cannot find any documentation on how to use this function or attribute in Azure Function Python environment.

Any help at earliest is appreciated.

GUID technology is not unique to Python Azure Function, it is a commonly used unique identifier which is generated based on the current time and computing machine, you can do this in python to generate it:

import uuid

print(uuid.uuid4())

In azure function, use below code to get it:

import logging

import azure.functions as func


def main(req: func.HttpRequest,context: func.Context) -> func.HttpResponse:
    logging.info(context.invocation_id)
    return func.HttpResponse(
            "This is the GUID:" + context.invocation_id,
            status_code=200
    )

Let me know whether this can help you.
