Question

Runtime stack python not showing on Azure Portal

Simon 25

Hi everyone!
I am trying to create an Azure Function App and I am not being able to select python as my Runtime stack. It simply isn't showing on the dropdown menu. I have seen it showing before. runtime_stack_no_python

Hi Simon,

I'm running into the same issue with an Azure Function Consumption plan. It looks like it's an intermittent UI issue. If you look just below your screenshot you might see the Operating System is locked in as Windows-only (where Python requires Linux). For me I waited a few minutes, logged out/in, and the OS option showed up again for me.

Hi @Simon,

If Python is not appearing as an option in the Runtime stack dropdown menu while setting up an Azure Function App, there may be several reasons for this:

Python applications are only supported on Linux within Azure Functions. If you are attempting to create a function app on Windows, Python will not be listed as an option.
Make sure you are using a hosting plan that supports Python. Python applications can only be created on Linux with either a Premium plan or a Dedicated (App Service) plan. If you are on a Consumption plan, Python will not be an available option.
Sometimes, temporary issues with the Azure portal can cause certain options to not display correctly. Refreshing the page or trying again later might resolve the issue.

For more details, refer to the documentations:

I hope this helps resolve your issue. Feel free to reach out if you have further concerns.
