You can now
develop functions using Python 3.13 locally and deploy them to Azure Functions.
Starting with
Python 3.13, Functions introduces runtime version control, a new opt-in
feature that lets you target specific versions of the Functions Python runtime
used by your app. Python 3.13 also introduces several enhancements to Functions
that improve performance and reliability. In
Python 3.13+, Azure Functions no longer supports custom worker extensions
and shared memory for large payloads, requiring migration to supported
alternatives and gRPC-based messaging. For more detail, check out the full documentation:

and guidance for Python 3.13+ in Azure Functions.
