Python Workflows: How to implement a ForEach / Iterate edge for processing collections?

[cs609]

hi @eavanvalkenburg, @markwallace-microsoft
I'm looking for guidance on how to implement a foreach / iterate pattern in Python
workflows — i.e., iterating over each element in a collection and executing a sequence
of actions for every item.

Context

I've reviewed the Edges documentation
which covers:

• Conditional Edges — binary routing (if/else)
• Switch-Case Edges — multi-branch routing
• Multi-Selection Edges — fan-out to multiple targets
• Fan-in Edges — aggregation

However, there is no documented foreach / iterate edge pattern for Python workflows
that allows looping over a collection and running a sub-workflow per item.

1. What is the recommended pattern for implementing foreach in Python workflows today?
2. Is a built-in foreach edge type planned for the Python SDK ?
