[issue19823] for-each on list aborts earlier than expected

[Matthew Barnett]

Matthew Barnett added the comment:

This issue is best posted to python-list and only posted here if it's agreed that it's a bug.

Anyway:

1. You have "self.flows" and "flows", but haven't said what they are.

2. It's recommended that you don't modify a collection while iterating over it, but, instead, build a new collection and then the old one with the new one.
