I am wondering if the question was answered?
x = [[1,2],[3,4],[5,6]] import ast ast.dump(ast.parse('[x for x in x for x in x]'))

This is really, I think, the answer to the OPs question. Knowing how python is parsing the comprehension of comprehensions is important, yes?
Obviously each x is within a different scope, within a separate iterator. This seems to unwind from right to left?
I didn't see any ast entries in the thread, so just wondering. marcus -- https://mail.python.org/mailman/listinfo/python-list
