From f58bdd01487af85f669abcb15d3b0dc72b6b976c Mon Sep 17 00:00:00 2001 From: Adam Williamson Date: Tue, 2 Jun 2020 13:22:17 -0700 Subject: [PATCH] Fix and standardize ElementTree imports for Python 3.9 Importing `cElementTree` has been deprecated since Python 3.3 - importing `ElementTree` automatically uses the fastest implementation available - and is finally removed in Python 3.9. Importing cElementTree directly (not as part of xml) is an even older relic, it's for Ye Time Before ElementTree Was Added To Python and it was instead an external module...which was before Python 2.5. So let's just standardize on importing ElementTree from xml.etree. Also, let's not repeat this import 12 times in one file for some reason.
