-Subject: [PATCH 2/2] Convert to python3
|
|
|
-
|
|
|
-Python 2.7 will not be maintained past 2020. Let's convert
|
|
|
-to python3 for rcw. Below were the changes of this patch.
|
|
|
-- Adapted print usage
|
|
|
-- Didn't use tab anymore
|
|
|
-- Handled str and bytes type separately
|
|
|
-- Other minor changes
