the biggest leap in productivity i've experienced is after i tried parinfer (https://shaunlebron.github.io/parinfer/). seriously, just find the plugin for your editor, it is amazing, the cognitive load of balancing is simply gone.
I believe failing to recommend parinfer to a newbie doesn't make sense in any case, as it binds a very common issue for newcomers (the parentheses management) with something that is very intuitive, indentation with meaning, which in my opinion is part of the huge success of python.
I've also seen at least 4 people in the chats/forums that had errors because of parinfer. So no, I won't recommend it to a beginner.
In my experience, as my IDE (Intellij Idea) highlights lines that are changes for git, these errors are trivially detected. But perhaps for a newbie, this could be confusing? In any case I still think it is a net win.
