Python would like a word...
I know what _underscoring does in Python and what PEP8 recommends but doing it all the time for everything is so ugly and unnecessary.
Making variables and methods private means making them inaccessible outside the class and I gave the typical reasons/best practices for that.
The point they are making is in python there's no private method, everything is public. There's only a convention of "avoid using anything starting with "_"
