From [1],
- _single_leading_underscore: weak "internal use" indicator. E.g. "from M
import *" does not import objects whose name starts with an underscore.
- __double_leading_underscore: when naming a class attribute, invokes name
mangling, i.e.
class SuperClass:
__boo # becomes _SuperClass__boo
class SubClass(SuperClass):
__boo # becomes _SubClass__boo # still a problem if SubClass === SuperClass
self._SuperClass__boo # NOT RECOMMENDED!
