What is the difference between prefixing attributes and methods with a double underscore and single underscore?
|

|

#### --distractors--
|

|
||||
#### --answer--

Placeholder answer
|
||||
Single underscore is just a convention for internal use, double underscore triggers name mangling to prevent accidental attribute and method overriding.
