An awkward thing about programming in Python: there are lots of double underscores. For example, the standard method names beneath the syntactic sugar have names like __getattr__, constructors are __init__, built-in operators can be overloaded with __add__, and so on. [...]Thus, __proto__ is pronounced “dunder proto”.
My problem with the double underscore is that it's hard to say. How do you pronounce __init__? “underscore underscore init underscore underscore”? “under under init under under”? Just plain “init” seems to leave out something important.
I have a solution: double underscore should be pronounced “dunder”. So __init__ is “dunder init dunder”, or just “dunder init”.
