  • DunderMethods

  • Module level definition of dunder methods dir() and attr():

    I was facing this issue of hinding actual imports of my module with user. It was always confusing when someone calls "dir()" on my modules. There is already dunder method called "dir()" to override this behaviour, but this method was limited to Classes. With this version, it is possible to override the behaviour of module by defining module level __dir__() method.

    TODO: Write the example of them here.

  • attr : You can override this method for various purposes like firing an API deprication warning. The method will behave just as it was behaving on Class.

    TODO: Example of attr at module level.
