The term "dunder" means "double underscore". This will be on both sides of the names of "magic" methods such as __init__. You also need a space between the keyword "def" and the method name.

So instead of "def_init" :point_right: "def __init__"
and instead of "super().__init_" :point_right: "super().__init__"
and instead of "iter" :point_right: "__iter__"

And check your indentation. You won't want to define one magic method inside another one.
