To do the conversion, you use a generator expression..partition(sep)The .partition(sep) call splits the target string at the first occurrence of string sep. The return value is a tuple with three objects:The portion of the target string that precedes sep The sep object itself The portion ...

The .__iter__() method is a generator function that returns an iterator. The resulting iterator yields the coordinates of ThreeDPoint on demand. The call to list() iterates over the attributes .x, .y, and .z, returning a list object. You don’t need to call .__iter__() directly...
