You need to implement __iter__ method to pass your assert statement:
def __iter__(self):
return reversed(self)
With regards to style guide:
1. write empty subclass
class rev_subclass(list):
pass
2. print dir(rev_subclass) and write unit tests for every method. There
are 41 of them :) There is also __doc__ attribute you need to override.
3. Implement all the methods of rev_subclass to pass the tests.
