В никакъв случай не добавяй коментар. Ако ти се наложи да коментираш код, написан на Python, в общия случай трябва просто да го пренапишеш.

Нужно е да се намери по-добро име и за двете. Мога да ти помогна с това, ако ми обясниш с по едно изречение какво прави всяка. :)

anagrams връща списък от списъци. При всяко викане anagrams_helper връща списък с думите, които са анаграми.

group_by_type_helper връща речник с всички елементи на първоначалния, които са от еднакъв тип. За първия пример >>> group_by_type({'a': 12, 'b': 1, 1: "foo"})

{<"class 'str'>: {'b': 1, 'a': 12}, <"class 'int'>: {1: 'foo'}} първото викане на group_by_type_helper ще върне речника {'b': 1, 'a': 12}, който отгаваря на типа str на ключовете, а второто ще върне {1: 'foo'}

И двете функции са написани с цел избягване от четворно влагане for -> if -> for -> if
