Sort Array by Element Frequency doesn't work
Quest just does not work. https://py.checkio.org/mission/sort-array-by-element-frequency/solve/
My code: (it works properly) def frequency_sort(items: list) -> list: res = []
def ordered_set(items: list) -> list: """This function gets you list of unique ordered items from your origin list. It creates a copy""" resulting = items[::] # this way you can make a copy of list, not just a link popped = 0 # how many items we popped for i in range(len(resulting)): if i == 0: continue if resulting[i - popped] in items[0:i - popped]: popped += 1 pop_index = i - popped + 1 # index of an item script gonna pop out resulting.pop(pop_index) return resulting order_list = ordered_set(items) # here we assemble the resulting list by the order from ordered_set func for i in order_list: for j in range(len(items)): if items[j] == i: res.append(items[j]) return res
