The exercise frequency sort 'extra' test solutions work on my computer but not on checkio.
The checkio 'extra' tests change from day to day??? Because of this problem I can't finish the mission and see additional solution.

From: https://py.checkio.org/mission/sort-array-by-element-frequency/solve/

This is my code for the frequency sort: def frequencysort(items): listcountfrequency = [] listinterated = [] countfrequency = [] myziptuple = () sortedtuplerev =() unzippedreversedtuple = [] unzippedrvsedtupleindex = [] free = True #

create two lists: 1 - a list of the frequency of each itter

2 - a list of the itters

## if list_count only includes one then return same string


for i in items:
    count_frequency = items.count(i)
    list_count_frequency.append(count_frequency)
    list_interated.append(i)

 #if there is only one occurance of each i in list
 # finds out if all the counts are the same in the list all()
if set(list_count_frequency) == {1}:
    return items

 ## if items is empty return empty     
if items == []:
    return items
print(list_count_frequency)
print(list_interated)

zip up the two lists into a tuple

my_zip_tuple = list(zip(list_interated, list_count_frequency ))
print(my_zip_tuple)

#free = all(x == listcountfrequency[0] for x in listcountfrequency) if all(x == listcountfrequency[0] for x in listcountfrequency)== False: print('help')

#sort the tuple in reverse  
    sorted_tuple_rev =sorted(my_zip_tuple, key=lambda x: (x[1], x[0]), reverse = True)            
    print(sorted_tuple_rev)
# take reversed tuple and  unzip it
    unzipped_reversed_tuple = list(zip(*sorted_tuple_rev))
    print(unzipped_reversed_tuple)
#get first list in unzipped tuple
    unzipped_rvsed_tuple_index = unzipped_reversed_tuple[0]
    print(unzipped_rvsed_tuple_index)

    return unzipped_rvsed_tuple_index
