Please use python and dont use counters. Just simple python functions. Also if you can show how to do least frequent. Thanks

def most common key (d: dict) ->list: Given d representing the number of occurrences of each key within the data set analyzed, give a list of the keys that occur the most frequently Note: there could be multiple keys that occur most frequently, which is why we're returning a list. If there is only one most frequent key, the returned value would just be a list of one element that is that key
