ht[keyprint(vprint("the number of elements is{}format(ht count)notice that we also print the number of elements in the hash table this is useful for our next discussion non-string keys in most casesit makes more sense to just use strings for the keys howeverif necessaryyou could use any other python type if you create your own class that you want to use as keyyou will probably want to override the special __hash__(function for that classso that you get reliable hash values note that you would still have to calculate the modulo (%of the hash value and the size of the hash table to get the slot that calculation should happen in the hash table and not in the key classsince the table knows its own size (the key class should not know anything about the table that it belongs togrowing hash table in our examplethe hash table' size was set to obviouslyas we add elements to the listwe begin to fill up the empty slots at some pointall the slots will be filled up and the table will be full to avoid thiswe can grow the table when it is getting full to do thiswe compare the size and the count remember that size held the total number of slots and count the number of those slots that contained elementswellif count equals size then we have filled up the table the hash table' load factor gives us an indication of how large portion of the available slots are being used it is defined as follows
