find$\_$frequency$()$

This function should accept a single parameter named words. This parameter is expected to contain a list of strings representing words. The function should create a dictionary recording the number of times each individual word appears in words. Each dictionary key should be a string representing a word, and each value should be a count representing the number of times that string appeared in words.

Create an empty dictionary named freq$\_$dict to store the counts.

Loop over the elements of words. If a particular element has already been added to freq$\_$dict as a key then increment the value associated with that key. If the element does not appear as a key in freq$\_$dict, then add it as a key with a value of $1.$

The function should return the dictionary freq$\_$dict.

remove$\_$stop$()$

Stop words are words that are removed from a collection of words when performing a text analysis. These are typically very common words such as $"a"$ and "the".

This function should accept two parameters named words and stop. Both parameters are expected to contain a list of strings representing words. The function should return a list obtained by removing from words any strings that also appear in stop.

Create an empty list to store the non$-$stop words.

Loop over the elements of words. If a particular element does not appear in stop, then add it to the list create in Step $1.$ If the element does appear in stop, then do nothing.

The function should return the list of non$-$stop words.
