process$\_$line$()$ This function should accept a single parameter named line. This parameter is expected to contain a string representing a line of text read from a file. The function should perform the following processing steps to the line: $1.$ Use the replace$()$ method to replace any dash characters $"-"$ with spaces, storing the result in a variable. $2.$ Apply the split$()$ method to the string created in Step $1$ to create a list of individual words contained within the string. Store the resulting list in a variable named words. $3.$ Loop over the elements of words. Apply the process$\_$word$()$ function to each string in this list. It is possible for the resulting processed word to be an empty string. If the processed word is not empty $($in other words, if it has a length greater than $0),$ then store it in a list named processed$\_$words.
