process$\_$file$()$ This function should accept a single parameter named path. This parameter is expected to contain a string representing the relative location of a text file. The function will create and return a list of processed words contained in the file by performing the following tasks. $1.$ Use with and open$()$ to open the file whose location is stored in path. Use readlines$()$ to read the contents of the file into a list. Each string in this list will represent an entire line of text from the file. $2.$ Create an empty list named words. $3.$ Loop over the list created in Step $1.$ Apply the process$\_$line$()$ function to each string in this list. The list of words returned by process$\_$line$()$ should be concatenated to the end of the list words. The combined list should be stored back into words. Recall that you can concatenate two lists using the $+$ operator. The function should return the list words.
