Modify the sentence$-$generator program of Case Study $5-1($in the file generator.py$)$ so that it inputs its vocabulary from a set of text files at startup. The filenames are nouns.txt$,$ verbs.txt$,$ articles.txt$,$ and prepositions.txt$.($Hint: Define a single new function, getWords. This function should expect a filename as an argument. The function should open an input file with this name, define a temporary list, read words from the file, and add them to the list. The function should then convert the list to a tuple and return this tuple. Call the function with an actual filename to initialize each of the four variables for the vocabulary.$)($LO: $5\mathrm{.}1,5\mathrm{.}2)$

Please modify the program below:
