You are going to create some mad libs. there are two files available: a word list full of common words ("words. txt"), and a short story ("story. txt"). process both files line-by-line in order to replace the words from the first file in the short story with the string "" (four underscores). then, print the resulting story, each line of the story on its own line. one issue you may encounter: you cannot loop through a file again after you have read its contents once. solve this issue by storing the words file in a list before processing the story. you may find it to keep in mind the mutability of certain types. you may also find it to refer to the replace documentation.
