Simply collect all material in a string which you print to the screen. Then writing it to a file will be simple. To get both the word and its context you need an
indexed loop through the words. Use the stripw() function we saw on individual words to make finding hits more accurate (e.g. the program found 'river.' above). Finally, the join() method will come in handy to reconstruct the context as a string.</span><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'Times New Roman'; background-color: transparent; font-style: normal;"><span style="font-size: 16px;"><br></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'Times New Roman'; background-color: transparent; font-style: normal;"><span style="font-size: 16px;">Link to final product: </span><a href="http://imgur.com/q1aAAhp" style="font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; font-size: 12pt;">http://imgur.com/q1aAAhp</a></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'Times New Roman'; background-color: transparent; font-style:
