So I'm trying to make this program that will ask the user for input and store the values in an array / list. Then when a blank line is entered it will tell the user how many of those values are unique. I'm building this for real life reasons and not as a problem set. enter: happy enter: rofl enter: happy enter: mpg8 enter: Cpp enter: Cpp enter: There are 4 unique words! My code is as follows: # ask for input ipta = raw_input("Word: ") # create list uniquewords = [] counter = 0 uniquewords.append(ipta) a = 0 # loop thingy # while loop to ask for input and append in list while ipta: ipta = raw_input("Word: ") new_words.append(input1) counter = counter + 1 for p in uniquewords: ..and that's about all I've gotten so far. I'm not sure how to count the unique number of words in a list? If someone can post the solution so I can learn from it, or at least show me how it would be great, thanks! Continue reading...
