    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!
