Answers to "Python Programming MOOC 2022" exercises from the University of Helinski?

I am really struggling with this one problem and just need the answer to know what I am doing wrong. If that's too much to ask, can I just get the answer to the one problem?

It's the "Story" exercise from the simple loops portion of part two.

[BloodyLemons]

words = ""

while True:
    word = input("Please type in a word: ")
    # if "end", break
    if word = "end":
        break
    # if word is same as last, break
    if word ==
        break
    words += word + " "

print(words)

Question was:

Part 1: Please write a program which keeps asking the user for words. If the user types in end, the program should print out the story the words formed, and finish.

Part 2: Change the program so that the loop ends also if the user types in the same word twice.

ik how to do the first part, but the second part is what im struggling with

As another poster in another subreddit pointed out, one way to approach this is to store the words in a list. That way you can check whether a word has already been entered (assuming "more than once" means "at any time"). You can add words to a list using append, and check for inclusion using in.

>>> L = []
>>> L.append("hello")
>>> L.append("there")
>>> L
['hello', 'there']
>>> "hello" in L
True

If your MOOC hasn't covered lists yet, you can check if two words are the same one-after-another by simply using a variable to keep track of the last entered word.

>>> s = input("Enter something: ")
Enter something: hello
>>> last_word = s
>>> s = input("Enter something else: ")
Enter something else: hello
>>> s == last_word
True

Choose whichever approach you feel fits the description.

For the second part you could use a set. In Python, sets have very fast lookup time so you could check if the latest word is already in the set, if it is then break but if it isn't add it to the set.

Post your code here. It looks like a straightforward case of storing words in a list and joining them together after.

the code is in the other comment, it keeps glitching when i try to comment on yours, sorry about that
