Problem type
Canadian Computing Competition: 2002 Stage 1, Junior #2

Americans spell differently from Canadians. Americans write neighbor and color while Canadians write neighbour and colour. Write a program to help Americans translate to Canadian.

Your program should interact with the user in the following way. The user should type a word (not to exceed 64 letters) and if the word appears to use American spelling, the program should echo the Canadian spelling for the same word. If the word does not appear to use American spelling, it should be output without change. When the user types quit! the program should terminate.

The rules for detecting American spelling are quite naive: If the word has more than four letters and has a suffix consisting of a consonant followed by or, you may assume it is an American spelling, and that the equivalent Canadian spelling replaces the or by our. Note: you should treat the letter y as a vowel.

    Hello Do you guys know why my code does not work?

    put = ''
    lis = []
    while put != 'quit!':
        put = input()
        if len(put) >= 4 and put[-2:] == 'or':
            put = put[:-2] + 'our'
        elif len(put) > 0 and put != 'quit!': 
    [print(item) for item in lis]

    [print(item) for item in lis] is the end of code

      you have to ensure the letter before 'or' is a consonant

    For anyone struggling there's something that (I believe) is not clearly stated which is that for the rule to apply (change "or" to "our") the "or" must be at the END of the sentence

    I feel like my solution is correct (output looks right) but the judge doesn't like my answer, even when it solves the suggested output...

    Someone care to chime in and help me out? Thanks!

    word = input()
    vowels = list('aeiouy')
    while word != 'quit!':
      if len(word) > 4:
        for i in range(1, len(word)):
          if (word[i] == 'r') and (word[i-1] == 'o') and (word[i-2] not in vowels):
            word = word[:i]+'u'+ word[i:]
      word = input()

      I thought y wasn't a vowel... edit: nevermind I just read that it said to treat y as a vowel

      Make sure that "or" must appear at the middle of the word (i.e suffix). Currently your program replaces "or" with "our" even if "or" appears somewhere else like in the middle, but it must appear at the end

    I had mine first try, but was printing 'quit!' along side my output

    don't do that! I was very confused.

    instructor -> instructour (I'm not English native and based on my knowledge it doesn't exist 'instructour' word) but my answer is still accepted. If anyone can explain it that would be great. Thanks

      Instructour is not actually a word.

      "The rules for detecting American spelling are quite naïve:"

      The program does not actually detect if words are real words. After all, you could potentially have a word 64 letters long. It is just detecting a sequence, and making the changes. So in this instance, correct answers are not necessarily real words. I hope that make sense for you.

      Now if you see this, try and answer my question below please :D

    Be careful, vowel+or still no need to change, like floor...

    For those that know American vs Canadian spellings, neighbor should become neighbour, but instructor should not become instructour. But according to the given rules, it should. Given the spelling/structure of those words, I'm not sure how to tell the program how to tell the difference.

      I think you're too tripped over how American spelling really is. Pretend that this is the new way of American spelling; since it's a 3 pointer, they're not looking for anything complicated.

    Can I assume the input is all lowercase letters?

      it wont happen, according to the ccc test cases, but i believe the problem statement is clear enough
