Question

Python

The Python "<" and ">" comparison operators can be used to compare which string variable has a greater value based on comparing the ASCII codes of the characters in each string, one by one. To take some examples: "tets" > "test" returns True because the third letter of the first string, "t", has a greater value than the third letter of the second string, "s". "testa" > "test" returns True because—while the first four letters in both words are letter-for-letter the same—the first word has a fifth letter, "a", while the second word does not. Also "test" > "test" returns False because both words have the same ASCII values in the same order. One limitation of the Python comparison operators (“<" and ">") is that they only return True or False values. But this does not indicate the ordinal position of the letter (first or second or third or fourth, and so on) that decides which word has a greater value. To allow for a string comparison result that is informative regarding the ordinal position of the deciding letter, define a function called highest_value_word (word1, word2, ordinal_position=1). This function takes three parameters: word1 is a string, word2 is a string, and ordinal_position is an integer. The function returns an integer value that indicates both which word has the highest value and also the ordinal position of the character that decides this result. The magnitude of the integer that is returned by highest_value_word() is the ordinal position of the character that decided which word has the greater value. Additionally, this returned integer value is negative if word1 has a higher value than word2 or else is positive if word2 is greater than word1. If both word1 and word2 are the same, the function returns zero. Your function should compare the ASCII values of letters of word1 and word2 that are in the ordinal position specified by the ordinal_position parameter (1 = first; 2 = second; 3 = third, and so on). The default value of ordinal_position is 1. If the letters in that ordinal position are the same, then the function must recursively call highest_value_word() with the ordinal_position parameter incremented by 1. Example 1: if word1 was "weka" and word2 was “kiwi", then the function would return -1, because a comparison of the ASCII codes of the characters in the first ordinal position shows that "w" in word1, "w", is greater than "k" in word2, "k". The negative sign indicates that word1 has the higher value. Example 2: if word1 was "tree" and word2 was “trees", then the function would return 5, as a comparison of the characters in the fifth ordinal position of each word decides that word2 has a greater value (as word2 has a fifth character, while wordt does not). The positive value of the result indicates that word2 has the higher value. (See further examples below.) Note 1: You can use the inbuilt Python ord() function to return the ASCII value of a string character. Note 2: You must use recursion to answer this question (i.e., not loops).

RAW CODE

def highest_value_word(word1,word2,ordinal_position=1):
    if word1 == word2:
        return 0
    elif word1 == '':
        return ordinal_position
    elif word2 == '':
        return ordinal_position
    elif word1[0] == word2[0]:
        ordinal_position += 1
        found  = highest_value_word(word1[1:],word2[1:],ordinal_position)
        if found:
            return found
        print(ordinal_position)
    elif word1[0] > word2[0]:
        return ordinal_position * -1
    else:
        return ordinal_position

if __name__ == '__main__':
    word_list = ["Kiwi","Weka"]
    print(highest_value_word(word_list[0],word_list[1]))
    word_list = ["Ruru","Ruru"]
    print(highest_value_word(word_list[0],word_list[1]))
    word_list = ["Kaka","Kakapo"]
    print(highest_value_word(word_list[0],word_list[1]))
    word_list = ["Huia","Hoiho"]
    print(highest_value_word(word_list[0],word_list[1]))

Answer 2

Words like first, second and third are referred to as ordinal numbers. In this exercise, you will write a function that takes an integer as its only parameter and returns a string containing the appropriate English ordinal number as its only result. Your function must handle the integers between 1 and 12 (inclusive). It should return an empty string if the function is called with an argument outside of this range. Include a main program that demonstrates your function by displaying each integer from 1 to 12 and its ordinal number. Your main program should only run when your file has not been imported into another program.
