Question

Write a structured (procedural) Python program that solves the following spec:

Soundex System Coding: Soundex is a system that encodes a word into a letter followed by three numbers that roughly describe how the word sounds. Therefore, similar sounding words have the same four-character code. Use the following set of (slightly modified #4) rules to create a translator from English words to Soundex Code:

1. Retain the first letter of the word.
2. For letters 2 …n, delete any/all occurrences of the vowels (a,e,I,o,u), h, w, y.
3. Assign the following numbers to any remaining letters in the word
   1. 1 for occurrences of b, f, p, v.
   2. 2 for occurrences of c, g, j, k, q, s, x, z
   3. 3 for occurrences of d, t
   4. 4 for L
   5. 5 for M, N
   6. 6 for R
4. For repeated numbers, remove the repeats (“PROGRAMMING” à P6265552 à P62652)
5. Keep only the first four characters of what you have left (P62652 à P626) However, if you have less than 4 characters, 0 fill the empty spots so that ALL words have 4-character soundex codes. (e.g. “Anita” à A53 à A530)

Python program Requirements: Your program is expected to…

1. Well-documented (name, date, description at the top; good naming conventions)
2. provide a description and instructions for the user.
3. ask for the player’s name and encode it for them, then use their Soundex code name to refer to them.
4. Ask them to encode as many names/words as they would like to until they enter 0 to quit.
5. have a minimum of 4 subprograms (including a main() ).
6. store the entered names/words with their codes into a dictionary (name/word as key). When they are finished, present them with a sorted list of the name/words and their soundex codes neatly formatted.

Soundex is primarily used as a tool to group homophobic English-sounding surnames. It was developed by Robert C. Russell and Margaret King over 100 years ago!

Answer 1

thanks for the question, here is the python code with screenshot. I ran for two words PRORAMMING and ANITA and its giving the right soundex code.

let me know for any questions, comments added for each important function

# function accepts a raw word

    word = word.upper()
    delete_letters = ['A', 'E', 'I', 'O', 'U', 'H', 'W', 'Y']
    modified = word[0]
    for letter in word[1:]:
        if letter not in delete_letters:
            modified += letter
    return modified

    previous = 0 # track the previous letter
    modified = word[0] # keep the first letter
    # iterate over each letter in the word
    for i in range(1, len(word)):
        if i == 1:

            modified += str(letter_keys.get(word[i]))
        else:

            if number != previous:

                previous = number
    if len(modified) >= 4:
        return modified[:4]
    else: # append extra 0 at the end
        spaces = 4 - len(modified)
        return modified + '0' * spaces


# main function that accepts a raw word and retursn the soundex code of the word
def convert_to_soundex(word):
    word = delete_vowels(word)
    return assign_number(word)


def main():

    while True:
        word = input('Enter a word/name to convert (enter 0 to quit): ').upper()
      if word == '0': break
        print(convert_to_soundex(word))


main()
