Question

4. Design an n-out-of-m code that could represent the letters A-Z plus a space character and the usual punctuation symbols (. ,;:? !). 5. Design an n-out-of-m code that could code nearly the entire 128-character ASCII set. What advantage(s) would this code have over the usual 7-bit binary code? What makes your code better than other possible n-out-of-m codes? 6. Explain why a three-out-of-five code is essentially the same as a two- out-of-five code. In general, why is an n-out-of-m code equivalent to ar (m- n)-out-of-m code?

Explanation / Answer

def main():

    string = ' !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~'

    char_count = 0

    white_space_count = 0

    ascii_count = 0

    non_ascii_count = 0

    non_ascii_chars = []

    text = input('Enter a text to analyze: ')

    for ch in text:

        char_count += 1

        if ch.isspace():

            white_space_count += 1

        if ch in string:

            ascii_count += 1

        else:

            non_ascii_chars.append(ch)

            non_ascii_count += 1

    print()

    print('Total number of characters: ' + str(char_count))

    print('Total number of white spaces: ' + str(white_space_count))

    print('Total number of ASCII characters: ' + str(ascii_count))

    print('Total number of non-ASCII characters: ' + str(non_ascii_count))

    print('The non-ASCII letters were: ', end='')

    for i, ch in enumerate(non_ascii_chars):

        print(ch, end='')

        if i != len(non_ascii_chars) - 1:

            print(", ", end='')

    print()

if __name__ == '__main__':

    main()
