Alphabet Rangoli

    I threw in some math to reflect the structure of the diamond. Could probably consolidate parts of it, but I like how it shows where each part comes from.

    def print_rangoli(size):
    alphabet = "abcdefghijklmnopqrstuvwxyz"
    fill = "-"
    width = 2 * (size - 1)


    def build_line(index):
        l_text = "".join([alphabet[size - j - 1] + fill for j in range(index)]).rjust(
            width, fill
        )
        c_text = alphabet[size - index - 1]
        r_text = "".join([fill + alphabet[size - j] for j in range(index, 0, -1)]).ljust(
            width, fill
        )
        return l_text + c_text + r_text

    i = 0
    while i < 2 * size - 1:
        line_val = -abs(i - (size - 1)) + size - 1
        text = build_line(line_val)
        print(text)
        i += 1
