    Used string cropping for this one

    def print_rangoli(size):
    letters = [x for x in range(1, size + 1)]
    string = [chr(ord('a') + n - 1) for n in letters]

    if (size == 1):
        print("".join(string))
        return

    string_reversed = "-".join(string)
    string = reversed(string)
    string = "-".join(string)
    
    size *= 2
    
    for x in range(1, size, 2):
        print(f"{string[:x]:->{size - 1}}-{string_reversed[(size - x + 1):]:-<{size - 3}}")
        
    
    for x in reversed(range(1, size - 1, 2)):
        print(f"{string[:x]:->{size - 1}}-{string_reversed[(size - x + 1):]:-<{size - 3}}")

    used the logic of tiagozr to create the list of strigs with characters.

    Added my logic to print (it's easier):

    def print_rangoli(size):
    n = size
    letter = 96 + n
    max_len = 4*n-3
    strings = []

    for i in range(n):
        s = []
        for j in range(letter, letter-i-1, -1):
            s.append(chr(j))
        for k in range(letter-i+1, letter+1):
            s.append(chr(k))
        strings.append("-".join(s))

    for string in strings:
        print(string.center(max_len, '-'))
    strings.reverse()
    for string in strings[1:]:
        print(string.center(max_len, '-'))


if __name__ == '__main__':
    n = int(input())
    print_rangoli(n)
