    Really enjoyed solving it! Great to see so many different solutions here but sad at the same time im unable to understand most rn.. 😅

    def print_rangoli(size):
    alphabets = [chr(i) for i in range(97,97+size)]
    width = size + (size-1)*3
    lines = []
    for i in range(0,size):
        line = str(alphabets[i])
        for j in range(i+1,len(alphabets)):
            line = alphabets[j] + "-" + line
            line += "-" + alphabets[j]   
        lines.insert(0,line.center(width,"-"))
        if i != 0:
            lines.append(line.center(width,"-"))
        
    for i in lines:
        print(i,end="\n")
