for row in range(row_len):
    nb_whitespaces = col_len//2 - row  # calculate number of whitespaces that should be prints at first of each row
    nb_asterisk = row+1                # calculate how many Asterisk that should be prints for each row
    print(nb_whitespaces * " " + "* " * nb_asterisk)
