reload(sys)
sys.setdefaultencoding("utf-8")


def forwardTriangle():
    for i in range(0, row):
        for k in range(0, i + 1):
            print ("*"),
        print("\n")


def reversedTriangle():
    for i in range(0, row):
        for k in range(0, row - i):
            print ("*"),
        print("\n")


if __name__ == '__main__':
    row = input("请输入一个数字:")
    forwardTriangle()
    print ("--------")
    reversedTriangle()
