使用 * 输出直角三角形

height = int(input("please input height: "))

tmp = 1
while tmp <= height:
    width = tmp
    while width > 0:
        print("*", end="")
        width -= 1
    print("")
    tmp += 1

height = int(input("please input height: "))

while height > 0:
    tmp = height
    while tmp > 0:
        print("*",end="")
        tmp -= 1
    print()
    height -= 1
