#菱形的打印
layer = int(input("请输入需要打印的层数："))
for x in range(1,  layer + 1):
	#先打印空格
	space_num = layer - x
	for y in range(0, space_num):
		print(" ", end="")

	#在打印*
	star_num = 2*x - 1
	for y in range(0, star_num):
		print("*", end="")
	#换行
	print("")

for x in range(layer - 1, 0, -1):
	#先打印空格
	space_num = layer - x
	for y in range(0, space_num):
		print(" ", end="")

	#在打印*
	star_num = 2*x - 1
	for y in range(0, star_num):
