Python--使用fou循环用（ * ）打印空心的菱形

Python–使用fou循环用（ * ）打印空心的菱形

Python–使用fou循环用（ * ）打印空心的菱形：
例如：

layer = int(input("请输入要打印的层数："))
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="")

	# 再打印*
	star_num = 2*x - 1
	for y in range(0, star_num):
		if y == 0 or y == star_num - 1:
			print("*", end="")
		else:
			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="")

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