Python实现打印实心和空心菱形

a = int(input("请输入菱形每条边星星的个数："))
b = a
c = a
for i in range(1, a + 1):  # 先打印正三角，由空格和*根据规律组成
  print(" " * (b - 1), "*" * (2 * i - 1))
  b -= 1
  if i == a: # 临界点，当打印到此，开始打印倒三角
    for y in range(1, a):
      print(" " * y, "*" * (2*c-3))
      c -= 1

n = int(input("输入要打印的菱形的每个边的元素个数："))
list_a = [i for i in range(n)] # 生成前n行的行数列表，例如[0,1,2,3,4]
list_b = list_a[0:len(list_a) - 1:] # 生成剩余行数列表并反转，例如[0,1,2,3]
list_c = list_b[::-1]  # 对剩余行数列表并反转便于打印操作
list_d = list_a + list_c # 将两个列表合并

print(list_d)

b = [' ' * (n - i) + '*' * (2 * i + 1) for i in list_d]  # 根据规律，打印空格" "和"*"

for line in b:
  print(line)

a = int(input("请输入菱形每条边星星的个数："))
b = a
c = a
print(" " * (a - 1), "*")
for i in range(2, a+1): # 先打印正三角，由空格和*根据规律组成
  print(" " * (b - 1) + "*" + " " * (2 * i - 3) + "*")
  b -= 1
  if i == a: # 临界点，当打印到此，开始打印倒三角
    for y in range(2, a):
      print(" " * y+"*"+" "*(2*c-5)+ "*" )
      c -= 1
    print(" "*a+"*")
