编写程序，输入顶行字符和图形的高，(输入的顶行字符与高从键盘上直接输入，如A 7)输出下图所示图形。 A B B C C D D E E D D C C B B A

topChar = input("请输入顶行字符：")
height = int(input("请输入图形的高："))

for i in range(height):
    line = " " * (height-i-1) # 每行前面的空格
    if i == 0 or i == height-1:
        line += topChar + " " * (2*i)
    else:
        line += topChar + " " * (2*i-1) + topChar
    print(line)
    
for i in range(height-2, -1, -1):
    line = " " * (height-i-1) # 每行前面的空格
    if i == 0 or i == height-1:
        line += topChar + " " * (2*i)
    else:
        line += topChar + " " * (2*i-1) + topChar
    print(line)

运行结果：

请输入顶行字符：A
