如果是奇数 ,就画属于这个奇数的菱形

while True:
    x = int(input("请输入数字判断奇数偶数"))
    if x & 1 == 0:
        print("请输入奇数")
    else:
        print(x, "是奇数")
        b = 1
        if x == x:
            a = x//2
            while x == x:
                print(" " * a + "*" * b)
                if x == 1:
                    break
                b += 2
                a -= 1
                if b == x:
                    break
            while x == x:
                print(" " * a + "*" * b)
                b -= 2
                a += 1
                if b < 1:
                    break
