在python中用for或者while打印这个图形怎么弄，求帮助

Question

不会在for循环中套用while循环
首先我的思路是分为上下两部分进行
目前最主要的问题是，并不知道上部分的右边对称怎么弄出来

Write a program to print a diamond made up of left-and right-aligned right-angled isosceles triangles, all of positive integer height specified by the user's keyboard input (a positive integer), as follows:

Enter triangle height: 6
************
*****  *****
****    ****
***      ***
**        **
*          *
**        **
***      ***
****    ****
*****  *****
************

Answer 1

图没发出来啊
for循环中套用while循环
for i in range(1,n):
while(true):
xxxx
上半部分

a = int(input())
b = a
c = a
for i in range(6):
    for j in range(6-i):
        print('*',end='')
    for j in range(2*i):
        print(' ',end='')

    for j in range(6-i):
        print('*',end='')
    print()
