Rookie problem. Problems in python3 while loop nesting print inverted triangle

1, print a triangle,
use while, to complete the output of the following graphics 

*
* *
* * *
* * * *
* * * * *
* * * *
* * *
* *
*

the code is as follows: 

h=1
while h<=5:
    w=1
    while w<=h:
        print("x",end="")
        w+=1
    print("")
    h+=1
h=5
while h>=1:
    w=5
    while w>=h:
        print("x",end="")
        w-=1
    print("")    
    h-=1
x
xx
xxx
xxxx
xxxxx
x
xx
xxx
xxxx
xxxxx

but the result I printed is like this, I really don"t understand how to reduce line 6 by one X in turn
ask the master to answer! Thank you!
