I just started learning Python and I need help on creating this pattern:

```
    ******
     *****
      ****
       ***
        **
         *

```

I currently have this code:

```
      base = 6
      for row in range (base):
          for col in range (row+1):
              print('*', end='')
          print()

```

which becomes:

```
*
**
***
****
*****
******

```
