Python 3.5 string format: How to add a thousands-separator and also right justify?

How would I get a string that is equal to:

'    100,000.23'

Given that I have the variable

num = 100000.23

I can right justify with:

num = 100000.23
'{:>10.2f}'.format(num)

and I can thousands separate with:

num = 100000.23
'{:,}'.format(num)

But how can I do both at the same time?

Combine the two by adding a comma following the alignment instruction:

>>> '{:>12,.2f}'.format(num)
'  100,000.23'
