for loop with an integer in django's templates tags

In my Django template {{review.stars}} is an integer from 1 to 5, but instead of showing a simple number I want to show a number of star icons equal to the {{review.stars}} integer.

I should write something like:

for n in range(1, review.stars+1):  add star icon

but obviously I can't write something like that in Django template tags.What's the pythonic way to run a loop a variable number of times?
