I know printing primes isn't anything new, but (like always) I'd love to hear some feedback on how I can make my code more efficient and other constructive criticism.

```
def print_primes(r=10):
primes = [ ]
for i in range(2,r+1):
prime = 1
for divisor in range(2,i):
if i % divisor == 0:
prime = 0
break
if prime:
primes.append(i)
print "primes between 1 and %d:" % (r)
for prime in primes:
print prime,
print_primes()
```

Thanks.

EDIT: BAH! I CAN'T DELETE THIS! I just realized there's another prime thread and it has more advanced versions of this program. Sorry for the nuisance!
