To do the urls, you could use something like this
[i + j for i, j in zip(list_of_urls, string.ascii_lowercase[:14])]
Assuming this is a homework ;-) - no need to summon libraries etc - it probably expect you to use range() with chr/ord, like so:
for i in range(ord('a'), ord('n')+1): print chr(i),
For the rest, just play a bit more with the range()
Hints:
import stringprint string.ascii_lowercase
and
for i in xrange(0, 10, 2): print i
"hello{0}, world!".format('z')
