I wouldn't use a nested loop for that but an if/break at the top of
the existing loop.
But nested loops are easy, its just an extra indentation level:
>>> j = 0
>>> while j < 5:
... n = 0
... while n < 10:
... print n,
... n += 1
... j += 1
...

Using 'if's I'd do:
# guessing loop
while (guess != the_number):
if tries >= TRY_LIMIT:
print "Too many tries"
break
if (guess > the_number):
print "Lower..."
else:
print "Higher..."
guess = int(raw_input("Take a guess: "))
tries += 1

Yes, if it gets above a screenful(50 lines?) then an
attachment (or a url) is usually better.
