It's hard to see from your post what the problem is, but an if-else is formatted like so

 if someCondition:
     do_something       # could be a single statement, or a series of statements
 else:
     do_something_else  # could be a single statement, or a series of statements

I.e., the else needs to be at the same level as the corresponding if.

See this Python doc/tutorial on if, and this other tutorial too.

Sometimes when your editor does autoindent for you and you edit manually too things might get messed up, so you'll have to figure out how your editor handles indentations (e.g., is it always using tabs or spaces?, what happens if you hit return etc).

Also, be wary of mixing tabs and spaces, that will cause problems too (hard to spot since both are "invisible")

With your updated post:

   if xyzzy.endswith('l'):
       print xyzzy
   else:
       something_else
