 You then can use this to get **all** the results from a resource::
 
-  >>> iterator = MyIterator(...)
-  >>> list(iterator)  # Convert to a list (consumes all values).
+    >>> iterator = MyIterator(...)
+    >>> list(iterator)  # Convert to a list (consumes all values).
 
 Or you can walk your way through items and call off the search early if
 you find what you're looking for (resulting in possibly fewer
 requests)::
 
-  >>> for item in MyIterator(...):
-  >>>   print item.name
-  >>>   if not item.is_valid:
-  >>>     break
+    >>> for item in MyIterator(...):
+    >>>     print item.name
+    >>>     if not item.is_valid:
+    >>>         break
