 Descriptor Protocol
 -------------------
 
-``descr.__get__(self, obj, type=None) --> value``
+``descr.__get__(self, obj, type=None) -> value``
 
-``descr.__set__(self, obj, value) --> None``
+``descr.__set__(self, obj, value) -> None``
 
-``descr.__delete__(self, obj) --> None``
+``descr.__delete__(self, obj) -> None``
