You don't need to use lambda. The above line could have been done thisaway: >>> def f(x,y): return abs(x-y) >>> cl = HierarchicalClustering(data, f) So provided you can write a function to do what you want you don't need the lambda if it confuses you. In a general sense: def f(p): return expression is the same as f = lambda p: expression So anywhere that a function name is nmeeded you can put a lambda.
