I'm not sure what you mean by the first half of your comment. Both def and lambda create functions, and quoting from the article "Lambda expressions are just a special syntax for making functions. They can only have one statement in them and they return the result of that statement automatically.".
def binds it to a name at the same time, which is remembered in the object (which AFAIK isn't really used for anything except maybe debugging tools), lambda returns an anonymous one. The resulting object can be passed around in both cases.
