Similarly, there are plenty of cases where a nameless function is MUCH
clearer than breaking it out into a separate def and then using the
name once. Do you name the function for what it does internally?
def get_oneth_element_index(item):
return item[1].index
L.sort(key=get_oneth_element_index)
Or for how you're using it?
def keyfunc(item):
return item[1].index
L.sort(key=keyfunc)
Or do you just shortcut the whole thing by inlining it?
L.sort(key=lambda item:item[1].index)
I still prefer the "def" variant. It even allows you to clarify the
meaning of the tuple slot by using a nicer name.
Each to their own. Here give me the lambda version any day of the week.
