I currently have a long list which is being sorted using a lambda function f. I then choose a random element from the first five elements. Something like: f = lambda x: some_function_of(x, local_variable) my_list.sort(key=f) foo = choice(my_list[:4]) This is a bottleneck in my program, according to the profiler.
