Is there a way to abuse assignment expressions or functional tools to generate the sequence x, f(x), f(f(x)), ... in one line? Here are some contrived examples to demonstrate: def iter(x, f, lim=10): for _ in range(lim): yield x x = f(x) iter(1, lambda x: (2*x)%99) "One-argument accumulate" is even uglier. The idea is to use the binary function but ignore the list elements! from itertools import accumulate list(accumulate([None]*10, lambda x,y:2*x, initial=1)) Continue reading...
