Iterating on the powers of 2 below N would be done by :
for i in Range(1, N, lambda x:x*2)
I haven't seen this discussed before, but I may not have searched enough.
Any opinions ?
I'm surprised no one mentioned this!?
for i in map(lambda x:2**x, range(1, 10)): ... print(i) ... 2 4 8 16 32 64 128 256 512
It looks like map returns a map object which is a generator. You just need to use the power of 2 formula rather than accumulate it. That's actually more flexible solution as your range can start some place other than 1.
for i in map(lambda x:2**x, range(5, 10)): ... print(i) ... 32 64 128 256 512
