问题描述

您好,


我正试图找到一种方法来转换一个整数(8位长的

初学者)并将它们转换为一个清单,例如:


num = 255

numList = [1,1,1,1,1,1,1,1]


,列表中的第一个元素是最不重要的,所以

我可以继续附加到该列表而不必担心

整数的大小。我需要这样做,因为一些

函数调用可以返回2批32位数字。我必须找到一个

方式在列表中传输它...或者有更好的方法吗?

Hello,

I''m trying to find a way to convert an integer (8-bits long for
starters) and converting them to a list, e.g.:

num = 255
numList = [1,1,1,1,1,1,1,1]

with the first element of the list being the least significant, so
that i can keep appending to that list without having to worry about
the size of the integer. I need to do this because some of the
function call can return a 2 lots of 32-bit numbers. I have to find a
way to transport this in a list... or is there a better way?

推荐答案



num = 255

numlist = [num> i& 1我在范围内(8)]

num = 255
numlist = [num >i & 1 for i in range(8)]




num = 255

numlist = [num> i& 1 for i in range(8)]


num = 255
numlist = [num >i & 1 for i in range(8)]



谢谢matimus!我会调查一下......

numlist = lookup_table [num]


其中lookup_table是预先计算的列表列表。

numlist = lookup_table[num]

where lookup_table is a precomputed list of lists.
