从python中的字节中提取LSB位

本文介绍了从python中的字节中提取LSB位的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在变量 DATA中有一个字节。我想从中提取LSB位并打印。 我是python的新手，我发现很多文章都具有复杂的按位加法逻辑，而所有这些都很难理解。 我正在寻找一个简单的逻辑，例如我们对字符串的处理，例如DATA [7：1] 请帮帮我...

I have a byte in variable 'DATA'. I want to extract the LSB bit out of it and print it. I'm very new to python, I found many articles with complex bitwise addition logic and all which was very tough to understand. I'm looking for a simple logic like we do with the strings eg DATA[7:1] Please help me out...

推荐答案

您的字节是 int 吗？如果是这样，只需将 1 ）与（（$code>& ）按位进行AND（或者，如果您想更明确一点，二进制文字 0b1 ）来获取最低有效位。

Is your "byte" an int? If so, just take bitwise AND (&) with 1 (or, if you want to be more explicit, the binary literal 0b1) to get the least significant bit.

>>> x = 14 >>> x & 1 0 >>> x = 15 >>> x & 1 1

您的字节是个字节对象？如果是这样，只需对其进行索引并进行按位与。

Is your "byte" a bytes object? If so, just index into it and take bitwise AND.

>>> y = bytes([14, 15]) >>> y[0] & 1 0 >>> y[1] & 1 1
