This is the most significant bit (MSB) of the byte (sometimes also called the sign bit ). The lower 7 bits are a payload; the resulting integer is built by appending together the 7-bit payloads of its constituent bytes.
2 Answers Sorted by: 26 The bitstring module is designed to address just this problem. It will let you read, modify and construct data using bits as the basic building blocks. The latest versions are for Python 2.6 or later (including Python 3) but version 1.0 supported Python 2.4 and 2.5 as well. WebThe following table describes the variable elements of a bit field − The variables defined with a predefined width are called bit fields. A bit field can hold more than a single bit; for example, if you need a variable to store a value from 0 to 7, then you can define a bit field with a width of 3 bits as follows −
