Python: How do I extract specific bits from a byte?
so are you asking how to represent a base 16 integer as base 2 in python, or are you asking how to extract certain bits of a number? or both, extract certain bits and display in binary? – jacoblaw. Commented Jul 20, 2017 at 17:07. What's the data type of that message?

BitManipulation - Python Wiki
bitLen() counts the actual bit length of a Python integer, that is, the number of the highest non-zero bit plus 1. Zero, with no non-zero bit, returns 0. As should be expected from the quote above about "the illusion of an infinite string of sign bits extending to the left," a negative number throws the computer into an infinite loop.

Solved: get bits from byte in Python - SourceTrail
3. Use bitwise AND: Finally, we apply the bitwise AND operator (&) between the shifted byte and the mask.This operation will extract only the desired bits, leaving the rest unchanged. Python’s Bitwise Operators and Libraries. Python’s bitwise operators play a significant role in extracting bits from bytes. These operators perform operations at the bit level, allowing us to manipulate ...

Extract Specific Bits of an Integer - Spiceworks Community
where thing is an unsigned int. A 32-bit unsigned integer (i.e. unsigned int thing) allows you to have 32 bit flags. So, it is really straightforward to deal with bit flags. First you setup your defines for the 8 bit flags (i.e. lower 8 bits): #define BIT_FLAG_1 0x00000001 #define BIT_FLAG_2 0x00000002 #define BIT_FLAG_3 0x00000004 #define BIT ...

Python Slicing | Extract ‘k’ bits from a given position
Finally, it converts the extracted bits to a binary string and then to an integer to get the decimal value. Algorithm. 1. Right shift the given number by p-1 bits to get the desired bits at the rightmost end of the number. 2. Mask the rightmost k bits to get rid of any additional bits on the left. 3. Convert the resulting bits to decimal using ...

I have a byte, I want to extract the bits (from MSB to LSB ... - Reddit
This is probably not quite what OP wants, since it sounds like the input is to be interpreted as a whole number of bytes, and .bit_length is the minimum number of bits required to represent the absolute value. That is to say, any leading zeroes in the MSB would be skipped. (Also, I think a nicer way to handle the bit operations is (input >> x) & 1.
