bit manipulation - Python How to get set bit - Stack Overflow
To get the bit number of the highest bit set, you could use. int.bit_length()-1 This is much more efficient then using math.log() or the other function you had posted. EDIT: As requested, timeit results are posted: python -m timeit -s 'import math;x=100' 'int(math.log(x,2))' 1000000 loops, best of 3: 0.5 usec per loop

BitManipulation - Python Wiki
The number of the highest bit set is the highest power of 2 less than or equal to the input integer. This is the same as the exponent of the floating point representation of the integer, and is also called its "integer log base 2".(ref.1) In versions before 3.1, the easiest way to determine the highest bit set is*:

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 ...

Bitwise Operators in Python
Python’s int() treats all the bits as the magnitude, so there are no surprises there. However, this new function assumes a 32-bit long string by default, which means the sign bit is implicitly equal to zero for shorter strings. When you request a bit-length that matches your bit string, then you’ll get the expected result.

how to get the thighest bit position in big integers?
Hi, I'm using python to develop some proof-of-concept code for a cryptographic application. My code makes extended use of python's native bignum capabilities. In many cryptographic applications there is the need for a function 'get_highest_bit_num' that returns the position number of the highest set bit of a given integer.

sys.maxint in Python - GeeksforGeeks
In Python 2, sys.maxint refers to the maximum value an integer can hold on a given platform. This value is: 2³¹ - 1 = 2147483647 on a 32-bit system; 2⁶³ - 1 = 9223372036854775807 on a 64-bit system; sys.maxint was typically used as a very large number in algorithms requiring an upper bound, like finding minimum values in a list.. Note: sys.maxint has been removed in Python 3.
