Python Slicing | Extract ‘k’ bits from a given position

How to extract ‘k’ bits from a given position ‘p’ in a number? Examples: Input : number = 171 k = 5 p = 2 Output : The extracted number is 21 171 is represented as 10101011 in binary, so, you should get only 10101 i.e. 21.Input : number = 72 k = 5 p = 1 Output : The extracted number is 8 72 is represented as 1001000 in binary, so, you should get only 01000 i.e 8.

BitManipulation - Python Wiki

Prior to Python 3.1, there was no easy way to determine how Python represented a specific integer internally, i.e. how many bits were used. Python 3.1 adds a bit_length() method to the int type that does exactly that.

Mathematically get $n$th bit from integer

Otherwise bit0 is (1+(-1^(value+1)))/2 - applicable for any integer value or any function that returns integer value. Attempts to emulate mod of a function may lead to result which also contain mod operation. To get n-th bit, first lets shift value/function: shift right is

python - Extracting bits from bytes - Stack Overflow

I am handling compressed data. The format contains a lookup table, and an array of long ints, which each may contain multiple values. Bit length of contained values varies depending on the file. I have access to these longs as bytes: is there an easy way to access a particular bit / bit range, or do I have to make one from scratch ?
