How does python perform bitwise operations to store three values in an int?

bit bitwise-operators integer python python-3.x

For example, if I have an int with a length of 32 bits, how do I store value A in the first 16 bits, then store value B in bits 17-24, and value C in bits 25-32? And how can I get these three values out of an int? Answer Assuming that your values fit in the assigned bit counts,

Bit Manipulation, find another shortest array whose binarian is same as the given array’s binarian

algorithm bit python

Given an array A, its binarian(A) is defined as 2^A[0] + 2^A[1] + …. 2^A[n]; Questions asks to find anther shortest array B whose binarian(B) is same as A’s. For example, A=[1,0,2,0,0,2]，thus if B=[3,2,0], this satisfies the requirements, and the output is 3. Could you guys provide some ideas of how to solve this problem? Thanks. Answer Here’s a solution

Using Python How can I read the bits in a byte?

bit byte python

I have a file where the first byte contains encoded information. In Matlab I can read the byte bit by bit with var = fread(file, 8, ‘ubit1’), and then retrieve each bit by var(1), var(2), etc. Is there any equivalent bit reader in python? Answer Read the bits from a file, low bits first.
