Bit Manipulation Fundamentals | Python Programming

Introduction

Bit manipulation is a fundamental concept in computer science and is widely used in various fields. It involves manipulating individual bits that make up a binary number. In Python, we can perform common bit manipulation operations such as getting a bit, setting a bit, clearing a bit, and updating a bit. In this challenge, we will implement these operations.

Bit Manipulation Operations

Problem

Implement the following common bit manipulation operations in Python:

get_bit: Given a number and an index, return the value of the bit at the given index.
set_bit: Given a number and an index, set the value of the bit at the given index to 1.
clear_bit: Given a number and an index, set the value of the bit at the given index to 0.
clear_bits_msb_to_index: Given a number and an index, set all bits from the most significant bit to the given index to 0.
clear_bits_index_to_lsb: Given a number and an index, set all bits from the given index to the least significant bit to 0.
update_bit: Given a number, an index, and a value, update the value of the bit at the given index to the given value.

Requirements

The implementation should meet the following requirements:

The inputs may not be valid, and the implementation should handle such cases gracefully.
The implementation should fit memory.

Example Usage

Here are some examples of how to use the implemented functions:

get_bit:

number   = 0b10001110
index = 3
expected = True

set_bit:

number   = 0b10001110
index = 4
expected = 0b10011110

clear_bit:

number   = 0b10001110
index = 3
expected = 0b10000110

clear_bits_msb_to_index:

number   = 0b10001110
index = 3
expected = 0b00000110

clear_bits_index_to_lsb:

number   = 0b10001110
index = 3
expected = 0b10000000

update_bit:

number   = 0b10001110
index = 3
value = 1
expected = 0b10001110

number   = 0b10001110
index = 3
value = 0
expected = 0b10000110

number   = 0b10001110
index = 0
value = 1
expected = 0b10001111

Summary

In this challenge, we implemented common bit manipulation operations in Python. These operations are essential in various fields, including computer science, cryptography, and networking. By mastering these operations, we can efficiently manipulate binary data and perform complex computations.
