Python | Power of Two | Programming Tutorials

Introduction

In computer science, it is often necessary to determine if a given number is a power of two. This can be useful in a variety of applications, such as optimizing algorithms or checking for errors in data transmission. In this challenge, we will write a Python function to determine if a number is a power of two.

Power Two

Problem

Write a Python function called is_power_of_two that takes in an integer as its parameter and returns True if the input is a power of two, and False otherwise. A power of two is any number that can be expressed as 2^n, where n is an integer. For example, 2, 4, 8, and 16 are all powers of two.

Requirements

The is_power_of_two function must meet the following requirements:

The input number must be an integer.
The function must handle invalid inputs gracefully.
The output must be a boolean.
The function must fit within memory constraints.

Example Usage

Here are some examples of how the is_power_of_two function should behave:

is_power_of_two(None) should raise a TypeError.
is_power_of_two(0) should return False.
is_power_of_two(1) should return True.
is_power_of_two(2) should return True.
is_power_of_two(15) should return False.
is_power_of_two(16) should return True.

Summary

In this challenge, we wrote a Python function to determine if a given number is a power of two. We learned that a power of two is any number that can be expressed as 2^n, where n is an integer. We also learned how to handle invalid inputs and ensure that our function meets memory constraints.
