Determine Number Within Range in Python

Introduction

In Python, we can check if a given number falls within a specified range using arithmetic comparison. This is a common task in programming and can be useful in many different applications.

Number in Range

Problem

Write a function in_range(n, start, end = 0) that takes in three parameters:

n: a number to check if it falls within the range
start: the start of the range
end: the end of the range (optional, default value is 0)

The function should return True if the given number n falls within the specified range, and False otherwise. If the end parameter is not specified, the range is considered to be from 0 to start.

Example

in_range(3, 2, 5) ## True
in_range(3, 4) ## True
in_range(2, 3, 5) ## False
in_range(3, 2) ## False

Summary

In this challenge, you learned how to check if a given number falls within a specified range using arithmetic comparison in Python. This is a useful skill that can be applied in many different programming applications.
