Check if Number is Positive or Negative Using Function

Level 1: Beginner

Dec 03, 2024

Project Level 2: Intermediate

This project is designed for intermediate learners who know Python fundamentals and are practicing building complete programs.

Project Description

In a previous project, we created a program that checked if a number was positive or negative, or zero:

number = float(input("Enter a number: "))

if number > 0:
  print("The number is positive.")
elif number < 0:
  print("The number is negative.")
else:
  print("The number is zero.")

In this project, your task is to improve that project by:

(1) Doing the checks inside a function definition and then calling that function.

(2) Including the number in the messages (e.g., “The number -5 is negative”) as shown in the Expected Output section.
