Check if Number is Positive or Negative Using Function

Level: Beginner

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.

Expected Output

Learning Benefits

• Conditional Statements: Practice using if-elif-else statements to make decisions based on conditions.

• Input and Output: Practice taking user input and displaying output to the console.

• Comparison Operators: Utilize comparison operators like >, <, and == to compare numbers.
