In this tutorial you will learn about the Python Program to Check if a Number is Positive, Negative or 0 and its application with practical example.
In this tutorial, we will learn to create a Python Program to Check if a Number is Positive, Negative or Zero(0) using python Programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following Python programming topics:
- Python Operator.
- Basic Input and Output
- Basic Python programming.
- Python if-else statements.
- Python Loop.
What is Positive Numbers ?
A number is called to be a positive number if it has a value Bigger than 0 (number >0), for example ‘1,2,3,4,5,6,7,8,9,10,11,12,13,..’,etc. All are Positive number and also natural numbers.
What is Negative Numbers ?
A number is called to be a Negative number if it has a value smaller than 0 (number < 0), for example ‘-1,-2,-3,-4,-5,-6,-7,-8,-9,-10,-11,-12,-13,..’etc .All are Negative number and also natural numbers.
Python Program to Check if a Number is Positive, Negative or 0
In our program below we will check given number is Positive ,Negative or Zero number .First we would declared and initialized the required variables. Next, we would prompt user to input a number .Later we will find entered value is positive ,negative or Zero.

1 2 3 4 5 6 7 8 9 10 11 12 13 |
# creating a pyhton program to fing given number is postive ,negative or Zero #taking value from user. number = float(input("Enter any number: ")) #checking condiotn for positive if number > 0: print("It is a Positive number") #checking condtion for Zero elif number == 0: print("Number is Zero") #checking condtion for Negative else: print("It is a Negative number") |
Output
Inputted Number is Positive Number
Negative Number
Inputted Number is Zero.
In our program, we have first declared and initialized a set variables required in the program.
- number =taking year value from user.
First of all we declare variable and take a value from user to check whether a entered number is positive ,negative or Zero.
After taking values from user we will check that if a number is greater than zero (number>0)then the given number is Positive .
Now we will check that if a number is smaller than zero (number<0)then the given number is Negative .
Here, we going to use if…elif…else statement.Now at last if the given number is equal to Zero than the given number is zero.
