Python program to check if a given number is Positive or Negative or Zero

Now i am going to explain how to find a number is positive or negative or zero using python programming. Here i am going to apply if condition to check the number. if the number greater than 0 it is positive number. Less than 0 - negative number number =0- it is a zero.

Requirements

Must install Python on your computer system.

Notepad++

Command prompt (CMD).

or

You can use Python IDLE to type and run the program.

Open Notepad or Python IDLE shell.
Then type the below program in your notepad or Python IDLE shell.
Then save a file with proper file name along with .py extension
Then compile the file with python file_name.py (in Command prompt) or In Python Shell press F5 to run the program.
All done

Program code (Python) Method-1

num = int(input("Enter a number: "))

if num > 0:

print(num,"is Positive number")

elif num == 0:

print(num,"- Zero")

else:

print(num,"is Negative number")

Program code (Python) Method-2

// nested if to find //

num = int(input("Enter a number: "))

if num >= 0:

if num == 0:

print(num,"- Zero")

else:

print(num,"is Positive number")

else:

print(num, "is Negative number")

Clear Definition

Here 'num'- is a variable to store the value.

input() is a function to get input.

if , elif, else are the conditional checking the condition true or not.

print() is a function to display the value.
