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

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. 

Simple steps just follow:

1. Open Notepad or Python IDLE shell.
2. Then type the below program in your notepad or Python IDLE shell.
3. Then save a file with proper file name along with .py extension 
4. Then compile the file with python file_name.py (in Command prompt) or In Python Shell press F5 to run the program.
5. 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.

Check the output 

Output 1 

Enter a number: 8

8 is Positive

Output 2

Enter a number: -7

-7 is Negative 

Output 3

Enter a number: 0

0 - Zero
