Python 3 program to check if a number is positive, negative or 0

We can easily do it using Python elif loop where we can check three conditions to see if the number entered by the user is positive or negative.

Condition 1: If the user input is greater than 0, then the number is positive.

Condition 2: If the user input is less than 0, then the number is negative.

Condition 3: If the other two conditions are false, then the number is zero.

Source Code:

num = float(input("enter any number: "))

if num > 0:
    print("+ve number")

elif num < 0:
    print("-ve number")

else:
    print("Zero")
