Here, we will learn to write a Python program through which we can check if the given number is positive, zero, or negative.

Positive Numbers: A number is said to be positive if the number has a value greater than 0, like 1, 2, 3, 5, 7, 9, 11, 13, etc. All the natural numbers are positive numbers.

Negative Numbers: If a given number has a value less than 0 like -1, -2, -3, -5, -7, -9, -11, -13, etc., then we can say that the given number is a negative number. Only rational and integer type numbers can have negative values or numbers.

# Default function to run if else condition  
def NumberCheck(a):   
    # Checking if the number is positive  
    if a > 0:   
        print("Number given by you is Positive")   
    # Checking if the number is negative   
    elif a < 0:   
        print("Number given by you is Negative")   
    # Else the number is zero  
    else:   
        print("Number given by you is zero")  
# Taking number from user  
a = float(input("Enter a number as input value: "))  
# Printing result  
NumberCheck(a)

Output:

Enter a number as input value: -6
Number given by you is Negative

Explanation:

We have used a nested if else condition in the program to check the number. When the user gives an input number, the program will first check if the value of the number is greater than 0 (if yes, it will print positive and the program ends), otherwise it will check if the value is less than 0 and it last it will print that number is 0.
