In this simple Python program, we have to check the entered number or value is positive, negative, or zero. For that, we have to know the number is greater than zero or less than zero;
Here, we make familiar with "
if condition ",
elif statement" and "else statement". For a better understanding of these conditional statements in python we always recommend you to learn the basic topics of Python programming listed below:
In this basic python program, we need to check the number is greater than or less than zero or the number is zero itself. So in the Python program, we accept the input from the user using the input function and convert that string to an integer using a
int() function also, save that input into a variable. Then use the
if-elif-else conditional statements in python for checking the number is greater than or less than zero. Let's break the code step by step.
STEP 1: Accept the number from the user using the
input() function. In python, accept values in string format only so we have to use an
int() to convert that string to an integer.
STEP 2: We use
if conditional statement to check if the number is less than zero, and if that condition is satisfied, then we have to print that the given value is negative.
STEP 3: Use statement
elif [which is similar to else if statement in C language] to check if the number is greater than zero. And if that condition is true, then print its positive.
STEP 4: Use
else statement to print the given number is zero.
number = int(input("Enter the number: ")) if number < 0: print("The entered value is negative.") elif number > 0: print("The entered value is positive.") elif number == 0: print("The entered value is zero.") else: print("Invalid input")
Enter the number : 2 The entered value is positive.
