If Else Statement in Python

Hello friends how are you, today in this blog i will teach you what is if else statement, syntax of if else , how if else statement works and many programs using if else in a very simple way. 

Let's start

If else statement

Syntax:

if  condition  :
    body _of_if
else:
    body_of_else

• It is used to test the condition and gives the output in both situation either condition true or false.
• If the condition is true body of if will execute otherwise body of else execute.

Example 1:

no=int(input("Enter any number:"))
if no>5:
    print("Number is greater than 5")
else:
    print("Number is less than 5")
/*
Output
Enter any number:7
Number is greater than 5
*/

In the case of if at the place of condition always zero and non-zero value is checked in which zero means condition false and non-zero means condition true.

/*Example 1*/
if 10:
    print("Hello")
else:
    print("Hi")
/*
 ### Output ###
Hello
because 10 is non-zero value
*/
/*Example 2*/
if 0:
    print("Hello")
else:
    print("Hi")
/*
 ### Output ###
Hi
*/
/*Example 3*/
if 'A':
    print("Hello")
else:
    print("Hi")
/*
 ### Output ###
 Hello
 because ASCII value of A is 65
 which is non-zero
*/

Example 2: Check given number is even or odd.

no=int(input("Enter any number:"))
if no%2==0:
    print("Number is even")
else:
    print("Number is odd")
/*
Output
Enter any number:15
Number is odd
*/
