If Else If Statement in Python

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

Let's start

If else if ladder statement

Syntax:

if  condition  :
    statement1
elif condition:
    statement2
elif condition:
    statement3
else:
    statement4

• It is used to test the condition.
• If executes only one condition at a time.
• The condition which is true first from the top will execute.

Example 1:

no=7
if no>10:  /*false*/
    print("Hello1")
elif no>5: /*true*/
    print("Hello2")
elif no>0: /*true*/
    print("Hello3")
else:
    print("Helllo4")
/*
 ### Output ###
 Hello2
 because it executes only one condition 
 which becomes true first from top.
 */

else part will execute if all the conditions are false

no=-5
if no>10:
    print("Hello1")
elif no>5:
    print("Hello2")
elif no>0: 
    print("Hello3")
else:
    print("Helllo4")
/*
 ### Output ###
 Helllo4
 because  all conditions are false.
*/

Example 2:Show result according to percent

percent=float(input("Enter your percentage:"))
if percent>=60:
    print("First division")
elif percent>=45:
    print("Second division")
elif percent>=33:
    print("Third division")
else:
    print("Sorry!!! You are fail.")
/*
Output
Enter your percentage:56
Second division
*/

Example 3:Find greatest value in three number

#taking user input for numbers
no1=int(input("Enter first number:"))
no2=int(input("Enter second number:"))
no3=int(input("Enter third number:"))
#applying condition on numbers
if no1>no2 and no1>no3:
    print(no1," is greatest value")
elif no2>no1 and no2>no3:
    print(no2," is greatest value")
else:
    print(no3," is greatest value")
"""
###Output###
Enter first number:78
Enter second number:85
Enter third number:54
85  is greatest value
"""
