If Else and Else if and Nested If Statements in python programming language |Nested if program

Python If Else
It is likely that we will want the program to do something even when an if statement evaluates to false. In our grade example of previous tutorial, we will want output whether the grade is passing or failing.

Python If Else Syntax :

if condition:
statement
else:
statement


Python Nested If Else
for conditional statements, with each if statement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use an else if statement, which is written in Python as elif. The elif or else if statement looks like the if statement and will evaluate another condition. 

Python Nested If Else Syntax :

If condition :
statements
elif condition:
statements
else:
statements




Python Nested If Statement

We can use nested if statements for situations where we want to check for a secondary condition if the first condition executes as true. For this, we can have an if-else statement inside of another if-else statement. Let’s look at the syntax of a nested if statement:

if expression1:
statement(s)
if expression2:
statement(s)
elif expression3:
statement(s)
elif expression4:
statement(s)
else:
statement(s)
else:
statement(s)
