IF … ELSE … STATEMENT

The if…else… statement lets your program choose between two options. Python checks the
condition; if it’s true, it executes statement block 1 after the if statement—otherwise, it executes
statement block 2 after the else statement. Start
Syntax of the if … else … statement:

if (condition):
Input Age
Statement block 1
else:
False
Statement block 2 Is Age>18?
Note that both statement blocks 1 and 2 are
indented. Block 1 is under if, so it will be executed True Print ‘Not Eligible’
if the condition mentioned is True. Block 2 is under Print ‘Eligible’

else, so it will be executed if the condition is False.
Here, if the age of the user is more than 18, ‘Eligible’
will be printed, otherwise ‘Not Eligible’ will be printed. Stop

Program 3 To show a message if the user is ‘Eligible’ or ‘Not Eligible’ to cast a vote.
