The if…elif statement

The if…elif statement in Python is used when you need to choose between more than two alternatives. The elif clause can be used to create a number of conditions that can be evaluated. The syntax of the statement is:

if condition:
	statements
elif condition:
	statements
elif condition:
	statements
.
.
.
else:
	statements

Consider the following example:

print('Available cars: ')
print('1.BMW')
print('2.Ford')
print('3.Tesla')
print('4.Chrysler')
print('5.Toyota')

x = int(input('Select your car: '))

if x == 1:
    print('You have selected BMW.')
elif x == 2:
    print('You have selected Ford.')
elif x == 3:
    print('You have selected Tesla.')
elif x == 4:
    print('You have selected Chrysler.')
elif x == 5:
    print('You have selected Toyota.')
else:
    print ('Invalid selection.')

Here is the output:

Available cars: 
1.BMW
2.Ford
3.Tesla
4.Chrysler
5.Toyota
Select your car: 2
You have selected Ford.

The example above begins by displaying a menu. A user is prompted to make a selection by entering a number between 1 and 5. The user’s selection is then evaluated. If the user enters anything other then these numbers, the Invalid selection message will be displayed.
