# Python Elif Statement

## Python elif

Python elif (short for else if) is used to execute a continuous chain of conditional logic ladder.

In elif, there are multiple conditions and the corresponding statement(s) as a ladder. Only one of the blocks gets executed when the corresponding boolean expression evaluates to true.

### Syntax of Python elif

The syntax of python elif statement is as shown below.

``````if boolean_expression_1:
statement(s)
elif boolean_expression_2:
statement(s)
elif boolean_expression_3:
statement(s)
else
statement(s)``````

You can have as many elif statements as required.

### Example 1: Python elif

Following is a simple Python elif demonstration. We take two numbers, and have a if-elif statement. We are checking two conditions, `a<b` and `a>b`. Which ever evaluates to True, when executed sequentially, the corresponding block is executed.

In the following program, `a<b` returns True, and therefore the if block is executed.

Python Program

``````a = 2
b = 4

if a<b:
print(a, 'is less than', b)
elif a>b:
print(a, 'is greater than', b)
else:
print(a, 'equals', b)``````
Run

Output

``2 is less than 4``

### Example 2: Python elif with multiple elif blocks

As we have already mentioned in the introduction, there can be multiple elif blocks. In the following example, we will write multiple elif blocks in the if-elif ladder.

Python Program

``````a = 2

if a<0:
print(a, 'is negative')
elif a==0:
print('its a 0')
elif a>0 and a<5:
print(a, 'is in (0,5)')
else:
print(a, 'equals or greater than 5')``````
Run

Output

``2 is in (0,5)``

For the given value of a, `a>0 and a<5` is the condition that evaluates to true in the if-elif ladder. Hence, the corresponding block gets executed.
