Python Elif
Python Elif is a conditional statement in which there could be multiple conditional checks after if block.
Python elif is an extension to Python if-else statement.
Syntax of Python elif
Following is the syntax of Python Else If, elif statement.
if expression_1:
statement(s)
elif expression_2:
statement(s)
elif expression_3:
statement(s)
else:
statement(s) If expression_1 evaluates to TRUE, then the if block statements gets executed and the control comes out of the if-elif ladder.
If expression_1 evaluates to FALSE, the control checks expression_2. If expression_2 evaluates to TRUE, statement(s) in the corresponding block are executed. If expression_2 evaluates to false, the control checks expression_3 and so on.
If none of the expressions evaluates to TRUE, then the else block gets executed. else block is optional though.
Example 1 – Python Elif Statement
In the following example, we will write a Python elif statement, where we check what is today and do an action based on the day of week.
example.py – Python Program
today='Monday'
if today=='Sunday':
print('Do nothing.')
elif today=='Monday' or today=='Tuesday':
print('Clean the floor.')
elif today=='Wednesday':
print('Prepare chicken.')
elif today=='Thursday':
print('Visit Library.')
else:
print('Go for excercise.') Try Online Output
Clean the floor.
Example 2 – Python Elif Statement without else block
We already know that else block is optional.
In the following example, we will write a Python elif statement without else block.
example.py – Python Program
today='Monday'
if today=='Sunday':
print('Do nothing.')
elif today=='Monday' or today=='Tuesday':
print('Clean the floor.')
elif today=='Wednesday':
print('Prepare chicken.')
elif today=='Thursday':
print('Visit Library.') Try Online Output
Clean the floor.
Conclusion
In this Python Tutorial, we learned Python elif statement: the syntax of elif and how to use it in Python programs with the help of example programs.
