Syntax of if-else Statement
Let's briefly discuss the syntax of the if-else construct.
- The syntax of the
ifstatement remains unchanged;
if condition:
action
- Write the
elsekeyword. Note that it is case sensitive, so it is not the same as Else so if you use Else you will get an error because it is not correct;
if True condition:
action
else: # if False condition
other action
- Furthermore, you don't need to specify a condition when using
elsesince it inherently implies the opposite condition of the if part; - Simply use a colon;
- Then, proceed with code indentation for the instructions executed within the
else-block. These instructions are executed if our condition in theifstatement evaluates toFalse.
