Conditional Statements in Python
Syntax of if-else Statement
Let's briefly discuss the syntax of the if-else
construct.
- The syntax of the
if
statement remains unchanged;
- Write the
else
keyword. 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;
- Furthermore, you don't need to specify a condition when using
else
since 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 theif
statement evaluates toFalse
.
