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 the if statement evaluates to False.
