The if…elif…else Ladder
The if…elif…else ladder is another type of if statement. It helps us to test multiple conditions and
follows a top-down approach. In this, as soon as the condition of the if evaluates to be true, the indented
block associated with that ‘if’ is executed, and the rest of the ladder is avoided. If none of the conditions
evaluates to true, then the final else statement gets executed.
The syntax of if...elif...else ladder is shown below:
Syntax:
if (Test Expressions_1):
Indented block 1
elif (Test Expression_2):
Indented block 2
