The document provides an overview of decision-making statements and loops in Python, including 'if', 'if...else', 'if...elif...else', and nested if statements. It also explains loops, detailing the 'for' and 'while' loops, along with examples and flowcharts for better understanding. Each section includes programmatic examples illustrating how to use these constructs effectively.

16. WHAT ARE LOOPS?
•Loops are the set of
instruction which allows
us to execute a statement
or group of statements
multiple times.
