+# Exercise 1:
+# Advantages of methods over free functions:
+# 1- Methods keep related data and behavior together
+
+# 2- Methods make code easier to read (person.is_adult() is clearer than is_adult(person))
+
+# 3- Methods reduce the number of parameters (because self already contains the data)
+
+# 4- Methods help mypy catch more errors (because they belong to a specific class)
+
+# 5- Methods make the code more object‑oriented and easier to extend
