+# When we try to print sum_value and product_value, they will both be None because the functions don’t return values.
+# Key Differences:
+# With return: The function returns the result, which can be stored and reused. You have more flexibility to use the values.
+# With print: The function directly prints the result, but you cannot store or reuse the value in the calling code. Any attempt to store the result will lead to None.
