+It is also possible to iterate through the keys and items in the dictionary at the same time using the `items` function,
+which returns a *dict\_items* object containing `key, value` pairs:
+
+```python
+d.items()
+```
+
+```output
+dict_items([('alice', 35), ('bob', 18), ('jane', 24)])
+```
+
+This is very useful when using a dictionary in a `for` loop:
+
+```python
+for key, value in d.items():
+    print("Name:", key, " Age:", value)
+```
+
+```output
+Name: alice  Age: 35
+Name: bob  Age: 18
+Name: jane  Age: 24

 ## Presence (or not) of an element inside a dictionary
 
 It is possible to test if a key is present in the dictionary (or not) using the keyword `in`, just as we did at the start of this lesson for values within a list:
