+Sorting a list of dictionaries in Python can seem intimidating at first. This is especially true if you want to **sort using multiple keys**. Luckily, the `sorted()` function can be used to sort a list of dictionaries using a tuple `key`. Simply return a **tuple** with the order of keys you want to sort by and the `sorted()` function will do the rest.

+```py
+friends =  [
+  {"name": "John", "surname": "Doe", "age": 26},
+  {"name": "Jane", "surname": "Doe", "age": 28},
+  {"name": "Adam", "surname": "Smith", "age": 30},
+  {"name": "Michael", "surname": "Jones", "age": 28}
+]
+
+print(
+  sorted(
+    friends,
+    key=lambda friend:
+    (friend["age"], friend["surname"], friend["name"])
+  )
+)
+# PRINTS:
+# [
+#   {'name': 'John', 'surname': 'Doe', 'age': 26},
+#   {'name': 'Jane', 'surname': 'Doe', 'age': 28},
+#   {'name': 'Michael', 'surname': 'Jones', 'age': 28},
+#   {'name': 'Adam', 'surname': 'Smith', 'age': 30}
+# ]
+```
