You can use the sorted() function with a custom key that returns a tuple of the relevant keys.

Code Example:

Copy Code 


students = [
    {"name": "Alice", "age": 22, "gpa": 3.5},
    {"name": "Bob", "age": 20, "gpa": 3.8},
    {"name": "Charlie", "age": 21, "gpa": 3.7}
]

sorted_students = sorted(students, key=lambda x: (x["age"], -x["gpa"]))
print(sorted_students)

This sorts the list of students primarily by age in ascending order and secondarily by GPA in descending order.
