Trong ví dụ này, tôi sẽ chỉ cho bạn python lấy n phần tử cuối cùng của danh sách. Hướng dẫn này sẽ cung cấp cho bạn một ví dụ đơn giản về cách lấy n phần tử cuối cùng của danh sách trong python. hãy thảo luận về danh sách python lấy n phần tử cuối cùng. Ở đây bạn sẽ học cách lấy n phần tử cuối cùng của danh sách python
Chúng ta có thể sử dụng [-N. ] để lấy n phần tử cuối cùng của danh sách python. Trong ví dụ này, chúng tôi sẽ lấy biến myList với số lượng danh sách. Sau đó, chúng ta sẽ thêm n biến để lấy n số mục cuối cùng trong danh sách python. hãy xem các ví dụ

Làm cách nào để lấy giá trị cuối cùng từ từ điển trong Python?
Chúng ta sẽ lấy giá trị cuối cùng từ từ điển python sử dụng các hàm keys[] và values[] .
Làm cách nào tôi có thể trích xuất tất cả các giá trị từ một từ điển trong Python?
Phương pháp #1. Sử dụng vòng lặp + phím[]
. Đây có thể là một trong những phương pháp để thực hiện nhiệm vụ này.
