Cho một danh sách các số, hãy viết chương trình Python để xóa nhiều phần tử khỏi danh sách dựa trên điều kiện đã cho
Ví dụ.
Input: [12, 15, 3, 10] Output: Remove = [12, 3], New_List = [15, 10] Input: [11, 5, 17, 18, 23, 50] Output: Remove = [1:5], New_list = [11, 50]
Có thể xóa nhiều phần tử khỏi danh sách trong Python, dựa trên kiến thức chúng tôi có về dữ liệu. Giống như, chúng tôi chỉ biết các giá trị sẽ bị xóa hoặc cũng biết chỉ mục của các giá trị đó. Hãy xem các ví dụ khác nhau dựa trên các tình huống khác nhau
Ví dụ 1. Giả sử chúng ta muốn xóa từng phần tử trong danh sách chia hết cho 2 hoặc tất cả các số chẵn.

Ví dụ #2. Sử dụng hiểu danh sách
Loại bỏ tất cả các phần tử chẵn trong danh sách cũng tốt như chỉ bao gồm tất cả các phần tử không chẵn [ i. e. phần tử lẻ].
