Hướng dẫn how do you rotate an element in a list in python? - làm thế nào để bạn xoay một phần tử trong danh sách trong python?
|
Việc xoay vòng của một danh sách cũng đã được thảo luận trước đó, nhưng bài viết đặc biệt này tập trung vào các khoản viết tắt và các kỹ thuật ngắn khác nhau để đạt được điều này trong một lớp hoặc một từ. Hoạt động này khá cần thiết trong cuộc sống của một lập trình viên để đạt được các nhiệm vụ khác nhau. Hãy để thảo luận về các cách khác nhau, chúng ta có thể xoay một danh sách trong Python. & NBSP; Show
Phương pháp 1: Xoay danh sách bằng cách cắt lát & nbsp;Phương pháp cụ thể này là phương pháp chung và chủ yếu được sử dụng để đạt được nhiệm vụ này và cũng đã được thảo luận trong nhiều bài viết. Nó hoạt động bằng cách chỉ tham gia phần cắt sau này vào phần cắt lát ban đầu với số xoay. & NBSP; Python3Các Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]7 Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]8 Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]9 Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]0 Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]1 Original list : [1, 4, 6, 7, 2] List after left rotate by 3 : [7, 2, 1, 4, 6] List after right rotate by 3(back to original) : [1, 4, 6, 7, 2]2
