Danh sách () trong Python là gì?

Danh sách Python giống như các mảng có kích thước động, được khai báo bằng các ngôn ngữ khác (vector trong C++ và ArrayList trong Java). Nói một cách đơn giản, danh sách là một tập hợp các thứ, được đặt trong [ ] và được phân tách bằng dấu phẩy.  

Danh sách là một kiểu dữ liệu trình tự được sử dụng để lưu trữ bộ sưu tập dữ liệu. Tuples và String là các kiểu dữ liệu chuỗi khác

Danh sách là các thùng chứa đơn giản nhất là một phần không thể thiếu của ngôn ngữ Python. Các danh sách không cần phải luôn đồng nhất, điều này khiến nó trở thành công cụ mạnh nhất trong Python. Một danh sách có thể chứa các Kiểu dữ liệu như Số nguyên, Chuỗi, cũng như Đối tượng. Danh sách có thể thay đổi và do đó, chúng có thể được thay đổi ngay cả sau khi tạo

Tạo một danh sách trong Python

Danh sách trong Python có thể được tạo bằng cách đặt chuỗi bên trong dấu ngoặc vuông[]. Không giống như Bộ, danh sách không cần chức năng tích hợp để tạo danh sách.  

Ghi chú. Không giống như Bộ, danh sách có thể chứa các phần tử có thể thay đổi.

Thêm phần tử vào danh sách Python

Phương pháp 1. Sử dụng phương thức append()

Các phần tử có thể được thêm vào Danh sách bằng cách sử dụng hàm append() tích hợp sẵn. Mỗi lần chỉ có thể thêm một phần tử vào danh sách bằng cách sử dụng phương thức append(), để thêm nhiều phần tử bằng phương thức append(), các vòng lặp được sử dụng. Các bộ dữ liệu cũng có thể được thêm vào danh sách bằng cách sử dụng phương thức append vì các bộ dữ liệu là bất biến. Không giống như Bộ, Danh sách cũng có thể được thêm vào danh sách hiện có bằng cách sử dụng phương thức append()

Sự phức tạp khi thêm các phần tử trong một Lists(append() method)

Phương pháp 2. Sử dụng phương thức chèn()

Phương thức append() chỉ có tác dụng khi thêm phần tử vào cuối List, để thêm phần tử vào vị trí mong muốn thì sử dụng phương thức insert(). Không giống như append() chỉ nhận một đối số, phương thức insert() yêu cầu hai đối số (vị trí, giá trị).

Có thể xóa các phần tử khỏi Danh sách bằng cách sử dụng hàm remove() tích hợp nhưng Lỗi sẽ phát sinh nếu phần tử không tồn tại trong danh sách. Phương thức Remove() chỉ xóa một phần tử tại một thời điểm, để xóa một loạt phần tử, trình vòng lặp được sử dụng. Phương thức remove() xóa mục đã chỉ định

Ghi chú. Phương thức xóa trong Danh sách sẽ chỉ xóa lần xuất hiện đầu tiên của phần tử được tìm kiếm

Cắt một danh sách

Chúng ta có thể lấy các chuỗi con và danh sách con bằng cách sử dụng một lát cắt. Trong Danh sách Python, có nhiều cách để in toàn bộ danh sách với tất cả các phần tử, nhưng để in một dải phần tử cụ thể từ danh sách, chúng ta sử dụng thao tác Slice.  

Thao tác lát cắt được thực hiện trên Danh sách bằng cách sử dụng dấu hai chấm (. ).  

Để in các phần tử từ đầu đến một phạm vi, hãy sử dụng

[. Mục lục]

Để in các phần tử từ mục đích sử dụng cuối

[. -Mục lục]

Để in các phần tử từ một Chỉ mục cụ thể cho đến khi sử dụng hết

[Mục lục. ]

Để in toàn bộ danh sách theo thứ tự ngược lại, hãy sử dụng

[. -1]

Lưu ý – Để in các thành phần của Danh sách từ phía sau, hãy sử dụng Chỉ mục phủ định.
