Danh sách nào sau đây là hợp lệ trong python
Cấu trúc dữ liệu cơ bản nhất trong Python là dãy. Mỗi phần tử của một chuỗi được gán một số - vị trí hoặc chỉ mục của nó. Chỉ số đầu tiên bằng 0, chỉ số thứ hai là một, v.v. Show
Python có sáu loại trình tự tích hợp sẵn, nhưng những loại phổ biến nhất là danh sách và bộ dữ liệu, mà chúng ta sẽ thấy trong hướng dẫn này Có một số điều bạn có thể làm với tất cả các loại trình tự. Các hoạt động này bao gồm lập chỉ mục, cắt, thêm, nhân và kiểm tra tư cách thành viên. Ngoài ra, Python có các hàm tích hợp để tìm độ dài của một chuỗi và tìm các phần tử lớn nhất và nhỏ nhất của nó Danh sách PythonDanh sách này là kiểu dữ liệu linh hoạt nhất có sẵn trong Python, có thể được viết dưới dạng danh sách các giá trị (mục) được phân tách bằng dấu phẩy giữa các dấu ngoặc vuông. Điều quan trọng về danh sách là các mục trong danh sách không nhất thiết phải cùng loại Tạo danh sách đơn giản như đặt các giá trị được phân tách bằng dấu phẩy khác nhau giữa các dấu ngoặc vuông. Ví dụ - list1 = ['physics', 'chemistry', 1997, 2000]; list2 = [1, 2, 3, 4, 5 ]; list3 = ["a", "b", "c", "d"]; Tương tự như chỉ mục chuỗi, chỉ mục danh sách bắt đầu từ 0 và danh sách có thể được cắt, nối, v.v. Truy cập các giá trị trong danh sáchĐể truy cập các giá trị trong danh sách, hãy sử dụng dấu ngoặc vuông để cắt cùng với chỉ mục hoặc các chỉ mục để lấy giá trị có sẵn tại chỉ mục đó. Ví dụ - #!/usr/bin/python3 list1 = ['physics', 'chemistry', 1997, 2000] list2 = [1, 2, 3, 4, 5, 6, 7 ] print ("list1[0]: ", list1[0]) print ("list2[1:5]: ", list2[1:5]) Khi đoạn mã trên được thực thi, nó tạo ra kết quả sau - list1[0]: physics list2[1:5]: [2, 3, 4, 5] Cập nhật danh sáchBạn có thể cập nhật một hoặc nhiều phần tử của danh sách bằng cách đưa lát cắt ở phía bên trái của toán tử gán và bạn có thể thêm vào các phần tử trong danh sách bằng phương thức append(). Ví dụ - #!/usr/bin/python3 list = ['physics', 'chemistry', 1997, 2000] print ("Value available at index 2 : ", list[2]) list[2] = 2001 print ("New value available at index 2 : ", list[2]) Lưu ý - Phương thức append() được thảo luận trong phần tiếp theo Khi đoạn mã trên được thực thi, nó tạo ra kết quả sau - Value available at index 2 : 1997 New value available at index 2 : 2001 Xóa phần tử danh sáchĐể xóa một phần tử danh sách, bạn có thể sử dụng câu lệnh del nếu bạn biết chính xác (những) phần tử nào bạn đang xóa. Bạn có thể sử dụng phương thức remove() nếu không biết chính xác mục nào cần xóa. Ví dụ - #!/usr/bin/python3 list = ['physics', 'chemistry', 1997, 2000] print (list) del list[2] print ("After deleting value at index 2 : ", list) Khi đoạn mã trên được thực thi, nó tạo ra kết quả sau - ['physics', 'chemistry', 1997, 2000] After deleting value at index 2 : ['physics', 'chemistry', 2000] Lưu ý - phương thức remove() được thảo luận trong phần tiếp theo Hoạt động danh sách cơ bảnCác danh sách phản hồi các toán tử + và * giống như các chuỗi; Trên thực tế, các danh sách đáp ứng tất cả các thao tác trình tự chung mà chúng ta đã sử dụng trên các chuỗi trong chương trước 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.

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 PythonDanh 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.

Ô(1) Cắt một danh sáchChúng 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
Để in các phần tử từ mục đích sử dụng cuối
Để in các phần tử từ một Chỉ mục cụ thể cho đến khi sử dụng hết
Để in toàn bộ danh sách theo thứ tự ngược lại, hãy sử dụng
Lưu ý – Để in các thành phần của Danh sách từ phía sau, hãy sử dụng Chỉ mục phủ định. TÌM HIỂU CẮT DANH SÁCH

3 loại danh sách trong Python là gì?Danh sách là một trong 4 loại dữ liệu tích hợp trong Python được sử dụng để lưu trữ các bộ sưu tập dữ liệu, 3 loại còn lại là Tuple, Set và Dictionary, all with different qualities and usage.
Danh sách () trong Python là gì?Hàm list() tạo đối tượng danh sách . Một đối tượng danh sách là một bộ sưu tập được sắp xếp và thay đổi. Đọc thêm về danh sách trong chương. Danh sách Python.
Danh sách hợp lệ là gì?Danh sách giá trị hợp lệ hoặc danh sách dữ liệu tham chiếu là tập hợp các giá trị có thể được phép sử dụng trong trường dữ liệu . Một danh sách giá trị hợp lệ thường được xác định cục bộ. Danh sách dữ liệu tham chiếu thường được xác định và duy trì bởi bên thứ ba và được chính thức áp dụng để sử dụng cục bộ trong một tổ chức. |
