Một số kiểu dữ liệu được đề cập dưới đây sẽ giúp tạo ra một mảng các kiểu dữ liệu khác nhau.
Thêm các phần tử vào một mảng
Các phần tử có thể được thêm vào Mảng bằng cách sử dụng hàm chèn [] tích hợp sẵn. Chèn được sử dụng để chèn một hoặc nhiều phần tử dữ liệu vào một mảng. Dựa trên yêu cầu, một phần tử mới có thể được thêm vào đầu, cuối hoặc bất kỳ chỉ mục nào của mảng. append[] cũng được sử dụng để thêm giá trị được đề cập trong các đối số của nó vào cuối mảng.

Loại bỏ các phần tử khỏi mảng
Có thể xóa các phần tử khỏi mảng bằng cách sử dụng hàm remove[] tích hợp nhưng sẽ xảy ra Lỗi nếu phần tử không tồn tại trong tập hợp. Phương thức Remove[] chỉ xóa một phần tử tại một thời điểm, để xóa phạm vi phần tử, trình vòng lặp được sử dụng. hàm pop[] cũng có thể được sử dụng để xóa và trả về một phần tử khỏi mảng, nhưng theo mặc định, hàm này chỉ xóa phần tử cuối cùng của mảng, để xóa phần tử khỏi một vị trí cụ thể của mảng, chỉ số của phần tử được truyền dưới dạng
Lưu ý – Phương thức xóa trong Danh sách sẽ chỉ xóa lần xuất hiện đầu tiên của phần tử được tìm kiếm.

Chúng ta có thể sử dụng mảng trong Python không?
Python có một tập hợp các phương thức tích hợp mà bạn có thể sử dụng trên danh sách/mảng. Ghi chú. Python không có hỗ trợ tích hợp cho Mảng, nhưng có thể sử dụng Danh sách Python để thay thế
Có cần khai báo mảng trong Python không?
Mảng được tạo trong Python bằng cách nhập mô-đun mảng vào chương trình python. Sau đó, mảng được khai báo như hình bên dưới. Trước khi xem xét các thao tác mảng khác nhau, hãy tạo và in một mảng bằng python.
Tại sao mảng không được sử dụng trong Python?
Python không có cấu trúc dữ liệu mảng gốc , nhưng nó có danh sách có thể thay đổi, nghĩa là chúng ta có thể sửa đổi nội dung có trong danh sách. Chúng tôi có thể lưu trữ dữ liệu của các kiểu dữ liệu không đồng nhất. Danh sách tổng quát hơn nhiều và có thể được sử dụng như một mảng đa chiều khá dễ dàng.
Làm thế nào tôi có thể khai báo một mảng?
Để tạo một mảng, xác định kiểu dữ liệu [như int ] và chỉ định tên của mảng theo sau bởi dấu ngoặc vuông [] . Để chèn giá trị vào nó, hãy sử dụng danh sách được phân tách bằng dấu phẩy, bên trong dấu ngoặc nhọn. int myNumbers[] = {25, 50, 75, 100};
