Python có thể đặt trùng lặp không?
Bài viết này tập trung vào một trong các thao tác lấy một danh sách duy nhất từ một danh sách có chứa danh sách trùng lặp có thể xảy ra. Loại bỏ các bản trùng lặp khỏi thao tác danh sách có một số lượng lớn các ứng dụng và do đó, kiến thức về nó là tốt để có. Show
Phương pháp 1. Sử dụng *set()Đây là phương pháp nhanh nhất và nhỏ nhất để đạt được một nhiệm vụ cụ thể. Đầu tiên, nó loại bỏ các bản sao và trả về một từ điển phải được chuyển đổi thành danh sách.

Nó mô hình trừu tượng tập hợp toán học.
Một tập hợp có thể trùng lặp toán học không?Bộ cũng có thể là bộ nhiều bộ (túi có túi bên trong). Tuy nhiên, một tập hợp không thể chứa các mục trùng lặp -- một tập hợp chỉ có thể chứa một bản sao của một mục cụ thể. Ví dụ, khi chúng ta nhìn vào các tập hợp của một số loại số, chẳng hạn như số tự nhiên hoặc số hữu tỷ, chúng ta có thể chỉ muốn nói về các tập hợp này.
