Toán tử được sử dụng để thực hiện các thao tác trên các giá trị và biến. Đây là những ký hiệu đặc biệt thực hiện các phép tính số học và logic. Giá trị mà toán tử thao tác được gọi là Toán hạng Show
Toán tử logicTrong Python, các toán tử logic được sử dụng trên các câu điều kiện (Đúng hoặc Sai). Chúng thực hiện các phép toán logic AND, logic OR và logic NOT HOẠT ĐỘNG MÔ TẢCÚ pháp và logic VÀ. Đúng nếu cả hai toán hạng là truex và yorLogical OR. True nếu một trong hai toán hạng là truex hoặc ynotLogical NOT. True nếu toán hạng là falsenot xBảng chân lý cho tất cả các tổ hợp giá trị của X và YBảng sự thật Toán tử logic ANDToán tử logic trả về True nếu cả hai toán hạng đều True, ngược lại nó trả về False.

Cả hai đều yêu cầu hai toán hạng có thể đánh giá là đúng hoặc sai.
làm gì. == Có nghĩa là gì trong Python?Trong bài viết này, chúng ta sẽ xem. = (Không bằng) toán tử. Trong Python. = được định nghĩa là không bằng toán tử . Nó trả về True nếu toán hạng ở hai bên không bằng nhau và trả về False nếu chúng bằng nhau.
&= trong Python là gì?Có nghĩa là hoạt động AND theo bit . Ví dụ. x = 5 x &= 3 #tương tự như x = x & 3 print(x)
