Các đối tượng là các thể hiện của lớp trong python có các trường và phương thức tôi. e. , giá trị và các chức năng liên quan
Python cho phép các lập trình viên của nó truyền đối tượng vào phương thức. Và cũng trả về các đối tượng từ một phương thức. Đây là một chương trình để minh họa điều này,
Một hàm có thể nhận nhiều đối số, các đối số này có thể là đối tượng, biến [cùng hoặc khác kiểu dữ liệu] và hàm. Hàm Python là đối tượng hạng nhất. Trong ví dụ bên dưới, một hàm được gán cho một biến. Bài tập này không gọi hàm. Nó lấy đối tượng hàm được tham chiếu bởi hét và tạo một tên thứ hai trỏ tới nó, hét

Hàm bậc cao hơn
Vì hàm là đối tượng nên chúng ta có thể chuyển chúng làm đối số cho các hàm khác. Các hàm có thể nhận các hàm khác làm đối số còn được gọi là hàm bậc cao. Trong ví dụ bên dưới, một hàm hello được tạo lấy một hàm làm đối số

chức năng bao bọc
Hàm trình bao bọc hoặc trình trang trí cho phép chúng ta bao bọc một hàm khác để mở rộng hành vi của hàm được bao bọc mà không sửa đổi vĩnh viễn nó. Trong Decorators, các hàm được lấy làm đối số cho một hàm khác và sau đó được gọi bên trong hàm bao bọc. Để biết thêm về trang trí bấm vào đây

Hàm bao bọc Lambda
Trong Python, hàm ẩn danh có nghĩa là một hàm không có tên. Như chúng ta đã biết rằng từ khóa
HI, I AM CREATED BY A FUNCTION PASSED AS AN ARGUMENT. hi, i am created by a function passed as an argument.0 được sử dụng để xác định các hàm thông thường và từ khóa
HI, I AM CREATED BY A FUNCTION PASSED AS AN ARGUMENT. hi, i am created by a function passed as an argument.15 được sử dụng để tạo các hàm ẩn danh. Hàm này có thể có bất kỳ số lượng đối số nào nhưng chỉ có một biểu thức, được đánh giá và trả về. Hàm lambda cũng có thể có một hàm khác làm đối số. Ví dụ dưới đây cho thấy một hàm lambda cơ bản trong đó một hàm lambda khác được truyền dưới dạng đối số

Python có truyền đối tượng theo tham chiếu không?
Python luôn sử dụng các giá trị truyền qua tham chiếu. Không có bất kỳ ngoại lệ. Bất kỳ phép gán biến nào có nghĩa là sao chép giá trị tham chiếu
Các tham số được truyền cho các hàm trong Python như thế nào?
Thông tin có thể được truyền vào hàm dưới dạng đối số. Các đối số được chỉ định sau tên hàm, bên trong dấu ngoặc đơn . Bạn có thể thêm bao nhiêu đối số tùy thích, chỉ cần phân tách chúng bằng dấu phẩy.
Chúng ta có thể chuyển các đối tượng lớp dưới dạng đối số hàm trong Python không?
Một hàm có thể nhận nhiều đối số, các đối số này có thể là đối tượng, biến [cùng hoặc khác kiểu dữ liệu] và hàm . Hàm Python là đối tượng hạng nhất. Trong ví dụ bên dưới, một hàm được gán cho một biến.
Bạn có thể chuyển một đối tượng làm tham số trong Python không?
Đối tượng là Đối số và Tham số. Bạn có thể truyền đối tượng làm đối số cho hàm theo cách thông thường .
