Rất dễ viết mã bằng Python để trả về dữ liệu danh sách từ các hàm. Một danh sách chứa nhiều giá trị nên hàm sẽ trả về nhiều giá trị
Hàm ví dụ trả về danh sách trong Python
Mã ví dụ đơn giản
Nhìn vào chức năng dưới đây. Nó trả về một danh sách chứa mười số
def ret_list(): list1 = [] for i in range(0, 10): list1.append(i) return list1 print(ret_list())đầu ra. [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Một vi dụ khac. Hàm này trả về một danh sách
Giá trị trả về trong danh sách chứa chuỗi và số
def fun(): str1 = "Hello" x = 100 return [str1, x] # Driver code print(fun())đầu ra
Hãy bình luận nếu bạn có bất kỳ câu hỏi hoặc đề xuất nào về chủ đề trả về chức năng python này
