Có thể có bản sao trong từ điển python không?
Công cụ sau đây trực quan hóa những gì máy tính đang làm từng bước khi nó thực thi chương trình nói trên Show Trình chỉnh sửa mã Python Có một cách khác để giải quyết giải pháp này? Trước. Viết chương trình Python để lấy từ điển từ các trường của đối tượng. Mức độ khó của bài tập này là gì? Dễ dàng trung bình khóKiểm tra kỹ năng Lập trình của bạn với bài kiểm tra của w3resource Chia sẻ Hướng dẫn / Bài tập này trên. Facebook và Twitter con trăn. Lời khuyên trong ngàyĐảo ngược dữ liệu (Hàm đảo ngược & Phương pháp đảo ngược) Hàm đảo ngược và phương thức đảo ngược chỉ có thể được sử dụng để đảo ngược các đối tượng trong Python. Nhưng có một sự khác biệt lớn giữa hai Từ điển Python không cho phép lặp lại khóa. Tuy nhiên, chúng ta có thể sử dụng defaultdict để tìm cách giải quyết. Lớp này được định nghĩa trong mô-đun bộ sưu tập Sử dụng danh sách làm nhà máy mặc định cho đối tượng defaultdict >>> from collections import defaultdict >>> d=defaultdict(list) Dưới đây là danh sách các bộ dữ liệu có hai mục. Mục đầu tiên được tìm thấy được sử dụng nhiều lần. Danh sách này được chuyển đổi trong defaultdict Trong khi xử lý từ điển, chúng ta có thể gặp tình huống khi có các giá trị trùng lặp trong từ điển trong khi rõ ràng các khóa vẫn là duy nhất. Trong bài viết này, chúng ta sẽ xem làm thế nào chúng ta có thể đạt được Trao đổi khóa và giá trịChúng tôi trao đổi các khóa với các giá trị của từ điển và sau đó tiếp tục nối thêm các giá trị được liên kết với một khóa đã cho. Bằng cách này, các giá trị trùng lặp được xếp vào nhóm và chúng ta có thể thấy chúng trong từ điển mới kết quả Thí dụBản thử trực tiếp dictA = {'Sun': 5, 'Mon': 3, 'Tue': 5, 'Wed': 3} print("Given Dictionary :", dictA) k_v_exchanged = {} for key, value in dictA.items(): if value not in k_v_exchanged: k_v_exchanged[value] = [key] else: k_v_exchanged[value].append(key) # Result print("New Dictionary:", k_v_exchanged) đầu raChạy đoạn mã trên cho chúng ta kết quả sau - Given Dictionary : {'Sun': 5, 'Mon': 3, 'Tue': 5, 'Wed': 3} New Dictionary: {5: ['Sun', 'Tue'], 3: ['Mon', 'Wed']} với bộchúng tôi làm theo một cách tiếp cận tương tự ở đây. Ở đây, chúng tôi cũng tạo một từ điển mới từ từ điển hiện có bằng cách sử dụng chức năng thiết lập và thêm các khóa có giá trị trùng lặp. Cuối cùng, chúng tôi lọc ra các giá trị có độ dài lớn hơn 1 và đánh dấu chúng là trùng lặp Đưa ra một từ điển, nhiệm vụ là tìm các khóa có giá trị trùng lặp. Hãy thảo luận về một vài phương pháp cho cùng một Phương pháp #1.

. Không cho phép sao chép khóa . Từ điển ánh xạ mỗi khóa thành một giá trị tương ứng, vì vậy sẽ không hợp lý khi ánh xạ một khóa cụ thể nhiều lần.
Từ điển có cho phép các thành viên trùng lặp không?Từ điển là một bộ sưu tập không có thứ tự, có thể thay đổi và lập chỉ mục. Không có thành viên trùng lặp .
Từ điển trong Python có thể có cùng giá trị không?Không, mỗi khóa trong từ điển phải là duy nhất . Bạn không thể có hai khóa có cùng giá trị. Cố gắng sử dụng lại cùng một khóa sẽ chỉ ghi đè lên giá trị được lưu trữ trước đó. Nếu một khóa cần lưu trữ nhiều giá trị thì giá trị được liên kết với khóa phải là một danh sách hoặc một từ điển khác. |
