Đảo 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 trị
Chúng 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 dụ
Bản 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]

Chạy 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 bộ
chúng 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. Sử dụng phương pháp Naive
Trước tiên, trong phương pháp này, chúng tôi chuyển đổi các giá trị trong từ điển thành các khóa bằng ánh xạ nghịch đảo, sau đó tìm các khóa trùng lặp
