    The combination of above functions can be used to solve this problem. In this, we iterate for all the keys and delete the required key from each dictionary using del.

    Python3

    Đôi khi, trong khi làm việc với từ điển Python, chúng ta có thể gặp vấn đề trong đó chúng ta cần xóa một khóa cụ thể khỏi danh sách từ điển. Loại vấn đề này là rất phổ biến và có ứng dụng trong hầu hết các lĩnh vực bao gồm lập trình hàng ngày và miền phát triển web. Hãy để thảo luận về những cách nhất định trong đó nhiệm vụ này có thể được thực hiện.

    Phương pháp số 1: Sử dụng Loop + 

    The original list is : [{'best': 8, 'id': 2, 'Gfg': 1}, {'best': 10, 'id': 4, 'Gfg': 4}, {'best': 11, 'id': 8, 'Gfg': 4}]
The modified list : [{'best': 8, 'Gfg': 1}, {'best': 10, 'Gfg': 4}, {'best': 11, 'Gfg': 4}]
    1 Sự kết hợp của các hàm trên có thể được sử dụng để giải quyết vấn đề này. Trong đó, chúng tôi lặp lại cho tất cả các phím và xóa phím cần thiết khỏi mỗi từ điển bằng DEL.

    10pop[] can be used to delete a key and its value inplace. The advantage over using del is that it provides the mechanism to print desired value if tried to remove a non-existing dict. pair. Second, it also returns the value of the key that is being removed in addition to performing a simple delete operation. Demonstrating key-value pair deletion using pop[]

    Phương pháp 3: Sử dụng các mục [] + Dictribution để xóa khóa khỏi từ điển

    Python3

    Các mục [] cùng với sự hiểu biết của Dict cũng có thể giúp chúng ta đạt được nhiệm vụ xóa cặp giá trị khóa, nhưng, nó có nhược điểm của việc không phải là một điều kiện tại chỗ. kĩ thuật. Trên thực tế, một dict mới được tạo ra ngoại trừ chìa khóa mà chúng tôi không muốn bao gồm. Thể hiện Xóa cặp giá trị khóa bằng cách sử dụng các mục [] + Dictlement.
