Hướng dẫn how to delete a key from ordered dictionary in python - cách xóa khóa khỏi từ điển đã đặt hàng trong python
Tôi đang cố gắng xóa một khóa và giá trị khỏi 3 nhưng khi tôi sử dụng: Show
Nó loại bỏ khóa và giá trị cuối cùng ngay cả khi một khóa khác được cung cấp. Có thể xóa một khóa ở giữa nếu từ điển? Đã hỏi ngày 26 tháng 11 năm 2014 lúc 17:53Nov 26, 2014 at 17:53
5 Có, bạn có thể sử dụng 4:
Dưới đây là một cuộc biểu tình:

so that it can be saved for later. If you do not need to save it however, then using these methods is less efficient.Đã trả lời ngày 26 tháng 11 năm 2014 lúc 17:54Nov 26, 2014 at 17:54 Bạn có thể sử dụng pop, popitem loại bỏ lần cuối cùng theo mặc định:
