如何在Python中保留前4个键并对JSON/Dict其余按键排序？

可以用Python直接实现这个需求，核心逻辑是先保留指定的固定键，再将剩余按键按字母顺序排序后拼接：

1. 提取top、left、width、height四个固定键，严格按要求的顺序保留
2. 筛选字典中除固定键外的所有按键，按字母顺序排序
3. 重新构建新字典，先放入固定键，再依次加入排序后的剩余按键

代码示例 #

original_dict = {
    "top": 590,
    "left": 105, 
    "width": 240, 
    "height": 40,

}

# 定义固定顺序的前置键
fixed_keys = ["top", "left", "width", "height"]
# 提取剩余按键并按字母排序
sorted_remaining_keys = sorted([k for k in original_dict if k not in fixed_keys])

# 构建新字典
sorted_dict = {}
# 先添加固定键
for key in fixed_keys:
    sorted_dict[key] = original_dict[key]
# 再添加排序后的剩余键
for key in sorted_remaining_keys:
    sorted_dict[key] = original_dict[key]

# 输出格式化后的结果
import json
print(json.dumps(sorted_dict, indent=4))

最终输出效果 #

运行代码后，生成的字典会先保留top、left、width、height的顺序，后续英雄按键按A-Z字母顺序排列：

{
    "top": 590,
    "left": 105,
    "width": 240,
    "height": 40,
