Question

这是我的JSON响应，我想删除整个meta标头部分。

{
    "meta": {
        "limit": 1000,
        "next": "https://cisco-demo.obsrvbl.com/api/v3/observations/all/?limit=1000&offset=1000",
        "offset": 0,
        "previous": null,
        "total_count": 1863020
    },
    "objects": [
        {
            "creation_time": null,
            "end_time": "2017-08-17T19:40:00Z",

Answer 1

import json

with open('myfile.txt') as fp:
    my_dict = json.loads(fp.read())

try:
    del my_dict['meta']
except KeyError:
    pass

我假设您已经将JSON作为字典，在上面的代码中，我只是从文本文件加载它。您要查找的命令是del。最好将它放在try / catch块中，以防万一您正在处理没有meta字段的字典，因为在这种情况下，它将抛出KeyError并中断。
