我有一个 JSON data_request.json 文件：

            "replaceText": "str(try_description)"

    }
]

Python 代码：

with open("data_request.json", "r") as json_data:
    data = load(json_data)

    empty_list: list = []

    for element in data:
        # Step 1: Got all values from JSON
        all_elements: str = element["replaceAllText"]["replaceText"]
        print(all_elements)

        # Step 2: Trying append to `list()`.
        empty_list.append(all_elements)
        print(empty_list)

第 1 步的标准输出：

replaced['host']
replaced['company']
replaced['between_dates'][0]
replaced['between_dates'][1]
replaced['current_date']
replaced['sla']
replaced['total_tickets']
replaced['count_open_issues']
replaced['report_by_sla']['average']
replaced['report_by_sla']['test']
replaced['report_by_sla']['down']
replaced['report_by_sla']['goal']
replaced['host']
replaced['url_response']
self.url_response_time_goal
str(datetime.fromtimestamp(try_last_change))
await match_priority(try_priority)
str(try_description)

第 2 步的标准输出：

["replaced['host']"]
["replaced['host']", "replaced['company']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']"]

["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']"]
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']"]

["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']", "replaced['url_response']", 'self.url_response_time_goal']
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']", "replaced['url_response']", 'self.url_response_time_goal', 'str(datetime.fromtimestamp(try_last_change))']
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']", "replaced['url_response']", 'self.url_response_time_goal', 'str(datetime.fromtimestamp(try_last_change))', 'await match_priority(try_priority)']
["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']", "replaced['url_response']", 'self.url_response_time_goal', 'str(datetime.fromtimestamp(try_last_change))', 'await match_priority(try_priority)', 'str(try_description)']

如何获取所有值并将它们添加到数组中？我的意思是只获取最后一个值：

["replaced['host']", "replaced['company']", "replaced['between_dates'][0]", "replaced['between_dates'][1]", "replaced['current_date']", "replaced['sla']", "replaced['total_tickets']", "replaced['count_open_issues']", "replaced['report_by_sla']['average']", "replaced['report_by_sla']['test']", "replaced['report_by_sla']['down']", "replaced['report_by_sla']['goal']", "replaced['host']", "replaced['url_response']", 'self.url_response_time_goal', 'str(datetime.fromtimestamp(try_last_change))', 'await match_priority(try_priority)', 'str(try_description)']

当我访问第一个索引时，我得到以下信息：

print(empty_list[0])

replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']
replaced['host']

    【解决方案1】： 
    import json
with open("data_request.txt", "r") as json_data:
    data = json.load(json_data)
    all_replace_text = [item["replaceAllText"]["replaceText"] for item in data]
