Question

我正在访问一个API，该API使我可以在给定的薪资期限内调入和调出员工的时间。此JSON输出包含大量我不需要的数据。我真正需要的只是员工ID号，他们的全名和当天的出勤记录。但是，我可以从中提取的最小数据集是整整一周。因此，如果我要获取今天的数据，则需要过滤一周中的其他几天。

到目前为止，我的方法一直是将所需的数据提取到字典中：基于特定键名的date_dict。问题是字典中充斥着每天的关键数据，而我只希望时间点包含今天的日期。下面是我用代码和生成代码的示例输出。下面是API输出的原始JSON数据

today = datetime.date.today().strftime("%Y-%m-%d")
parsed = "json data is here"

for item in parsed:
    date_dict={}
    date_dict['Employee']=item.get('Employee').get('EmployeeId')
    date_dict['EmployeeName']=item.get('Employee').get('FullName')
    date_dict['PunchInDateTime']=item.get('PunchInDateTime')
    date_dict['PunchOutDateTime']=item.get('PunchOutDateTime')
    print date_dict

{'Employee': u'080097', 'PunchInDateTime': u'2019-06-18T08:43:00', 'PunchOutDateTime': u'2019-06-18T13:43:00', 'EmployeeName': u'Peter Quill'}
{'Employee': u'080097', 'PunchInDateTime': u'2019-06-19T08:00:00', 'PunchOutDateTime': u'2019-06-19T09:16:00', 'EmployeeName': u'Peter Quill'}

基本上我的输出中是这样的：

{'Employee': u'080097', 'PunchInDateTime': u'2019-06-18T08:43:00', 'PunchOutDateTime': u'2019-06-18T13:43:00', 'EmployeeName': u'Peter Quill'}
{'Employee': u'080097', 'PunchInDateTime': u'2019-06-19T08:00:00', 'PunchOutDateTime': u'2019-06-19T09:16:00', 'EmployeeName': u'Peter Quill'}

我想得到的是因为打孔只包含今天的日期：

{'Employee': u'080097', 'PunchInDateTime': u'2019-06-19T08:00:00', 'PunchOutDateTime': u'2019-06-19T09:16:00', 'EmployeeName': u'Peter Quill'}

我只是不知道如何到达那里，因为我不能只删除键或值，因为那里有重复项，而且我确实需要employeeid和fullname值。而且我希望能够在一天内为所有员工执行此操作，因此我也无法对特定值进行硬编码。

编辑：这是脚本后面的一些代码，可循环访问字典并帮助准备要插入db的sql语句。目前，我只是在打印它，所以可以验证它是否正常工作。但是，当我通过它运行新的date_dict时，出现错误：TypeError：字符串索引必须是整数，而不是str

timepunches_dict = date_dict

for i, punch in enumerate(timepunches_dict):
        punch_in = punch['PunchInDateTime']
        punch_out = punch['PunchOutDateTime']
        punch_in_sql = punch_in.replace('T', ' ')
        punch_out_sql = punch_out.replace('T', ' ')

        emp_id = punch['Employee']['EmployeeId']
        emp_name = punch['Employee']['FullName']

        if today in punch_in_sql:
            if i == 0:
            # ONLY RUN FOR FIRST ITERATION 
                print(emp_id, today, emp_name)

        # RUN FOR ALL ITERATIONS
            print(emp_id, today, i+1, punch_in_sql, punch_out_sql)

如果您不在乎时间，则可以根据'PunchInDateTime'拆分T并在if条件下使用：

for item in parsed:
date_dict={}
date_dict['PunchInDateTime']=item.get('PunchInDateTime').split('T', 1)[0]

if  date_dict['PunchInDateTime'] == today :
    date_dict['Employee']=item.get('Employee').get('EmployeeId')
    date_dict['EmployeeName']=item.get('Employee').get('FullName')
    date_dict['PunchInDateTime']=item.get('PunchInDateTime')
    date_dict['PunchOutDateTime']=item.get('PunchOutDateTime')
    print date_dict

输出：

{'Employee': u'080097', 'PunchInDateTime': u'2019-06-19T08:00:00', 'PunchOutDateTime': u'2019-06-19T09:16:00', 'EmployeeName': u'Peter Quill'}

如何根据今天的日期从JSON输出中提取特定数据
