Question

我只有几个静态键列EmployeeId，type和几个列来自第一个FOR循环。

在第二个FOR循环中，如果我有特定的键，则仅应将值附加到现有的数据帧列上，否则从第一个for循环中获取的列应保持不变。

第一个循环输出：

"EmployeeId","type","KeyColumn","Start","End","Country","Target","CountryId","TargetId"
"Emp1","Metal","1212121212","2000-06-17","9999-12-31","","","",""

在“第二次循环”之后，我的输出如下：

"EmployeeId","type","KeyColumn","Start","End","Country","Target","CountryId","TargetId"
"Emp1","Metal","1212121212","2000-06-17","9999-12-31","","AMAZON","1",""
"Emp1","Metal","1212121212","2000-06-17","9999-12-31","","FLIPKART","2",""

根据代码，如果我有Employee标签可用，我有2条以上的记录，但是我可能有一些没有Employee标签的json文件，则输出应与First Loop Output相同。

但是根据我的代码，我得到了0条记录。如果我的编码方式有误，请帮助我。

真的很抱歉-如果询问方式不清楚，因为我是python的新手。请在下面的超级链接中找到代码

请找到以下代码

    for i in range(len(json_file['enty'])):
        temp = {}
        temp['EmployeeId'] = json_file['enty'][i]['id']
        temp['type'] = json_file['enty'][i]['type']
        for key in json_file['enty'][i]['data']['attributes'].keys(): 
            if(key == 'Employee'):
                for j in range(len(json_file['enty'][i]['data']['attributes']['Employee']['group'])):
                    for key in json_file['enty'][i]['data']['attributes']['Employee']['group'][j].keys():
                        try:
                            temp[key] = json_file['enty'][i]['data']['attributes']['Employee']['group'][j][key]['values'][0]['value']
                        except:
                            temp[key] = None

                    temp_df = pd.DataFrame([temp])
                    df = pd.concat([df, temp_df], sort=True)

如果雇员标签不可用，我将获得0条记录作为输出，但我希望有1条记录作为第一个for循环

如果Python中不存在For循环迭代，则获取空值
