我想选择某些键的值,例如“用户”键中的“文本”、“位置”和“地点”中的“边界框”中的“坐标”
有几个选择是成功的,但是当我想在“place”中的“bounding\u box”中选择“coordinates”时,它给出了一个错误:“NoneType”对象是不可下标的
这是我的密码: 以下4条线路全部工作:
all_id_str = [one_read['id_str'] for one_read in json_read]
all_text = [one_read['text'] for one_read in json_read]
all_coord = [one_read['coordinates'] for one_read in json_read]
all_location = [one_read['user']['location'] for one_read in json_read]
但以下两行与“地点”相关的内容不起作用:
all_country= [one_read['place']['country'] for one_read in json_read]
all_bbox = [one_read['place']['bounding_box'] for one_read in json_read]
TypeError回溯(最近一次调用) 在
----> 1 all_country= [one_read['place']['country'] for one_read in json_read]
2 all_bbox = [one_read['place']['bounding_box'] for one_read in json_read]
在(.0)中
----> 1 all_country= [one_read['place']['country'] for one_read in json_read]
2 all_bbox = [one_read['place']['bounding_box'] for one_read in json_read]
TypeError:“NoneType”对象不可订阅
我测试了是否有任何一个字典包含键“place”的none/null值,但它们都返回空[]
[one_read for one_read in json_read if one_read['place'] == 'None']
[one_read for one_read in json_read if one_read['place'] == 'Null']
输出: []
有人能帮忙吗
one_read['place']
无效你应该做
one_read['user']['place']['country']
