我试图:
然而,当我尝试将密钥对转储到新的.json文件时,它只打印最后一个字典密钥对。有人知道如何遍历每个字典并附加密钥对吗?我试过一些方法,但我似乎弄不清我遗漏了什么和在哪里。
这是我的代码:
with open(join(dirname(__file__),'text.json')) as tone_json:
python_obj = json.load(tone_json) #read file object into string
my_list = python_obj["data"] #assign list name to string
for dictionary in my_list: #loop through dictionaries in list
for key,value in dictionary.items(): #loop through key pairs in dictionaries
if key == "text":
with open('comments.json', 'w') as f:
json.dump("{}: {}".format(key,value), f) #write key pair objects as json formatted stream to json file
f.write('\n')
我的JSON文件示例:
{
"data": [
{
"text": "apple",
"created_time": "2017-12-23",
"comment_count": 154,
"like_count": 856,
"id": "1015595299xxxxx"
},
{
"text": "orange",
"created_time": "2017-12-04",
"comment_count": 13,
"like_count": 437,
"id": "10155952xxxxx"
},
{
"text": "grapes",
"created_time": "2017-12-04",
"comment_count": 12,
"like_count": 163,
"id": "1015595299xxxxx"
}
]
}
我的电流输出:
"text: grapes"
但是,我想遍历每个字典,最终只打印每个“文本”键的值。
预期产量:
"text: apple"
"text: orange"
"text: grapes"
任何提示都有帮助!谢谢!
