[英]Python: write json list result into JSON file
So I have this kind of data received:所以我收到了这种数据:
[{
'Status': 0,
'Button': False,
'Message': None,
'Id': None,
'hu': 0,
'Mode': 'LocModePresence',
'mac': '00011171815E',
'mapId': '17_1_0',
'Seq': 236,
'tam': False,
'temperature': 0.0,
'time': 1603797352911,
'type': 'TTT',
'x': 2716.0,
'y': 648.0,
'zone': '301990146'
}, {
'Status': 0,
'Button': False,
'Message': '6e0002000c00',
'Id': '3_2',
'hu': 0,
'Mode': 'LocModePresence',
'mac': '00011171815E',
'mapId': '17_1_0',
'Seq': 237,
'tam': False,
'temperature': 0.0,
'time': 1603797357105,
'type': 'TTT',
'x': 2716.0,
'y': 648.0,
'zone': '301990146'
}]
And I want to write it into JSON
file:我想把它写入
JSON
文件:
with open('data.json', 'w', encoding='utf-8') as f:
json.dump(my_data, f, ensure_ascii=False, indent=4)
If i want to take this data that have as string (for debug reason) why when I put it inside 2 '
sign this show me error
:如果我想把这个数据作为字符串(出于调试原因),为什么当我把它放在 2
'
中时,这个符号会显示error
:
illegal target for variable annotation
I want to be able to write this on my disk and also read it to compare to another file that I will get (and also this file need to be write on the disk)我希望能够将其写入我的磁盘并读取它以与我将获得的另一个文件进行比较(并且该文件也需要写入磁盘)
When you read from the file you should use read()
.当您从文件中读取时,您应该使用
read()
。
The different between read()
readline()
and readline()
are documented here: read()
readline()
和readline()
之间的区别记录在此处:
When should I ever use file.read() or file.readlines()? 我什么时候应该使用 file.read() 或 file.readlines()?
import json
my_data = [
{
'Status': 0,
'Button': False,
'Message': None,
'Id': None,
'hu': 0,
'Mode': 'LocModePresence',
'mac': '00011171815E',
'mapId': '17_1_0',
'Seq': 236,
'tam': False,
'temperature': 0.0,
'time': 1603797352911,
'type': 'TTT',
'x': 2716.0,
'y': 648.0,
'zone': '301990146',
},
{
'Status': 0,
'Button': False,
'Message': '6e0002000c00',
'Id': '3_2',
'hu': 0,
'Mode': 'LocModePresence',
'mac': '00011171815E',
'mapId': '17_1_0',
'Seq': 237,
'tam': False,
'temperature': 0.0,
'time': 1603797357105,
'type': 'TTT',
'x': 2716.0,
'y': 648.0,
'zone': '301990146',
},
]
if __name__ == '__main__':
with open('data.json', 'w', encoding='utf-8') as _file:
json.dump(my_data, _file, ensure_ascii=False, indent=4)
with open('data.json', 'r', encoding='utf-8') as _file:
str_content = _file.read()
print(type(str_content))
json_content = json.loads(str_content)
print(type(json_content))
