As a json response I got it from server
{"Data":["{\"item1\": \"value1\",\"item2\": \"value2\"}"]}
I used
a=json.loads(response)
print(a)
self.write(a)
From terminal I saw
{u'Data':[u'{"item1": "value1", "item2": "value2"}"]'}
From postman it's like
{"Data":["{\"item1\": \"value1\",\"item2\": \"value2\"}"]}
I need as
{"Data":[{"item1": "value1","item2": "value2"}]}
I know all this format are right but I prefer the last format in postman. Thanks in advance
I tried the below and it works...
content = json.loads(content)['data']
temp = []
for values in content:
jstr = json.loads(values)
temp.append(jstr)
val = {"data": temp}
self.write(json.dumps(val))

I have this one problem, where I print out a message response from a website(JSON response), and the response I get is this.
Here is my model with fake data:
{"token": "MTAxOTAwNjM4NjEyMzg0OTkwMQ.8hkyLV.n0ir2UA4qFE5pXen9YnPtFzgn4xP8tHmVmmkrl", "user_settings": {"locale": "en-US", "theme": "dark"}, "user_id": "101900638614857883"}
And, if I only want the value of "token" data which are this (MTAxOTAwNjM4NjEyMzg0OTkwMQ.8hkyLV.n0ir2UA4qFE5pXen9YnPtFzgn4xP8tHmVmmkrl) and I want to store it into a txt file, is there any good way to do it?
Thank you, guys!
I tried print(r.text('token')) but it did not work, since it only works on printing the category of the data's (like : Category : {"token" : 'daefafa', "user-id" : 'er121231231', more})
In python, JSON is treated as a dictionary.
To filter it use dictionary comprehension
tokenData = {key: val for key,val in data_json.items() if key == 'token'}
Full Code Snippet :
from urllib.request import urlopen
import json
url = "enter-your-url"
response = urlopen(url)
data_json = json.loads(response.read())
print(type(data_json)) # <class 'dict'>
#use dict comprehension
jsonToken = {key: val for key,val in data_json.items() if key == 'result'}
strToken = json.dumps(jsonToken)
# Only string json can be written to files
with open('data.txt','w') as file:
file.write(strToken)
file.close()
You need to parse the JSON into a dictionary using json.loads(). Like this:
import json
# ...
# request-getting code
# ...
data = json.loads(r.text)
print(data['token'])
I'm getting below output from an API and I want to read all purchaseOrder data. Not really sure how to loop on this data. Also it comes with b' at the front.
b'[
{"purchaseOrder":
[
{

}
],
"salesOrder":null,
"agreement":null,
"status":""
}
]'
Have tried things like loaded_json = json.load(r.content) and it didn't work.
This is code I use to get the response:
r = requests.post(url=api_endpoint, data=json.dumps(json_post), headers=headers)
To get the json of a response use data = response.json().
After that you can step through it like normal lists and dicts:
import json
data = r.json()
print(json.dumps(data , indent=2)) # If you want to see the data from the response
for dic in data :
if 'purchaseOrder' in dic:
for item in dic['purchaseOrder']:
# item here is the `dict` for each purchaseOrder (PO).
print(json.dumps(item, indent=2)) # This will print each item in PO.
Thanks all for support. The next code works for me:
data = r.json()
print(json.dumps(data, indent=2))
for dic in data:
if 'purchaseOrder' in dic:
for itemdata in dic['purchaseOrder']:
for key in itemdata:
if key == 'id':
print("Id:")
print(itemdata['id'])
print("Price:")
print(itemdata['price'])
I have a big tree in a JSON file and I'm searching the python syntax for loading nested in nested keys from this JSON.
Assume I have this :
{
"FireWall": {
"eth0": {
"INPUT": {
"PING": 1,
}
}
}
}
According to the man page and some questions in Stackoverflow i tried this (and some variations) :
import json
config = open('config.json', 'r')
data = json.load('config')
config.close()
if data['{"FireWall", {"eth0", {"INPUT", {"Ping"}}}}'] == 1:
print('This is working')
With no result. What is the right way to do this (as simple as possible) ? Thank you !
You are trying data = json.load('config') to load string not file object and data['{"FireWall", {"eth0", {"INPUT", {"Ping"}}}}'] it's not right way to access nested dictionary key value.
import json
with open('config.json', 'r') as f:
data = json.load(f)
if data["FireWall"]["eth0"]["INPUT"]["Ping"] == 1:
print('This is working')
data is a nested dictionary, so:
data["FireWall"]["eth0"]["INPUT"]["Ping"]
will be equal to 1; or at least it will when you fix your call to json.load.
Try this:
data["FireWall"]["eth0"]["INPUT"]["PING"]
This will give you the value in PING
dct_data = json_tour_data.__dict__
tour_data = json.dumps(dct_data)
How to remove these backslashes from json? Here is my output:
"{\"strFileOpenDateAjxKey\": \"2018-01-16 12:40:22.526417\",
\"strFilePassengerAjxKey\": \"Zahra Walji\", \"strFileOpenMobileAjxKey\":
\"46464664\", \"strFileOpenDepartmentAjxKey\": \"Finance department\",
\"strFileOpenAccountCodeAjxKey\": \"CARTZS\",
\"strFileOpenProfileCodeAjxKey\": \"CARTZS\",
\"strFileopenOriginalCountryIdAjxKey\": 61, \"blnBoundAjxKey\": 1,
\"strTransactionCurrencyJsKey\": \"Shillings\",
\"intCurrencyPrecisionJsKey\": 3, \"strPackageTypeJsKey\": \"PKG\",
\"strUserNameAjxKey\": \"admin\", \"strPasswordAjxKey\": \"1234\"}"
The answer is you have to just play with json.dumps() and json.loads().
The following is my code which worked:-
import json
json_data = {'key1': 'first'}
json_data = json.dumps(json_data)
return {
'statusCode': 200,
'schools': json.loads(json_data)
}
The output of above code is as follows:
Response:
{
"schools": {
"key1": "first"
},
"statusCode": 200
}
I would recommend checking your Response object where your parse your tour_data variable/dictionary in your views. I originally had the same issue as you but here's what I changed.
Original implementation: Response(json.dumps(a_dictionary), status=status.HTTP_200_OK)
to
New implementation: Response(a_dictionary, status=status.HTTP_200_OK, content_type='json')
The key things here are:
1. Getting rid of the json.dumps conversion method and just pass through a plain python dictionary e.g. see a_dictionary.
2. Setting content_type='json' on the Response object.
you can use replace("\'", '"') for that.
json = '''{\"strFileOpenDateAjxKey\": \"2018-01-16 12:40:22.526417\",
\"strFilePassengerAjxKey\": \"Zahra Walji\", \"strFileOpenMobileAjxKey\":
\"46464664\", \"strFileOpenDepartmentAjxKey\": \"Finance department\",
\"strFileOpenAccountCodeAjxKey\": \"CARTZS\",
\"strFileOpenProfileCodeAjxKey\": \"CARTZS\",
\"strFileopenOriginalCountryIdAjxKey\": 61, \"blnBoundAjxKey\": 1,
\"strTransactionCurrencyJsKey\": \"Shillings\",
\"intCurrencyPrecisionJsKey\": 3, \"strPackageTypeJsKey\": \"PKG\",
\"strUserNameAjxKey\": \"admin\", \"strPasswordAjxKey\": \"1234\"}'''
newString = json.replace("\'", '"')
print(newString)
check from here
that is the output when pressed the run in my side.
To anyone else who might be facing this issue.
simply put:
the original question seems to be taking JSON data (I emphasize, it's already JSON) and rendering it into JSON again.
dct_data = json_tour_data.dict
tour_data = json.dumps(dct_data)
I'm trying to work with dictionaries inside a list in a JSON file. The data imports fine and reads fine. For the life of me I can't figure out how to printout the "member_id" keys. I just want to print the list of "member_id" numbers. I was initially using json.loads, then switched to json.dumps. Any help would really be appreciated.
import urllib2
import json
nyt_api_key = '72c9a68bbc504e91a3919efda17ae621%3A7%3A70586819'
url= 'http://api.nytimes.com/svc/politics/v3/us/legislative/congress/113'
json_obj = urllib2.urlopen(url)
data = json.load(json_obj)
data2 = json.dumps(data, sort_keys=True, indent=True, skipkeys = True)
print data2
Output from print data2: (The list goes on and on so it is truncated. There is a closing bracket at the bottom of the list. So it's dictionaries within a list.)
"positions": [
{
"dw_nominate": "0.466",
"member_id": "A000055",
"vote_position": "Yes"
},
{
"dw_nominate": "0.995",
"member_id": "A000367",
"vote_position": "Yes"
},
{
"dw_nominate": "0.666",
"member_id": "A000369",
"vote_position": "Yes"
},
Output from print data2['member_id'], output is the same if using 'positions', 'vote_position', etc.:
Traceback (most recent call last):
File "/Users/Owner/PycharmProjects/untitled2/1", line 9, in <module>
print data2["positions"]
TypeError: string indices must be integers, not str
Output from print data:
u'positions': [{u'dw_nominate': u'0.466', u'vote_position': u'Yes', u'member_id': u'A000055'}, {u'dw_nominate': u'0.995', u'vote_position': u'Yes', u'member_id': u'A000367'}, {u'dw_nominate': u'0.666', u'vote_position': u'Yes', u'member_id': u'A000369'}
Output from print data['positions']:

KeyError: 'positions'
Output from print.data(keys):

I just want to print the list of "member_id" numbers.
So you need to loop over positions and access the member_id in each dict:
data ={"positions": [
{
"dw_nominate": "0.466",
"member_id": "A000055",
"vote_position": "Yes"
},
{
"dw_nominate": "0.995",
"member_id": "A000367",
"vote_position": "Yes"
},
{
"dw_nominate": "0.666",
"member_id": "A000369",
"vote_position": "Yes"
}]}
print([d["member_id"] for d in data["results"]["positions"]])
['A000055', 'A000367', 'A000369']
If you look at the API documentation there are examples of each json response.
data2 is a string value, it doesn't have keys. I think what you want to print is data["positions"]
That's a weird output from data, you don't even have the braces. Try printing the type(data), it should be dict
So I should change the heading of this to Scrapping JSON for XML in Python. I'm sure not everyone else would have the same issues I did with JSON but after many frustrating hours I decided to go down path #2... the xml version. The xml version was much easier to work with right out of the gate. In about 1/10 the time I got what I was looking for.
from urllib2 import urlopen
from xml.dom import minidom
feed = urlopen("http://api.nytimes.com/svc/politics/v3/us/legislative.xml?
doc = minidom.parse(feed)
id_element = doc.getElementsByTagName("member_id")
id_number0 = id_element[0].childNodes[0].nodeValue #just a sample
id_number1 = id_element[1].childNodes[0].nodeValue #just a sample
id_number2 = id_element[2].childNodes[0].nodeValue #just a sample
print len(id_element) #to see how many items were in the variable
count = 0
for item in id_element:
print id_element[count].childNodes[0].nodeValue
count = count + 1
if count == 434:
break
This is definitely not the cleanest loop. I'm still working on that. But the code solves the problem that I had originally posted. The API key is not the actual one, formatting in the answer window was throwing it off so I just erased a bunch of it. You can find the API at the NYT developer website.
Thanks to everyone who posted.
