i'm having trouble with a simple question.
a = {
"apiVersion": "2.1",
"data": {
"startIndex": 1,
"items": [{
"id": "YVA3UoZM0zU",
"title": "Trailer - Lisbela eo Prisioneiro"
}]
}
}
i don't know how to get the info id.
this is a string.
so, i tried to make this
import simplejson as json
>>> type(js)
<type 'dict'>
js = json.loads(a)
print js['data'{'items'[{'id'}]}]
>>> syntax error
this syntax is invalid, how could I get this info? it's supposed to be easy. where I'm making wrong?
Try:
js['data']['items'][0]['id']
It would appear that there may be multiple items in this structure. If you'd like to extract all item ids as a list, the following will do it:
[item['id'] for item in js['data']['items']]

I have a .json file with many entries looking like this:
{
"name": "abc",
"time": "20220607T190731.442",
"id": "123",
"relatedIds": [
{
"id": "456",
"source": "sourceA"
},
{
"id": "789",
"source": "sourceB"
}
],
}
I am saving each entry in a python object, however, I only need the related ID from source A. Problem is, the related ID from source A is not always first place in that nested list.
So data['relatedIds'][0]['id'] is not reliable to yield the right Id.
Currently I am solving the issue like this:
import json
with open("filepath", 'r') as file:
data = json.load(file)
for value in data['relatedIds']:
if(value['source'] == 'sourceA'):
id_from_a = value['id']
entry = Entry(data['name'], data['time'], data['id'], id_from_a)
I don't think this approach is the optimal solution though, especially if relatedIds list gets longer and more entries appended to the JSON file.
Is there a more sophisticated way of singling out this 'id' value from a specified source without looping through all entries in that nested list?
For a cleaner solution, you could try using python's filter() function with a simple lambda:
import json
with open("filepath", 'r') as file:
data = json.load(file)
filtered_data = filter(lambda a : a["source"] == "sourceA", data["relatedIds"])
id_from_a = next(filtered_data)['id']
entry = Entry(data['name'], data['time'], data['id'], id_from_a)
Correct me if I misunderstand how your json file looks, but it seems to work for me.
One step at a time, in order to get to all entries:
>>> data["relatedIds"]
[{'id': '789', 'source': 'sourceB'}, {'id': '456', 'source': 'sourceA'}]
Next, in order to get only those entries with source=sourceA:
>>> [e for e in data["relatedIds"] if e["source"] == "sourceA"]
[{'id': '456', 'source': 'sourceA'}]
Now, since you don't want the whole entry, but just the ID, we can go a little further:
>>> [e["id"] for e in data["relatedIds"] if e["source"] == "sourceA"]
['456']
From there, just grab the first ID:
>>> [e["id"] for e in data["relatedIds"] if e["source"] == "sourceA"][0]
'456'
Can you get whatever generates your .json file to produce the relatedIds as an object rather than a list?
{
"name": "abc",
"time": "20220607T190731.442",
"id": "123",
"relatedIds": {
"sourceA": "456",
"sourceB": "789"
}
}
If not, I'd say you're stuck looping through the list until you find what you're looking for.
I've searched and there's a similar problem here but the solution states to fix the json. I really cant fix the json produced as its from a REST API.

},
"entries": [
{
"SI_ID": 31543,
"SI_NAME": "Some Client",
"SI_PARENTID": 31414,
"SI_PATH": {
"SI_FOLDER_NAME1": "COR OPS",
"SI_FOLDER_ID1": 31414,
"SI_FOLDER_OBTYPE1": 1,
"SI_FOLDER_NAME2": "CLIENT",
"SI_FOLDER_ID2": 28178,
"SI_FOLDER_OBTYPE2": 1,
"SI_NUM_FOLDERS": 2
}
}
]
}
I need to be able to get the folder names from SI_PATH, but that is where I am having issues. I can access "entries" fine as the whole json is considered as a dict, but the problem is after. If I get "entries", its just a list with a len of 1
import json
data = json.load(open('file.json'))
print(type(data))
print(data['entries])
print(type(data['entries']))
Sample output below:
<class 'dict'>
<class 'list'>
[{'SI_ID': 31543, 'SI_NAME': 'Some Client', 'SI_PARENTID': 31414, 'SI_PATH': {'SI_FOLDER_NAME1': 'COR OPS', 'SI_FOLDER_ID1': 31414, 'SI_FOLDER_OBTYPE1': 1, 'SI_FOLDER_NAME2': 'CLIENT', 'SI_FOLDER_ID2': 28178, 'SI_FOLDER_OBTYPE2': 1, 'SI_NUM_FOLDERS': 2}}]
I can use pandas to put the 'entries' onto a DataFrame and pull in the SI_PATH values, but not sure how to access each of them.
f = pd.DataFrame(data['entries'])
print(f['SI_PATH'].values)
Output of this:
[{'SI_FOLDER_NAME1': 'COR OPS', 'SI_FOLDER_ID1': 31414, 'SI_FOLDER_OBTYPE1': 1, 'SI_FOLDER_NAME2': 'CLIENT', 'SI_FOLDER_ID2': 28178, 'SI_FOLDER_OBTYPE2': 1, 'SI_NUM_FOLDERS': 2}]
But unsure as to how to access the items individual from this point. If possible, really want to stick with just importing json.
Since there is only one item in the list that is data['entries']:
print(data['entries'][0]['SI_ID'])
Prints:
31543
since it is a list of dict, why not
for items in data['entries']:
print(items.get("SI_ID"))
I have the following JSON data:
x = df.to_json(orient='records')
print(x)
[{"val":"3760","id":"204","quantity":2},{"val":"8221","id":"220","quantity":8}]
I want to add the data to my REST call, but it results in the following string in the payload (note: the single quotes around the square bracket:
'updateVals': '[{"val":"3760","id":"204","quantity":2},{"val":"8221","id":"220","quantity":8}]'}}
The fact that the JASON values are listed as one big string, the REST call results in an HTTP 400 error.
The code is:
url = 'my_url'
payload = {
'client_id': 'my_id',
'api_key': 'my_key',
"data": {
"uuid": "myUUID",
"timeStamp": "2018-09-12T06:17:48+00:00",
"updateVals": x
}
}
How do I plug the JSON into the REST call? I assume I have to split the string, or maybe there is a more straightforward answer?
Still not sure what you need, JSON is really one big string:
x = [{"val":"3760","id":"204","quantity":2},
{"val":"8221","id":"220","quantity":8}]
>>> json.dumps(x)
>>> '[{"val": "3760", "id": "204", "quantity": 2}, {"val": "8221", "id": "220", "quantity": 8}]'
Can some one tell me what I am doing wrong ?I am Getting this error..

You are not converting the text to json. Try
data = json.loads(res.text)
or
data = res.json()
Apart from that, you probably need to change the for loop to loop over the values instead of the keys. Change it to something the following
for recipe in data['recipes'].values()
There are two problems with your code, which you could have found out by yourself by doing a very minimal amount of debugging.
The first problem is that you don't parse the response contents from json to a native Python object. Here:
data = res.text
data is a string (json formatted, but still a string). You need to parse it to turn it into it's python representation (in this case a dict). You can do it using the stdlib's json.loads() (general solution) or, since you're using python-requests, just by calling the Response.json() method:
data = res.json()
Then you have this:
for recipe in data['recipes']:
# ...
Now that we have turned data into a proper dict, we can access the data['recipes'] subdict, but iterating directly over a dict actually iterates over the keys, not the values, so in your above for loop recipe will be a string ( "47635", "65568" etc). If you want to iterate over the values, you have to ask for it explicitly:
for recipe in data['recipes'].values():
# now `recipe` is the dict you expected
What am I missing when trying to parse this JSON output with Python? The JSON looks like this:
{
"start": 0,
"terms": [
"process_name:egagent.exe"
],
"highlights": [],
"total_results": 448,
"filtered": {},
"facets": {},
"results": [
{
"username": "SYSTEM",
"alert_type": "test"
},
{
"username": "SYSTEM2",
"alert_type": "test"
}
]
}
The Python I'm trying to use to access this is simple. I want to grab username, but everything I try throws an error. When it doesn't throw an error, I seem to get the letter of each one. So, if I do:
apirequest = requests.get(requesturl, headers=headers, verify=False)
readable = json.loads(apirequest.content)
#print readable
for i in readable:
print (i[0])
I get s, t, h, t, f, f, r, which are the first letters of each item. If I try i[1], I get the second letter of each item. When I try by name, say, i["start"], I get an error saying the string indices must be integers. I'm pretty confused and I am new to Python, but I haven't found anything on this yet. Please help! I just want to access the username fields, which is why I am trying to do the for loop. Thanks in advance!
Try this:
for i in readable["results"]:
print i["username"]
Load your json string:
import json
s = """
{
"start": 0,
"terms": [
"process_name:egagent.exe"
],
"highlights": [],
"total_results": 448,
"filtered": {},
"facets": {},
"results": [
{
"username": "SYSTEM",
"alert_type": "test"
},
{
"username": "SYSTEM2",
"alert_type": "test"
}
]
}
"""
And print username for every result:
print [res['username'] for res in json.loads(s)['results']]
Output:
[u'SYSTEM', u'SYSTEM2']
for i in readable will iterate i through each key in the readable dictionary. If you then print i[0], you are printing the first character of each key.
Given that you want the values associated with the "username" key in the entries of the list which is associated with the "results" key, you can get them like this:
for result in readable["results"]:
print (result["username"])
If readable is your JSON object (dict), you can access elements like you'd in every map, using their keys.
readable["results"][0]["username"]
Should give you "SYSTEM" string as result.
To print every username, do:
for result in readable["results"]:
print(result["username"])
If your JSON is a str object, you have to deserialize it with json.loads(readable) first.
