I'm trying to access some data within nested ordered dictionaries. This dictionary was created by using the XMLTODICT module. Obviously I would like to create my own dictionaries but this one is out of my control.
I've tried to access them numerous ways.
Example:
Using a for loop:
I can access the first level using v["name"] which gives me Child_Policy and Parent Policy
When I do v["class"]["name"] I would expect to get "Test1" but that's not the case.
I've also tried v[("class", )] variations as well with no luck.
Any input would be much appreciated
The data below is retrieved from a device via XML and converted to dictionary with XMLTODICT.
[
{
"#xmlns": "http://cisco.com/ns/yang/Cisco-IOS-XE-policy",
"name": "Child_Policy",
"class": [
{
"name": "Test1",
"action-list": {
"action-type": "bandwidth",
"bandwidth": {
"percent": "30"
}
}
},
{
"name": "Test2",
"action-list": {
"action-type": "bandwidth",
"bandwidth": {
"percent": "30"
}
}
}
]
},
{
"#xmlns": "http://cisco.com/ns/yang/Cisco-IOS-XE-policy",
"name": "Parent_Policy",
"class": {
"name": "class-default",
"action-list": [
{
"action-type": "shape",
"shape": {
"average": {
"bit-rate": "10000000"
}
}
},
{
"action-type": "service-policy",
"service-policy": "Child_Policy"
}
]
}
}
]
My expectations result is to retrieve values from the nested dictionary and produce and output similar to this:
Queue_1: Test1
Action_1: bandwidth
Allocation_1: 40
Queue_2: Test2
Action_2: bandwidth
Allocation_2: 10
I have now issue formatting the output, just getting the values is the issue.
#
I had some time tonight so I changed the code be be dynamic:
int = 0
int_2 = 0
for v in policy_dict.values():
print("\n")
print("{:15} {:<35}".format("Policy: ", v[0]["name"]))
print("_______")
for i in v:
int_2 = int_2 + 1
try:
print("\n")
print("{:15} {:<35}".format("Queue_%s: " % int_2, v[0]["class"][int]["name"]))
print("{:15} {:<35}".format("Action_%s: " % int_2, v[0]["class"][int]["action-list"]["action-type"]))
print("{:15} {:<35}".format("Allocation_%s: " % int_2, v[0]["class"][int]["action-list"]["bandwidth"]["percent"]))
int = int + 1
except KeyError:
break
pass
According to the sample you posted you can try to retrieve values like:
v[0]["class"][0]["name"]
This outputs:
Test1

So I'm new to graphQL and I've been figuring out the Uniswap API, through the sandbox browser, but I'm running this program which just gets metadata on the top 100 tokens and their relative pools, but the pool one isn't working at all. I'm trying to put two conditions of if token0's hash is this and token1's hash is this, it should output the pool of those two, however if only outputs pools with the token0 hash, and just ignores the second one. I've tried using and, _and, or two where's seperated by {} or , so on so forth. This is an example I have (python btw):
class ExchangePools:
def QueryPoolDB(self, hash1, hash2):
query = """
{
pools(where: {token0: "%s"}, where: {token1:"%s"}, first: 1, orderBy:volumeUSD, orderDirection:desc) {
id
token0 {
id
symbol
}
token1 {
id
symbol
}
token1Price
}
}""" % (hash1, hash2)
return query
or in the sandbox explorer this:
{
pools(where: {token0: "0x2260fac5e5542a773aa44fbcfedf7c193bc2c599"} and: {token1:"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"}, first: 1, orderBy:volumeUSD, orderDirection:desc) {
id
token0 {
id
symbol
}
token1 {
id
symbol
}
token1Price
}
}
with this output:
{
"data": {
"pools": [
{
"id": "0x4585fe77225b41b697c938b018e2ac67ac5a20c0",
"token0": {
"id": "0x2260fac5e5542a773aa44fbcfedf7c193bc2c599",
"symbol": "WBTC"
},
"token1": {
"id": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",
"symbol": "WETH"
},
"token1Price": "14.8094450357546760737720184457113"
}
]
}
}
How can I get the API to register both statements?
JSON OUTPUT:
${response}= [
{
"Name":"7122Project",
"checkBy":[
{
"keyId":"NA",
"target":"1232"
}
],
"Enabled":false,
"aceess":"123"
},
{
"Name":"7122Project",
"checkBy":[
{
"keyId":"_GU6S3",
"target":"123"
}
],
"aceess":"11222",
"Enabled":false
},
{
"Name":"7122Project",
"checkBy":[
{
"keyId":"-1lLUy",
"target":"e123"
}
],
"aceess":"123"
}
]
Need to get the keyId values from json without using hardcoded index using robot?
I did
${ID}= set variable ${response[0]['checkBy'][0]['keyId']}
But I need to check the length get all keyID values and store the values that dose not contain NA
How can I do check length and use for loop using robot framework?
I suppose you can have more elements in checkBy arrays, like so:
response = [
{
"Name":"7122Project",
"checkBy": [
{
"keyId": "NA",
"target": "1232"
}
],
"Enabled": False,
"aceess": "123"
},
{
"Name": "7122Project",
"checkBy": [
{
"keyId": "_GUO6g6S3",
"target": "123"
}
],
"aceess": "11222",
"Enabled": False
},
{
"Name": "7122Project",
"checkBy": [
{
"keyId": "-1lLlZOUy",
"target": "e123"
},
{
"keyId": "test",
"target": "e123"
}
],
"aceess": "123"
}
]
then you can key all keyIds in Python with this code:
def get_key_ids(response):
checkbys = [x["checkBy"] for x in response]
key_ids = []
for check_by in checkbys:
for key_id in check_by:
key_ids.append(key_id["keyId"])
return key_ids
for the example above, it will return: ['NA', '_GUO6g6S3', '-1lLlZOUy', 'test_NA'].
You want to get both ids with NA and without NA, so perhaps you can change the function a bit:
def get_key_ids(response, predicate):
checkbys = [x["checkBy"] for x in response]
key_ids = []
for check_by in checkbys:
for key_id in check_by:
if predicate(key_id["keyId"]):
key_ids.append(key_id["keyId"])
return key_ids
and use it like so:
get_key_ids(response, lambda id: id == "NA") # ['NA']
get_key_ids(response, lambda id: id != "NA") # ['_GUO6g6S3', '-1lLlZOUy', 'test_NA']
get_key_ids(response, lambda id: "NA" in id) # ['NA', 'test_NA']
get_key_ids(response, lambda id: "NA" not in id) # ['_GUO6g6S3', '-1lLlZOUy']
Now it's just a matter of creating a library and importing it into RF. You can get inspiration in the official documentation.
But I need to check the length get all keyID values and store the values that dose not contain NA
I don't completely understand what you are up to. Do you mean length of keyId strings, like "NA" and its length of 2, or the number of keyIds in the response?
How can I do check length and use for loop using robot framework?
You can use keyword Should Be Equal * from BuiltIn library. Some examples of for loops could be found in the user guide here.
Now you should have all the parts you need to accomplish your task, you can try to put it all together.
So, I need some help returning an ID having found a certain string. My JSON looks something like this:
{
"id": "id1"
"field1": {
"subfield1": {
"subrield2": {
"subfield3": {
"subfield4": [
"string1",
"string2",
"string3"
]
}
}
}
}
"id": "id2"
"field1": {
"subfield1": {
"subrield2": {
"subfield3": {
"subfield4": [
"string4",
"string5",
"string6"
]
}
}
}
}
}
Now, I need to get the ID from a certain string, for example:
For "string5" I need to return "id2"
For "string2" I need to return "id1"
In order to find these strings I have used objectpath python module like this: json_Tree.execute('$..subfield4'))
After doing an analysis on a huge amount of strings, I need to return the ones that are meeting my criterias. I have the strings that I need (for example "string3"), but now I have to return the IDs.
Thank you!!
Note: I don't have a lot of experience with coding, I just started a few months ago to work on a project in Python and I have been stuck on this for a while
Making some assumptions about the actual structure of the data as being:
[
{
"id": "id1",
"subfield1": {
"subfield2": {
"subfield3": {
"subfield4": [
"string1",
"string2",
"string3"
]
}
}
}
}
// And so on
]
And assuming that each string1, string2 etc. is in only one id, then you can construct this mapping like so:
data: List[dict] # The json parsed as a list of dicts
string_to_id_mapping = {}
for record in data:
for string in record["subfield1"]["subfield2"]["subfield3"]["subfield4"]:
string_to_id_mapping[string] = record["id"]
assert string_to_id_mapping["string3"] == "id1"
If each string can appear in multiple ids then the following will catch all of them:
from collections import defaultdict
data: List[dict] # The json parsed as a list of dicts
string_to_id_mapping = defaultdict(set)
for record in data:
for string in record["subfield1"]["subfield2"]["subfield3"]["subfield4"]:
string_to_id_mapping[string].add(record["id"])
assert string_to_id_mapping["string3"] == {"id1"}
Is there any way to pull the key from JSON if the only thing I know is the value? (In groovy or python)
An example:
I know the "_number" value and I need a key.
So let's say, known _number is 2 and as an output, I should get dsf34f43f34f34f
{
"id": "8e37ecadf4908f79d58080e6ddbc",
"project": "some_project",
"branch": "master",
"current_revision": "3rtgfgdfg2fdsf",
"revisions": {
"43g5g534534rf34f43f": {
"_number": 3,
"created": "2019-04-16 09:03:07.459000000",
"uploader": {
"_account_id": 4
},
"description": "Rebase"
},
"dsf34f43f34f34f": {
"_number": 2,
"created": "2019-04-02 10:54:14.682000000",
"uploader": {
"_account_id": 2
},
"description": "Rebase"
}
}
}
With Groovy:
def json = new groovy.json.JsonSlurper().parse("x.json" as File)
println(json.revisions.findResult{ it.value._number==2 ? it.key : null })
// => dsf34f43f34f34f
Python 3: (assuming that data is saved in data.json):
import json
with open('data.json') as f:
json_data = json.load(f)
for rev, revdata in json_data['revisions'].items():
if revdata['_number'] == 2:
print(rev)
Prints all revs where _number equals 2.
using dict-comprehension:
print({k for k,v in d['revisions'].items() if v.get('_number') == 2})
OUTPUT:
{'dsf34f43f34f34f'}
My json file look likes this and I'm trying to access the element syslog in a for loop.

I do it like this:

I'm new to python (and json as well). Could anybody suggest where I'm going wrong ?
You are looping over the values in the list referenced by data['execution'], not indices.
Just use those values (dictionaries) directly:
for i in data['execution']:
cmd = i['test_case']['scriptname']
You probably want to give that a more meaningful loop name:
for entry in data['execution']:
cmd = entry['test_case']['scriptname']
you can try this, it works for me
dataArray=data['execution']
for i in range(len(dataArray)):
cmd = dataArray[i]['test_case']['scriptname']
This exactly loops by indices, so there will not be any confusion,
For me this is very simple and understandable
