Python Error: Cannot extract data from dictionary - python-3.x

Question

I have a json output (y) like this below.
{
"WebACL":{
"Name":"aBlockKnownBadInputs-WebAcl",
"Id":"4312a5d0-9878-4feb-a083-09d7a9cfcfbb",
"ARN":"arn:aws:wafv2:us-east-1:100467320728:regional/webacl/aBlockKnownBadInputs-WebAcl/4312a5d0-9878-4feb-a083-09d7a9cfcfbb",
"DefaultAction":{
"Allow":{
}
},
"Description":"",
"Rules":[
{
"Name":"AWS-AWSManagedRulesKnownBadInputsRuleSet",
"Priority":500,
"Statement":{
"ManagedRuleGroupStatement":{
"VendorName":"AWS",
"Name":"AWSManagedRulesKnownBadInputsRuleSet"
}
},
"OverrideAction":{
"None":{
}
},
"VisibilityConfig":{
"SampledRequestsEnabled":true,
"CloudWatchMetricsEnabled":true,
"MetricName":"AWS-AWSManagedRulesKnownBadInputsRuleSet"
}
}
]
}
}
I want to extract "AWS-AWSManagedRulesKnownBadInputsRuleSet" from the section:-
"Name":"AWS-AWSManagedRulesKnownBadInputsRuleSet",
"Priority":500,
"Statement":{
"ManagedRuleGroupStatement":{
"VendorName":"AWS",
"Name":"AWSManagedRulesKnownBadInputsRuleSet"*
At the minute my code is returning a key error:
KeyError: 'Rules[].Statement[].ManagedRuleGroupStatement[].Name'
The format of this line is clearly wrong, but I don't know why.
ruleset = y['Rules[].Statement[].ManagedRuleGroupStatement[].Name']
My code block:
respons = client.get_web_acl(Name=(acl),Scope='REGIONAL',Id=(ids))
for y in response['WebACLs']:
ruleset = y['Rules[].Statement[].ManagedRuleGroupStatement[].Name']
Does anyone know what I'm doing wrong here?

Answer 1

UPDATE :- In case anyone else comes up against this problem, I fixed this by doing it a slightly different way.
#Requesting the info from AWS via get_web_acl request
respons = client.get_web_acl(Name=(acl),Scope='REGIONAL',Id=(ids))
#Converting the dict output to a string to make it searchable
result = json.dumps(respons)
#Defining what I want to search for
fullstring = "AWS-AWSManagedRulesKnownBadInputsRuleSet"
#Searching the output & printing the result: if = true / else = false
if fullstring in result:
print("Found WAF ruleset: AWS-AWSManagedRulesKnownBadInputsRuleSet!")
else:
print("WAF ruleset not found!")

Also, as part of my research I found a cool thing called jello.
(https://github.com/kellyjonbrazil/jello).
jello is similar to jq in that it processes JSON and JSON Lines data except it uses standard python dict and list syntax.
So, I copied my json into a file called file.json
Ran cat file.json | jello -s to print a grep-able schema by using the -s option
Found the bit I was interested in - in my case the name of the ManagedRuleGroupStatement and ran the following:
cat file.json | jello -s _.WebACL.Rules[0].Statement.ManagedRuleGroupStatement.Name
This gave me exactly what I wanted!
It doesn't work inside a python script but was something new and interesting to learn!
