This is my json file input.
{"Report":{"id":101,"type":"typeA","Replist":[{"rptid":"r001","subrpt":{"subid":74,"subname":"name1","subval":113},"RelsubList":[{"Relid":8,"Relsubdetails":{"Rel_subname":"name8","Rel_Subval":65}},{"Relid":5,"Relsubdetails":{"Rel_subname":"name5","Rel_Subval":40}}],"fldA":30,"fldB":23}]}}
...
I am writing python program to convert the input into the below format in my dictionary.
I am new to python.
Expected output:
out: {"id": "101", "type": "typeA", "rptid": "r001", "subrpt_subid": "74", "subrpt_subname": "name1", "subrpt_subval":"113","Relid":"8","Rel_subname":"name8","Rel_Subval":"65","Relid":"5","Rel_subname":"name5","Rel_Subval":"40","fldA":"30","fldB":"23"
I used the following logic to convert the output till subrpt.
Current output:
out: {'id': '101', 'type': 'typeA', 'rptid': 'r001', 'subrpt_subid': '74', 'subrpt_subname': 'name1', 'subrpt_subval': '113'}
But I am struggling to get the logic of RelsubList(it looks like it has both list and dictionary[{}] ).
please help me to get the logic for the same.
import json
list1 = []
dict1 = {}
dict2 = {}
data_file = "samp1.json"
file = open(data_file)
for line in file:
json_line = json.loads(line)
json_line = json_line["Report"]
dict1["id"]=str(json_line["id"])
dict1["type"] = str(json_line["type"])
json_line = json_line["Replist"]
dict1["rptid"]= str(json_line[0]["rptid"])
dict1["subrpt_subid"] = str(json_line[0]["subrpt"]["subid"])
dict1["subrpt_subname"] = str(json_line[0]["subrpt"]["subname"])
dict1["subrpt_subval"] = str(json_line[0]["subrpt"]["subval"])
print("out:", dict1)
Some of your logic is confusing to me, i.e. why are you doing json.loads(line) in every loop?
Anyway, the following should get you the logic for RealsubList:
import json
f = open("data.json")
data = json.load(f)
for line in data:
relsublist = data["Report"]["Replist"][0]["RelsubList"]
print(relsublist)
Results in:
[{'Relid': 8, 'Relsubdetails': {'Rel_subname': 'name8', 'Rel_Subval': 65}}, {'Relid': 5, 'Relsubdetails': {'Rel_subname': 'name5', 'Rel_Subval': 40}}]
The reason for the [0] index after ["Replist"] is Replist contains an array of nested dictionaries, so you need to call it out by index. In this case its only a single array, so it would be 0

How can I extract the T3 Period, Year and maximum value?
file.json
[
{"Fecha":"2022-08-01T00:00:00.000+02:00", "T3_TipoDato":"Avance", "T3_Periodo":"M08", "Anyo":2022, "value":10.4},
{"Fecha":"2022-07-01T00:00:00.000+02:00", "T3_TipoDato":"Definitivo", "T3_Periodo":"M07", "Anyo":2022, "value":10.8},
{"Fecha":"2022-06-01T00:00:00.000+02:00", "T3_TipoDato":"Definitivo", "T3_Periodo":"M06", "Anyo":2022, "value":10.2}
]
My code:
import json
with open("file.json") as f:
distros_dict = json.load(f)
print (distros_dict)
that is my proposition.
Load data from a file to a list.
Loop thru every dict in a list to edit it.
(At my example I, deleted two keys from every dict in list.)
import json
distros_dict = []
with open(f'file.json', "r", encoding='utf-8') as f:
distros_dict.extend(json.load(f))
for item in distros_dict:
item.pop('Fecha')
item.pop('T3_TipoDato')
distros_dict = sorted(distros_dict, key = lambda i: i['value'], reverse=True)[0]
Try this:
from json import load
with open("file.json") as f:
dictionary_max = max(load(f), key=lambda x: x["value"])
result = {
"T3_Periodo": dictionary_max["T3_Periodo"],
"Anyo": dictionary_max["Anyo"],
"value": dictionary_max["value"],
}
print(result)
output:
{'T3_Periodo': 'M07', 'Anyo': 2022, 'value': 10.8}
I have produced a couple of json files after scraping a few elements. The structure for each file is as follows:
us.json
{'Pres': 'Biden', 'Vice': 'Harris', 'Secretary': 'Blinken'}
uk.json
{'1st Min': 'Johnson', 'Queen':'Elizabeth', 'Prince': 'Charles'}
I'd like to know how I could edit the structure of each dictionary inside the json file to get an output as it follows:
[
{"title": "Pres",
"name": "Biden"}
,
{"title": "Vice",
"name": "Harris"}
,
{"title": "Secretary",
"name": "Blinken"}
]
As far as I am able to think how to do it (I'm a beginner, studying only since a few weeks) I need first to run a loop to open each file, then I should generate a list of dictionaries and finally modify the dictionary to change the structure. This is what I got NOT WORKING as it overrides always with the same keys.
import os
import json
list_of_dicts = []
for filename in os.listdir("DOCS/Countries Data"):
with open(os.path.join("DOCS/Countries Data", filename), 'r', encoding='utf-8') as f:
text = f.read()
country_json = json.loads(text)
list_of_dicts.append(country_json)
for country in list_of_dicts:
newdict = country
lastdict = {}
for key in newdict:
lastdict = {'Title': key}
for value in newdict.values():
lastdict['Name'] = value
print(lastdict)
Extra bonus if you could also show me how to generate an ID mumber for each entry. Thank you very much
This look like task for list comprehension, I would do it following way
import json
us = '{"Pres": "Biden", "Vice": "Harris", "Secretary": "Blinken"}'
data = json.loads(us)
us2 = [{"title":k,"name":v} for k,v in data.items()]
us2json = json.dumps(us2)
print(us2json)
output
[{"title": "Pres", "name": "Biden"}, {"title": "Vice", "name": "Harris"}, {"title": "Secretary", "name": "Blinken"}]
data is dict, .items() provide key-value pairs, which I unpack into k and v (see tuple unpacking).
You can do this easily by writing a simple function like below
import uuid
def format_dict(data: dict):
return [dict(title=title, name=name, id=str(uuid.uuid4())) for title, name in data.items()]
where you can split the items as different objects and add a identifier for each using uuid.
Full code can be modified like this
import uuid
import os
import json
def format_dict(data: dict):
return [dict(title=title, name=name, id=str(uuid.uuid4())) for title, name in data.items()]
list_of_dicts = []
for filename in os.listdir("DOCS/Countries Data"):
with open(os.path.join("DOCS/Countries Data", filename), 'r', encoding='utf-8') as f:
country_json = json.load(f)
list_of_dicts.append(format_dict(country_json))
# list_of_dicts contains all file contents
The following code is giving me the error:

item_list.append(item['SellerSKU'])
#print(item)
#print(id_list)
#print(data1)
#print(item_list)
time.sleep(10)
I don't understand why Python thinks this is a list and not a dictionary. When I print id_list it looks like a dictionary (curly braces, single quotes, colons, etc)
print(data1) shows my dictionary
{
'ListOrderItemsResponse':{
'#xmlns':'https://mws.amazonservices.com/Orders/201 3-09-01',
'ListOrderItemsResult':{
'OrderItems':{
'OrderItem':{
'QuantityOrdered ':'1',
'Title':'Delta Rothko Rolling Bicycle Stand',
'ConditionId':'New',
'Is Gift':'false',
'ASIN':'B00XXXXTIK',
'SellerSKU':'9934638',
'OrderItemId':'49 624373726506',
'ProductInfo':{
'NumberOfItems':'1'
},
'QuantityShipped':'0',
'C onditionSubtypeId':'New'
}
},
'AmazonOrderId':'112-9XXXXXX-XXXXXXX'
},
'ResponseM etadata':{
'RequestId':'8XXXXX8-0866-44a4-96f5-XXXXXXXXXXXX'
}
}
}
Any ideas?
because you are iterating over each key value in dict:
{'QuantityOrdered ': '1', 'Title': 'Delta Rothko Rolling Bicycle Stand', 'ConditionId': 'New', 'Is Gift': 'false', 'ASIN': 'B00XXXXTIK', 'SellerSKU': '9934638', 'OrderItemId': '49 624373726506', 'ProductInfo': {'NumberOfItems': '1'}, 'QuantityShipped': '0', 'C onditionSubtypeId': 'New'}
so first value in item will be 'QuantityOrdered ' and you are trying to access this string as if it is dictionary
you can just do:
id_list.append(data1['ListOrderItemsResponse']['ListOrderItemsResult']['OrderItems']['OrderItem']['SellerSKU']))
and avoid for loop in dictionary
I guess you are trying to iterate OrderItems and finding their SellerSKU values.
for item in data1['ListOrderItemsResponse']['ListOrderItemsResult']['OrderItems']:
item_list.append(item['SellerSKU'])
I want to convert a file to json.
The file has the format:
Temp=24.0* Humidity=41.0% Date=02/01/17-20:37
Temp=24.0* Humidity=42.0% Date=02/01/17-20:38
Temp=24.0* Humidity=42.0% Date=02/01/17-20:39
I'm using the following code:
list = {}
with open("record.txt") as f:
for line in f:
if not ("Failed" in line):
lists = line.split(" ")
for l in lists:
ll = dict([l.split("=")])
// print(json.dumps(ll))
list.update(ll)
And when I print the dictionary created i get.
>>> print (list)
{'Temp': '29.0*', 'Humidity': '31.0%', 'Date': '15/07/17-10:56\n', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00Temp': '21.0*'}
I don't understand why. Does anyone knows why i don't get the entire dictionary?
Before converting to json i will also separate to sub-dictionary's by new line /n. Is this possible?
Your input file contains the same set of unique keys three times so a corresponding representation in Python, which can then be serialised to JSON, is an array of dictionaries.
Try this change to your code:
list = []
with open("record.txt") as f:
for line in f:
if not ("Failed" in line):
lists = line.rstrip().split(" ")
ll = {}
for l in lists:
k,v = l.split("=")
ll[k] = v
list.append(ll)
If you then do:
print list
You should get:
print list
[{'Date': '02/01/17-20:37', 'Temp': '24.0*', 'Humidity': '41.0%'}, {'Date': '02/01/17-20:38', 'Temp': '24.0*', 'Humidity': '42.0%'}, {'Date': '02/01/17-20:39', 'Temp': '24.0*', 'Humidity': '42.0%'}]
You can then dump to JSON with:
import json
json.dumps(list)
'[{"Date": "02/01/17-20:37", "Temp": "24.0*", "Humidity": "41.0%"}, {"Date": "02/01/17-20:38", "Temp": "24.0*", "Humidity": "42.0%"}, {"Date": "02/01/17-20:39", "Temp": "24.0*", "Humidity": "42.0%"}]'
You can create a list of dictionaries like this and then can do whatever modification you want to do.
list = {}
complete_list=[]
with open("record.txt") as f:
for line in f:
if not ("Failed" in line):
lists = line.split(" ")
lists[-1] = lists[-1].strip() #it should remove the \n at the end.
for l in lists:
ll = dict([l.split("=")])
// print(json.dumps(ll))
list.update(ll)
complete_list.append(list)
I am new to JSON and Python,I am trying to achieve below
Need to parse below JSON
{
"id": "12345abc",
"codes": [
"BSVN1FKW3JKKNNMN",
"HJYYUKJJL999OJR",
"DFTTHJJJJ0099JUU",
"FGUUKHKJHJGJJYGJ"
],
"ctr": {
"source": "xyz",
"user_id": "1234"
}
}
Expected output:Normalized on "codes" value
ID~CODES~USER_ID
12345abc~BSVN1FKW3JKKNNMN~1234
12345abc~HJYYUKJJL999OJR~1234
12345abc~DFTTHJJJJ0099JUU~1234
12345abc~FGUUKHKJHJGJJYGJ~1234
Started with below ,but need help to get to my desired output.
The "codes" block can have n number of values separated by comma.
The below code is throwing an error "TypeError: string indices must be integers"
#!/usr/bin/python
import os
import json
import csv
f = open('rspns.csv','w')
writer = csv.writer(f,delimiter = '~')
headers = [‘ID’,’CODES’,’USER_ID’]
default = ''
writer.writerow(headers)
string = open('sample.json').read().decode('utf-8')
json_obj = json.loads(string)
#print json_obj['id']
#print json_obj['codes']
#print json_obj['codes'][0]
#print json_obj['codes'][1]
#print json_obj['codes’][2]
#print json_obj['codes’][3]
#print json_obj['ctr’][‘user_id']
for keyword in json_obj:
row = []
row.append(str(keyword['id']))
row.append(str(keyword['codes']))
row.append(str(keyword['ctr’][‘user_id']))
writer.writerow(row)
If your json_obj looks exactly like that , that is it is a dictionary, then the issue is that when you do -
for keyword in json_obj:
You are iterating over keys in json_obj, then if you try to access ['id'] for that key it should error out saying string indices must be integers .
You should first get the id and user_id before looping and then loop over json_obj['codes'] and then add the previously computed id and user_id along with the current value from codes list to the writer csv as a row.
Example -
import json
import csv
string = open('sample.json').read().decode('utf-8')
json_obj = json.loads(string)
with open('rspns.csv','w') as f:
writer = csv.writer(f,delimiter = '~')
headers = ['ID','CODES','USER_ID']
writer.writerow(headers)
id = json_obj['id']
user_id = json_obj['ctr']['user_id']
for code in json_obj['codes']:
writer.writerow([id,code,user_id])
You don't want to iterate through json_obj as that is a dictionary and iterating through will get the keys. The TypeError is caused by trying to index into the keys ('id', 'code', and 'ctr') -- which are strings -- as if they were a dictionary.
Instead, you want a separate row for each code in json_obj['codes'] and to use the json_obj dictionary for your lookups:
for code in json_obj['codes']:
row = []
row.append(json_obj['id'])
row.append(code)
row.append(json_obj['ctr’][‘user_id'])
writer.writerow(row)
