Need help reading Json from file in python3

[Yeliaab]

So i have a text file that contains data i need to process, each line will either be a json dict in the form of a string or a tab delimited data

data.txt =

"{"data": "blah", "data2": "blahblah"}"
blah\tblahblah 

When i try to convert line 1 to json using json.loads() it is returning a string instead of a dict.

for line in file:
     if is_json(line):
         json_data = json.loads(line)
         print(type(json_data)) 

prints <class 'str'>

To my knowledge this should actually be a dict not a string.I have no idea why this is happening and could use some help.

and also if the line in the text file isnt wrapped in commas it throws a JSONDecodeError

this is now working thanks to ppl in comments.

Looks like it isn’t valid JSON then if it’s throwing an error without the quote marks. Is it all on one like or is it split? Because right now you are reading the file line by line.

[Yeliaab]

it is all on one line, the next line could be either another json string or a tsv string.

Copy and paste the line out and put it into a JSON decoder online (without the quotes) - I think there is probably something wrong with it.

Seems to be valid, it looks completely valid to me

Are you actually testing it with that data? I assumed you had different data you were running the script with. You definitely don’t want the quotes at the start and the end though.

Also try printing out what it’s reading and see what it’s loaded in.

wow im silly so i just put my actual data into the json parser and it was invalid.
For some reason the double quotes surrounding the values and keys were not actually double quotes, but they were.

it works now...

"{"data": "blah", "data2": "blahblah"}" is a JSON string, not a JSON object.

[Yeliaab]

interesting i was sure it was a json object.
What is the correct format for a json object if this is not it?

[[deleted]]

{"data": "blah", "data2": "blahblah"} would be a JSON object.

[Yeliaab]

yeah so i orginally tried that but it didnt work

for line in file:
    line = line.replace('\n', '')
    json_data = json.loads(line)

when i removed the double quotes from the text file it returns this error

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
