JSONDecodeError when iterating twitter data - json

Question

I'm trying to iterate twitter data which is stored in a json file:
fname = 'test.json'
with open(fname, 'r') as f:
for line in f:
tweet = json.loads(line)['text']
print(tweet)
It prints the first tweet in the file just fine but when it iterates for a second time it gives me a JSONDecodeError:
JSONDecodeError: Expecting value: line 2 column 1 (char 1)
My JSON file is 650Mb is size approximately.
To get the twitter data I used the StreamListener from the Twitter API.
Here is a glimpse into my JSON file:

How can I solve this issue?

Answer 1

If your JSON file has exactly the same structure as the piece you are posting, the empty lines between tweets indeed cause a JSONDecodeError. If that's the problem, just check that the line is not empty before processing:
In [12]:
with open(fname, 'r') as f:
for line in f:
if (not line.strip()):
continue
tweet = json.loads(line)['text']
print(tweet)
Hope it helps.
