Hi all, above is the format of each chunk of data in my first.txt file. I would like to read it and change it to to the json format like the one below, and store it to second.txt file.

def convert_to_json(path, name, username, post, link, replies, retweets, likes, retweetby, date, domainname):
with open(path, 'a') as file:
    stringData = [{"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}]

    objData = json.load(stringData)
    file.write(stringData)

The above code was suppose to take in data and then append it to second.txt file. However, my code did not manage to append the data i want into my second.txt file. No apparent error was shown at the console, and i seek suggestions and help from all of the experts here.

Answer 1

You are not using json.load correctly; try it like this:

record = {"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}  

with open(path, 'a') as file:
    objData = json.load(file)
    objData.append(record)
    file.write(json.dumps(objData))

Answer 2

1. Try json.dumps instead of load
2. Why do you wrap you dict in a list?

3. Write to file the result of the json.dumps, not the object

    with open(path, 'a+') as file: stringData = {"ContentUrl": link, "Text": post, "PublishDate": date.strip(), "Title": "", "SourceUrl": domainname, "SocialNetwork": media, "Source": "", "Author": name, "Like_count": likes.strip(), "Replies_count": replies.strip(), "Retweets_count": retweets.strip(), "Schema": "SOCIAL_MEDIA"} objData = json.dumps(stringData) file.write(objData) 

Answer 3

Add all the data to the list ( stringData ) and finally write the stringData to the second file using

stringData = [] #init

def addToDataToBeWritten(path, name, username, post, link, replies, retweets, likes, retweetby, date, domainname):    

    row = {"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}
    stringData.append(raw)

''' Read and call the method here'''
with open(path, 'w') as file:  
    file.write(json.dumps(stringData))
