I keep getting the following error trying to parse json in python "string indices must be integers"

Question

When I use json.loads I get the following error

string indices must be integers

I was doing some research and saw someone with what I thought was a similar situation. I changed this

json.dumps(newstring_two)

to this

json.loads(json.dumps(newstring_two))

but it still did not work. Here is the function I created

def panties():
        pan_url = 'http://www.panvideos.com'
        html = requests.get(pan_url, headers=headers)
        soup = BeautifulSoup(html.text, 'html5lib')
        video_row = soup.find_all('div', {'class': 'video'})

        def youtube_link(url):
            youtube_page = requests.get(url, headers=headers)
            soupdata = BeautifulSoup(youtube_page.text, 'html5lib')
            video_row = soupdata.find('div', {'class': 'video-player'})
            entries = [{'text': str(div),
                        } for div in video_row][3]['text']

            oldstring = str(entries)
            removed = '<script type="text/javascript">jwplayer("video-setup").setup('
            newstring = oldstring.replace(removed, "")
            removed_two = ');</script>'
            newstring_two = newstring.replace(removed_two, "")
            parsed_json = json.dumps(newstring_two)
            finishe = parsed_json['file']

            return finishe

        entries = [{'text': div.h4.text,
                    'href': div.a.get('href'),
                    'tube': youtube_link(div.a.get('href')),
                    } for div in video_row][:1]

        return entries

but it's not working. What's the issue?

json.dumps() returns a string. You can't index a string by a key name as you are doing in finishe = parsed_json['file']. — John Gordon

Also, the variable name parsed_json makes me think that you've gotten json.dumps and json.loads confused. — John Gordon

@JohnGordon the variable parsed_json initially used json.loads, but I was getting an error that was talking about double quotes. I saw in hitchhikers guide to python that json.dumps changes the single quotes to double quotes. Json is strict about the quotes — losee

'newstring_two' is string, so parsed_json = json.dumps(newstring_two) should be replaced parsed_json = json.loads(newstring_two). see JSON encoder and decoder

when I do what you mentioned and do this parsed_json['file'] I get the following error message "Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"

newstring_two is not standard json string. If you just get file field，you can use re. for example tube_file = re.search('file:"(.*?)",', new_string_two) print(tube_file.group(1))

You should use a integer instead of 'file' statement at that line:

finishe = parsed_json['file']

So, it can be so:

finishe = parsed_json[0]

The 0 number at example can be 1,2,3,4 ..... You must find out which is the true number.

Thanks for responding but that doesn't work. Doing that only returns a single character. The output of doing that would be "{"

try that: str = "" for i in parsed_json: str+=i print str what do you see when you do it ?
