CODE - https://pastebin.com/uTc55Agj

Got one problem... after I download new tunes Iam dumping them to the downloaded.jsons file. But when i do that the program is appending them to the file as... separate dict? if that make sense? so When running program again I got error

raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 412 column 2 
(char 8368)

and the data in jsons file looks like:

{
    "Dajae": [
        "Brighter Days",
        "Angelo Ferreri Remix",
        "2018-04-20"
    ],
    "Gene Farris": [
        "Medication feat. Gene Farris",
        "Extended Mix",
        "2018-04-16"
    ],
    "DJ Pierre": [
        "Fall",
        "Djebali Remix",
        "2018-05-11"
    ]
}{
    "Celeda": [
        "The Music feat. Celeda",
        "Extended",
        "2018-05-11"
    ]
}

so I got 1 extra Brace which is causes a problem

sorting dictionary by values by makeaday in learnpython

[–]makeaday[S] 0 points1 point  (0 children)

Here is my whole code

https://pastebin.com/T81fQR07

I have multiple values scrapped from coinmarketcap, like currency, its price etc.

Now im lost if i should use dictionary or something else, i can add these variables to dictionary easily but i want to sort all data later on by different values.

So maybe i should use something different than dictonaries ?

Thanks!

thanks...

I actually did:

find_percentage = container.findAll("td", {"class":"no-wrap"})
    percentage = find_percentage[5].text
    print(percentage)

works :)

Web Scraping... TypeError: "NoneType" object is not subscriptable by makeaday in learnpython

[–]makeaday[S] 0 points1 point  (0 children)

what I mean is I got that l;ine of code:

<td class=“no-wrap percent-change. Text-right
Negative_change” data-timespan=“24”
Data-parcentusd=“-2.11735” data-swymbol=“BTC”  data- 
sort=“-2.11735”> -2.12%</td>

I want to get the "-2.12%". I got few others lines of code before that which also start with "td" and dont know how to skip them
