I want to extract "SNG_TITLE" and "ART_NAME" values from the code in "script" tag using BeautifulSoup in Python. (the whole script is too long to paste)

<script>window.__DZR_APP_STATE__ = {"TAB":{"loved":{"data":[{"SNG_ID":"126884459","PRODUCT_TRACK_ID":"360276641","UPLOAD_ID":0,"SNG_TITLE":"Heathens","ART_ID":"647650","PROVIDER_ID":"3","ART_NAME":"Twenty One Pilots","ARTISTS":[{"ART_ID":"647650","ROLE_ID":"0","ARTISTS_SONGS_ORDER":"1","ART_NAME":"Twenty One Pilots","ART_PICTURE":"259dcf52853363d79753ec301377645d","SMARTRADIO":"1","RANK":"487762","LOCALES":[],"__TYPE__":"artist"}],"ALB_ID":"13371165","ALB_TITLE":"Heathens","TYPE":0,"MD5_ORIGIN":"5cea723b83af1ff0a62d65d334b978d4","VIDEO":false,"DURATION":"195","ALB_PICTURE":"3dfc8c9e406cf1bba8ce0695a44a9b7e","ART_PICTURE":"259dcf52853363d79753ec301377645d","RANK_SNG":"967143","SMARTRADIO":"1","FILESIZE_AAC_64":0,"FILESIZE_MP3_64":"0","FILESIZE_MP3_128":"3135946","FILESIZE_MP3_256":0,"FILESIZE_MP3_320":"7839868","FILESIZE_FLAC":"21777150","FILESIZE":"3135946","GAIN":"-12","MEDIA_VERSION":"4","DISK_NUMBER":"1","TRACK_NUMBER":"1","VERSION":"","EXPLICIT_LYRICS":"0","RIGHTS":{"STREAM_ADS_AVAILABLE":true,"STREAM_ADS":"2000-01-01","STREAM_SUB_AVAILABLE":true,"STREAM_SUB":"2000-01-01"},"ISRC":"USAT21601930","DATE_ADD":1497886149,"HIERARCHICAL_TITLE":"","SNG_CONTRIBUTORS":{"mainartist":["Twenty One Pilots"],"engineer":["Adam Hawkins"],"mixer":["Adam Hawkins"],"masterer":["Chris Gehringer"],"drums":["Josh Dun"],"producer":["Mike Elizondo","Tyler Joseph"],"programmer":["Mike Elizondo","Tyler Joseph"],"vocals":["Tyler Joseph"],"writer":["Tyler Joseph"]},"LYRICS_ID":30553991,"__TYPE__":"song"},{"SNG_ID":"99976952","PRODUCT_TRACK_ID":"171067651","UPLOAD_ID":0,"SNG_TITLE":"Stressed Out","ART_ID":"647650","PROVIDER_ID":"3","ART_NAME":"Twenty One Pilots","ARTISTS":[{"ART_ID":"647650","ROLE_ID":"0","ARTISTS_SONGS_ORDER":"1","ART_NAME":"Twenty One Pilots", ...</script>

The idea of the code is to print out the user name, all song and artist names that can be found on the given page. 

import requests
from bs4 import BeautifulSoup

base_url = 'https://www.deezer.com/en/profile/1589856782/loved'

r = requests.get(base_url)

soup = BeautifulSoup(r.text, 'html.parser')

user_name = soup.find(class_='user-name')
print(user_name.text)

This prints the user name.

for script in soup.find_all('script'):
    print(script.contents)

If I understand correctly, the script I need is a dictionary, so I just need to find it and get its contents. The problem is I don't know how to specifically find exactly this "script". It doesn't have any attributes or anything that makes it unique. So I tried a loop that finds all scripts on the page and prints out their contents, but not sure how to proceed further.

How do I find only this particular "script" on the page? Can I access the values in a different way?

Scripts don't change places in code so you can count them and use index to get correct script.

all_scripts[6]

Script is normal string so you can also use standard string functions ie.

if '{"loved"' in script.text:

Code with both methods - I use [:100] to display only part of string.

import requests
from bs4 import BeautifulSoup

base_url = 'https://www.deezer.com/en/profile/1589856782/loved'

r = requests.get(base_url)

soup = BeautifulSoup(r.text, 'html.parser')

all_scripts = soup.find_all('script')

print('--- first method ---')
print(all_scripts[6].text[:100])

print('--- second method ---')
for number, script in enumerate(all_scripts):
    if '{"loved"' in script.text:
        print(number, script.text[:100])

Result:

--- first method ---
window.__DZR_APP_STATE__ = {"TAB":{"loved":{"data":[{"SNG_ID":"126884459","PRODUCT_TRACK_ID":"360276
--- second method ---
6 window.__DZR_APP_STATE__ = {"TAB":{"loved":{"data":[{"SNG_ID":"126884459","PRODUCT_TRACK_ID":"360276

EDIT: When you have correct script then you can use slicing to get only JSON string and use module json to convert it to python dictionary and then tou can get data

import requests
from bs4 import BeautifulSoup
import json

base_url = 'https://www.deezer.com/en/profile/1589856782/loved'

r = requests.get(base_url)

soup = BeautifulSoup(r.text, 'html.parser')

all_scripts = soup.find_all('script')

data = json.loads(all_scripts[6].get_text()[27:])

print('key:', data.keys())
print('key:', data['TAB'].keys())
print('key:', data['DATA'].keys())
print('---')

for item in data['TAB']['loved']['data']:
    print('ART_NAME:', item['ART_NAME'])
    print('SNG_TITLE:', item['SNG_TITLE'])
    print('---')

Result:

key: dict_keys(['TAB', 'DATA'])
key: dict_keys(['loved'])
key: dict_keys(['USER', 'FOLLOW', 'FOLLOWING', 'HAS_BLOCKED', 'IS_BLOCKED', 'IS_PUBLIC', 'CURATOR', 'IS_PERSONNAL', 'NB_FOLLOWER', 'NB_FOLLOWING'])
