I need to get the 'ids' of this json response,the thing is that, there are many dictionaries with a list of dictionaries inside,how can I do this??(PS:len(items) is 20,so I need to get the 20 ids in the form of a dictionary.
{'playlists': {'href': 'https://api.spotify.com/v1/search?query=rewind-The%25&type=playlist&offset=0&limit=20',

Im trying to get it through this:
dict={'id':''}
for playlists in playlist_data['playlists']:
for items in playlists['items']:
for item in items:
for dic in range(len(item)):
for id in dic['id']:
dict.update('id')
print(dict)
I get this error:
TypeError: string indices must be integers ```
Try something like this:
ids = [item["id"] for item in json_data["playlists"]["items"]]
This is called a list comprehension.
You want to iterate over all of the "items" within the "playlists" key.
You can access that list of items:
json_data["playlists"]["items"]
Then you iterate over each item within items:
for item in json_data["playlists"]["items"]
Then you access the "id" of each item:
item["id"]
You can index an object using the keys of object. I can see there are two places where id is present in an object. To retrieve those two ids and store them in a dictionary format, you can use the following approach -
_json = {
'playlists': {
'href': 'https://api.spotify.com/v1/search?query=rewind-The%25&type=playlist&offset=0&limit=20',
'items': [{
'collaborative': False,
'description': 'Remember what you listened to in 2010? Rewind and rediscover your favorites.',
'external_urls': {
'spotify': 'https://open.spotify.com/playlist/37i9dQZF1DXc6IFF23C9jj'
},
'href': 'https://api.spotify.com/v1/playlists/37i9dQZF1DXc6IFF23C9jj',

'images': [{

'width': None
}],
'name': 'Rewind - The Sound of 2010',
'owner': {
'display_name': 'Spotify',
'external_urls': {
'spotify': 'https://open.spotify.com/user/spotify'
},
'href': 'https://api.spotify.com/v1/users/spotify',
'id': 'spotify',
'type': 'user',
'uri': 'spotify:user:spotify'
},
'primary_color': None,
'public': None,
'snapshot_id': 'MTU5NTUzMTE1OSwwMDAwMDAwMGQ0MWQ4Y2Q5OGYwMGIyMDRlOTgwMDk5OGVjZjg0Mjdl',
'tracks': {
'href': 'https://api.spotify.com/v1/playlists/37i9dQZF1DXc6IFF23C9jj/tracks',
'total': 100
},
'type': 'playlist',
'uri': 'spotify:playlist:37i9dQZF1DXc6IFF23C9jj'
}, ]
}
}
res_dict = {'id':[items['id'], items['owner']['id']] for items in _json['playlists']['items']}
print(res_dict)
OUTPUT :
{'id': ['37i9dQZF1DXc6IFF23C9jj', 'spotify']}
If you don't need the second id that's present in the json object, you can just remove it from above res_dict and modify it as -
res_dict = {'id':items['id'] for items in _json['playlists']['items']}
This will only fetch the id present in the items array as key of any element and not any further nested ids (like items[i]->owner->id won't be in the final res as it was in the fist case ).

I have a problem. I want to save a dict. But unfortunately I got the following error - TypeError: expected bytes, list found. I want to save my my_dict as netCDF. How could I save my dict? I looked at https://docs.xarray.dev/en/stable/user-guide/io.html , Saving Python dictionary to netCDF4 file and some other links and blogs
from netCDF4 import Dataset
my_dict = {

I have tried everything I can possible come up with, but the value wont go away.
I have a JSON user and if user['permissions'] have key permission = "DELETE PAGE" remove that index of del user['permissions'][1] (in this example)
I want to have a list of possible values as "DELETE PAGE" and so on. If value in key, then delete that index.
Then return the users json without those items found.
I have tried del user['permission][x] and .pop() and so on but it is still there.
{
'id': 123,
'name': 'My name',
'description': 'This is who I am',
'permissions': [{
'id': 18814,
'holder': {
'type': 'role',
'parameter': '321',
'projectRole': {
'name': 'Admin',
'id': 1,
}
},
'permission': 'VIEW PAGE'
}, {
'id': 18815,
'holder': {
'type': 'role',
'parameter': '123',
'projectRole': {
'name': 'Moderator',
'id': 2
}
},
'permission': 'DELETE PAGE'
}]
}
Here's the code:
perm = a['permissions']
for p in perm:
if p['permission'] == 'DELETE PAGE':
perm.remove(p)
print(a)
Output:
{'id': 123, 'name': 'My name', 'description': 'This is who I am', 'permissions': [{'id': 18814, 'holder': {'type': 'role', 'parameter': '321', 'projectRole': {'name': 'Admin', 'id': 1}}, 'permission': 'VIEW PAGE'}]}
Stack on this case, Python steamlit select box menu returns string, but I need dict or list, to use it further in my code.
I want to see company1, company2, company3 in dropdown menu, and if user's choice was for example 'company2' get ['ID': 'zxc222’, 'NAME': 'company2','DESC': 'comp2'].
BaseObject = [{
'ID': 'zxc123',
'NAME': 'company1',
'DESC': 'comp1'
}, {
'ID': 'zxc222',
'NAME': 'company2',
'DESC': 'comp2'
}, {
'ID': 'zxc345',
'NAME': 'company3',
'DESC': 'comp3'
}]
lenbo = len(BaseObject)
options = []
for i in range(0, lenbo):
options.append((BaseObject[i])['NAME'])
st.selectbox('Subdivision:', options)
You can do the conversion to a dict after the selectbox:
import streamlit as st
BaseObject = [{
'ID': 'zxc123',
'NAME': 'company1',
'DESC': 'comp1'
}, {
'ID': 'zxc222',
'NAME': 'company2',
'DESC': 'comp2'
}, {
'ID': 'zxc345',
'NAME': 'company3',
'DESC': 'comp3'
}]
lenbo = len(BaseObject)
options = []
for i in range(0, lenbo):
options.append((BaseObject[i])['NAME'])
choice = st.selectbox('Subdivision:', options)
chosen_base_object = None
for base_object in BaseObject:
if base_object["NAME"] == choice:
chosen_base_object = dict(base_object)
print(chosen_base_object) # {'ID': 'zxc345', 'NAME': 'company3', 'DESC': 'comp3'}
This is my first question :)
I loop over a nested dictionary to print specific values. I am using the following code.
for i in lizzo_top_tracks['tracks']:
print('Track Name: ' + i['name'])
It works for string variables, but does not work for other variables. For example, when I use the following code for the date variable:
for i in lizzo_top_tracks['tracks']:
print('Album Release Date: ' + i['release_date'])
I receive a message like this KeyError: 'release_date'
What should I do?
Here is a sample of my nested dictionary:
{'tracks': [{'album': {'album_type': 'album',
'artists': [{'external_urls': {'spotify': 'https://open.spotify.com/artist/56oDRnqbIiwx4mymNEv7dS'},
'href': 'https://api.spotify.com/v1/artists/56oDRnqbIiwx4mymNEv7dS',
'id': '56oDRnqbIiwx4mymNEv7dS',
'name': 'Lizzo',
'type': 'artist',
'uri': 'spotify:artist:56oDRnqbIiwx4mymNEv7dS'}],
'external_urls': {'spotify': 'https://open.spotify.com/album/74gSdSHe71q7urGWMMn3qB'},
'href': 'https://api.spotify.com/v1/albums/74gSdSHe71q7urGWMMn3qB',
'id': '74gSdSHe71q7urGWMMn3qB',
'images': [{'height': 640,
'width': 640}],
'name': 'Cuz I Love You (Deluxe)',
'release_date': '2019-05-03',
'release_date_precision': 'day',
'total_tracks': 14,
'type': 'album',
'uri': 'spotify:album:74gSdSHe71q7urGWMMn3qB'}]}
The code you posted isn't syntactically correct; running it through a Python interpreter gives a syntax error on the last line. It looks like you lost a curly brace somewhere toward the end. :)
I went through it and fixed up the white space to make the structure easier to see; the way you had it formatted made it hard to see which keys were at which level of nesting, but with consistent indentation it becomes much clearer:
lizzo_top_tracks = {
'tracks': [{
'album': {
'album_type': 'album',
'artists': [{
'external_urls': {
'spotify': 'https://open.spotify.com/artist/56oDRnqbIiwx4mymNEv7dS'
},
'href': 'https://api.spotify.com/v1/artists/56oDRnqbIiwx4mymNEv7dS',
'id': '56oDRnqbIiwx4mymNEv7dS',
'name': 'Lizzo',
'type': 'artist',
'uri': 'spotify:artist:56oDRnqbIiwx4mymNEv7dS'
}],
'external_urls': {
'spotify': 'https://open.spotify.com/album/74gSdSHe71q7urGWMMn3qB'
},
'href': 'https://api.spotify.com/v1/albums/74gSdSHe71q7urGWMMn3qB',
'id': '74gSdSHe71q7urGWMMn3qB',
'images': [{'height': 640, 'width': 640}],
'name': 'Cuz I Love You (Deluxe)',
'release_date': '2019-05-03',
'release_date_precision': 'day',
'total_tracks': 14,
'type': 'album',
'uri': 'spotify:album:74gSdSHe71q7urGWMMn3qB'
}
}]
}
So the first (and only) value you get for i in lizzo_top_tracks['tracks'] is going to be this dictionary:
i = {
'album': {
'album_type': 'album',
'artists': [{
'external_urls': {
'spotify': 'https://open.spotify.com/artist/56oDRnqbIiwx4mymNEv7dS'
},
'href': 'https://api.spotify.com/v1/artists/56oDRnqbIiwx4mymNEv7dS',
'id': '56oDRnqbIiwx4mymNEv7dS',
'name': 'Lizzo',
'type': 'artist',
'uri': 'spotify:artist:56oDRnqbIiwx4mymNEv7dS'
}],
'external_urls': {
'spotify': 'https://open.spotify.com/album/74gSdSHe71q7urGWMMn3qB'
},
'href': 'https://api.spotify.com/v1/albums/74gSdSHe71q7urGWMMn3qB',
'id': '74gSdSHe71q7urGWMMn3qB',
'images': [{'height': 640, 'width': 640}],
'name': 'Cuz I Love You (Deluxe)',
'release_date': '2019-05-03',
'release_date_precision': 'day',
'total_tracks': 14,
'type': 'album',
'uri': 'spotify:album:74gSdSHe71q7urGWMMn3qB'
}
}
The only key in this dictionary is 'album', the value of which is another dictionary that contains all the other information. If you want to print, say, the album release date and a list of the artists' names, you'd do:
for track in lizzo_top_tracks['tracks']:
print('Album Release Date: ' + track['album']['release_date'])
print('Artists: ' + str([artist['name'] for artist in track['album']['artists']]))
If these are dictionaries that you're building yourself, you might want to remove some of the nesting layers where there's only a single key, since they just make it harder to navigate the structure without giving you any additional information. For example:
lizzo_top_albums = [{
'album_type': 'album',
'artists': [{
'external_urls': {
'spotify': 'https://open.spotify.com/artist/56oDRnqbIiwx4mymNEv7dS'
},
'href': 'https://api.spotify.com/v1/artists/56oDRnqbIiwx4mymNEv7dS',
'id': '56oDRnqbIiwx4mymNEv7dS',
'name': 'Lizzo',
'type': 'artist',
'uri': 'spotify:artist:56oDRnqbIiwx4mymNEv7dS'
}],
'external_urls': {
'spotify': 'https://open.spotify.com/album/74gSdSHe71q7urGWMMn3qB'
},
'href': 'https://api.spotify.com/v1/albums/74gSdSHe71q7urGWMMn3qB',
'id': '74gSdSHe71q7urGWMMn3qB',
'images': [{'height': 640, 'width': 640}],
'name': 'Cuz I Love You (Deluxe)',
'release_date': '2019-05-03',
'release_date_precision': 'day',
'total_tracks': 14,
'type': 'album',
'uri': 'spotify:album:74gSdSHe71q7urGWMMn3qB'
}]
This structure allows you to write the query the way you were originally trying to do it:
for album in lizzo_top_albums:
print('Album Release Date: ' + album['release_date'])
print('Artists: ' + str([artist['name'] for artist in album['artists']]))
Much simpler, right? :)

At least I hope this is a dictionary. Honestly at this point I've gotten so many errors I'm not too sure. Here's the code in question:
playlist_api_endpoint = "{}/playlists".format(profile_data["href"])
playlists_response = requests.get(playlist_api_endpoint,
headers=authorization_header)
playlist_data = json.loads(playlists_response.text)
display_arr = [profile_data] + playlist_data["items"]
return render_template("index.html",sorted_array=display_arr)
Basically I want to be able to filter out the last uri object and any other uri objects when adding new playlists. I've tried .items(), filtered dictionary, and a couple of other things I can't remember. If anyone has an idea of where I'm going wrong or how to to achieve my goal, I'd love some help. Thanks!
