Я довольно новичок в python, и я обнаруживаю эмоции музыки, используя spotify api, но когда я передаю значения словаря в html, он ничего не печатает. тогда как я могу печатать в командной строке,
Когда я пишу {{энергия}}
Ничего не печатается при доступе к localhost: 8000 // emotion
Это моя функция в views.py
def emotion(request):

artist = 'pawan singh'
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, client_secret=client_secret)
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
sp.trace=False
search_querry = title+ ' ' + artist
result = sp.search(search_querry)
for i in result['tracks']['items']:
# Find a songh that matches title and artist
if (i['artists'][0]['name'] == artist) and (i['name'] == title):
print (i['uri'])
break
else:
try:
# Just take the first song returned by the search (might be named differently)
print (result['tracks']['items'][0]['uri'])
uri = result['tracks']['items'][0]['uri']
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, client_secret=client_secret)

sp.trace=False
features = sp.audio_features(uri)
data = {
'energy' : features[0]['energy'],

}
print(features[0]['energy']) # Prints successfully 0.862
except:
data = { 'error' : 'NO SONGS FOUND' }
return render(request, 'emotion_view.html', data)
Это мой emotion_view.html в шаблонах
{{ energy }}
А в emotion_view.html ничего не печатает, что с ним не так
