How to get Track Duration for Spotify using Spotipy

Question

I've been playing around with Spotify API in Python (Spotipy) and I don't know how to get the duration of the track I'm currently playing on Spotify. I'm assuming it would look something like this:

global spotifyObject
trackInfo = spotifyObject.current_user_playing_track()

// would probably look something like this?
trackInfo['duration']

I suppose it would be a dictionary because trackInfo['currently_playing_type'] == 'ad' worked successfully. After taking some time searching through the Spotipy documentation and guessing a few keywords, I still did not hit the bullseye.

In Android Java Spotify API, it was actually pretty straight forward:

mSpotifyAppRemote.getPlayerApi()
            .subscribeToPlayerState()
            .setEventCallback(playerState -> {
                final Track track = playerState.track;
                String trackName = track.name;
                // here!
                Long trackDuration = track.duration;
                });

Any help is appreciated :)

Thank you!

it says `trackInfo['duration_ms']` throws a `KeyError: 'duration_ms'` when i print it out — Kelvin Jou, Jul 24 '21 at 06:47
That's what it said ^ Your suggestion is missing`['item']` before accessing the nested items in the dictionary — Kelvin Jou, Jul 29 '21 at 01:33

current_user_playing_track gets in response a json like this:

{
  [...] # [...] means i've deleted a portion to keep the code short
  "progress_ms": 5465,
  "item": {
    "album": [...]
    "artists": [...]
    "disc_number": 1,
    "duration_ms": 163294,
    "explicit": false
    },
  },
  "currently_playing_type": "track",
  "actions": {
    "disallows": {
      "pausing": true,
      "skipping_prev": true
    }
  },
  "is_playing": false
}

as we can see "duration_ms" is inside "item", so to access it you need to do

trackInfo['item']["duration_ms"]

The spotify developer console might be helpful for cases like this: https://developer.spotify.com/console/get-users-currently-playing-track/
