Help trying to extract some data

In my file, I have

from mutagen.id3 import ID3
tags = ID3(mp3_file)

Now if I do print(tags.keys())

It informs me that there's a TXXX:FMPS_Rating_Amarok_Score

But when I attempt to print(tags["TXXX:FMPS_Rating_Amarok_Score"])

It says there's a KeyError. What am I doing wrong?

  • This is strange. I tried your snippet with your file and it works for me:

    (env) โžœ  testing cat x.py
    from mutagen.id3 import ID3
    tags = ID3("myfile.mp3")
    print(tags["TXXX:FMPS_Rating_Amarok_Score"])

    • I'm getting 0.66 when I do get a rating. But I'm definitely not getting that to print. Here's the full file

      import os

          tags = ID3(mp3_file)
      
          print(tags["TXXX:FMPS_Rating_AMarok_Score"]) #Gives KeyError
      
          for frame in tags.getall("TXXX"):
            rating = frame #This is terrible. The last key is the rating and since I can't call it by the key, I'm just refilling the variable
            print(rating)

              mp3_file = "/".join([folderpath, filename])
              rating = extract_rating(mp3_file)
              print(mp3_file, rating, sep= "_____")
              print(rating)
      #
      #        # Implement logic to find the track ID on Navidrome based on filename or other metadata
      #        track_id = find_track_id_on_navidrome(filename)  # Replace with your implementation#
      #
      #        if track_id:
      #            update_rating_on_navidrome(track_id, rating)
      #        else:
      #            print(f"Track ID not found on Navidrome for {filename}")
      

      Have I called something erroneously that would mess it up?

      Sorry if it's terrible to read, up until I started trying to do this, I had never touched Python before and haven't attempted to code for years.

      • Dict keys are case sensitive in python. In your code I can see the key you've used has a capital M in Amarok. Maybe that's the issue here
