8 # c = Cdplayer(r.gettrackinfo()) |
| 883 | 9 # |
| 10 # Now you can use c.artist, c.title and c.track[trackno] (where trackno | |
| 11 # starts at 1). When the CD is not recognized, all values will be the empty | |
| 12 # string. | |
| 13 # It is also possible to set the above mentioned variables to new values. | |
| 14 # You can then use c.write() to write out the changed values to the | |
| 15 # .cdplayerrc file. | |
