Yes, the issue you're encountering in the Python script is related to how Python interprets string literals, particularly the backslash (\) character. In Python, the backslash is used as an escape character, which means it gives special meaning to the character that follows it. For example, \n is interpreted as a newline character, not as a backslash followed by the letter 'n'.

In your Python script, when you use the path D:\Music\NateKingCole\Unforgettable.mp3, Python is trying to interpret \N as an escape sequence, but since \N is not a valid escape sequence, it results in a "malformed \N character escape" error.

To fix this issue, you have a couple of options:

1. Double Backslashes: Use double backslashes (\\) to escape the backslash itself, so Python treats it as a literal backslash character in the file path.

   Audio.playAudioFile("D:\\Music\\NateKingCole\\Unforgettable.mp3");
   

2. Raw String Notation: Prefix the string with r to tell Python to treat the string as a raw string, which means escape sequences (like \n) will not be processed. Instead, every character is treated as a literal character.

   Audio.playAudioFile(r"D:\Music\NateKingCole\Unforgettable.mp3");
   

3. Forward Slashes: Replace backslashes with forward slashes (/). Python on Windows can handle forward slashes in file paths.

   Audio.playAudioFile("D:/Music/NateKingCole/Unforgettable.mp3");
   

Any of these solutions should resolve the error you're encountering with the Python script in your ARC project.

All three of your answers worked with a small correction.

You wrote:

Audio.playAudioFile and it should be Audio.PlayAudioFile

Hopefully someone else might find this question useful in the future

Thank you for pointing out the correction, and I'm glad to hear that the solutions worked for you! You're absolutely right, the correct method to use in ARC's Python scripting for playing an audio file is Audio.PlayAudioFile(). My apologies for the oversight. Here's the corrected usage with the proper method name:

1. Double Backslashes:

Audio.PlayAudioFile("D:\\Music\\NateKingCole\\Unforgettable.mp3");

2. Raw String Notation:

Audio.PlayAudioFile(r"D:\Music\NateKingCole\Unforgettable.mp3");

3. Forward Slashes:

Audio.PlayAudioFile("D:/Music/NateKingCole/Unforgettable.mp3");

Thank you for sharing this question, and indeed, it could be very helpful for others facing similar issues with file paths in Python scripts within ARC. If you have any more questions or need further assistance, feel free to ask!
