当python文件与声音文件位于不同的目录中时，如何播放声音？

Question

So I'm making a text-based game, and after completion, I want to compile the end product to a .exe format so it's fairly easy to share (I plan on using cx_freeze) Now, I wanted to add some background music for the game, the code below works fine IF AND ONLY IF the python file is on the desktop and so is the "sound.wav" I'm looking for ways to execute the sound.wav in background whether it's on the same or different directory as the python file, thanks

import winsound
winsound.PlaySound('sound.wav', winsound.SND_FILENAME)

Answer 1

Use os package to generate absolute path to your music file to make sure it always works fine.

For exampe, if your project's structure is

root
    src
        your_python_file.py
    assets
        sound.wav

So you can generate the absolute path to the sound.wav by

import os
# __file__ means the path of the current python script
root_dir = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))
bg_path = os.path.join(root_dir, "assets", "sound.wav")

Answer 2

Lets say you have a sub-folder called foo and a second sub-folder called subfoo

If you want go into foo sub-folder use foo/sound.wav if you want to go in the second sub-folder subfoo use foo/subfoo/sound.wav .

If you want to go up a dictionary you can use ./ . For example if your sound is located in foo and you script in subfoo it could be accessed with ./sound.wav to go up one by one file use ./ again.

Otherwise you can use an 'absolute' file path where you start from C: or the drive you wish to access. For example if your file filename was located in Desktop you could use:

C:/users/username/Desktop/foo/subfoo/sound.wav
