Hello, i have the same problem:

Sorry I am a beginner programmer and I am wondering where to insert the .wav file and if this will play the file or just loop it

Do I have to insert the file AND my local file path here?

def run(self):
# Open Wave File and start play!
wf = wave.open(self.filepath, 'rb')
player = pyaudio.PyAudio()

I tried different options but nothing is working..

@leamu no you have to use it outside the class like this:

import os
import wave
import threading
import sys

# PyAudio Library
import pyaudio

class WavePlayerLoop(threading.Thread):
    CHUNK = 1024

    def __init__(self, filepath, loop=True):
        """
        Initialize `WavePlayerLoop` class.
        PARAM:
            -- filepath (String) : File Path to wave file.
            -- loop (boolean)    : True if you want loop playback.
                                   False otherwise.
        """
        super(WavePlayerLoop, self).__init__()
        self.filepath = os.path.abspath(filepath)
        self.loop = loop

    def run(self):
        # Open Wave File and start play!
        wf = wave.open(self.filepath, 'rb')
        player = pyaudio.PyAudio()

        # Open Output Stream (based on PyAudio tutorial)
        stream = player.open(format=player.get_format_from_width(wf.getsampwidth()),
                             channels=wf.getnchannels(),
                             rate=wf.getframerate(),
                             output=True)

        # PLAYBACK LOOP
        data = wf.readframes(self.CHUNK)
        while self.loop:

                wf.rewind()

player.play()

I also wanted to ask that, how can we play all the songs from a particular folder, in python because as a beginner I'm facing a problem with that,

currently, I'm using the code -

elif 'play some music' in query:
music_dir = 'D:\Music'
songs = os.listdir(music_dir)
print(songs)
os.startfile(os.path.join(music_dir, songs[0]))

But this only plays the 1st song, [0]

if anyone knows - how to play all the songs then, please help,

thanks
