當我在Python中播放WAV時，程序在文件結束時不會停止，程序沒有響應

Question

因此，我們的任務是編寫一個播放用戶歌曲的短程序，然後讓他們猜測該歌曲的流派，之後該節目詢問他們是否想聽另一首歌曲或者是否想要退出。 我遇到的問題是程序首次播放歌曲時。它首先打印測驗的標題，並詢問用戶是否想要聽歌，或通過輸入「-1」退出測驗。但是，如果用戶選擇播放歌曲，則會播放歌曲，但一旦剪輯結束，它就不會繼續到測驗的下一部分（猜測流派）。該程序只是停留在這個「播放」模式，我什麼也做不了，進入cntrl + C吧。

我已經無情地搜尋了這個問題的答案，我已經寫出了更簡單的程序來看看它是否會繼續播放歌曲，甚至問我的講師關於這個問題（他沒有任何答案對我來說很奇怪）。 這裏是我的代碼（playWav2是用於播放wav文件的pyaudio腳本）：

import playWav2 as pw 
#Here I am providing the list of genres and songs for the program to take info from. 
#I am using "s" for the song list, and "i" for the genre list. 
genre_list=['melodic punk','alt rock','drum and bass','house','punk rock'] 
song_list=["Welcome to Paradise.wav","Worry Rock.wav","Propane Nightmares.wav","Lalula.wav","Life During Wartime.wav"] 
i=0 
s=0 
#Here I am providing the participant with the ability to play a song 
decision=input("Guess the genre of the song! (enter any key to play a song. Enter -1 to finish the quiz)") 
if decision == '-1': 
      exit() 
else: 
    pw.play(song_list[s])   


#Here I am showing the participant the list of possible genres to choose from. 
print("heres a list of my favorite genres!") 
print(genre_list) 
#Here the participant guesses the genre  
genre=input("What genre do you think that was?") 
#If the genre is correct, it plays the next song, if it is not in genre_list, it stops.  
while genre == genre_list[i]: 
    print("Great guess! %s is correct!"%(genre)) 
    choice=input("Ok, so now that you got that right, ready to try another? (y/n)") 
    if choice.lower() == 'y': 
     i+=1 
     i%=5 
     pw.play(song_list[s]) 
    else: 
     break 

這裏是代碼playWav2：

""" Play a WAVE file. """ 

import pyaudio 
import wave 

chunk = 1024 

def play(song): 
    wf = wave.open(song, 'rb') 
    p = pyaudio.PyAudio() 

    # open stream 
    stream = p.open(format = p.get_format_from_width(wf.getsampwidth()), 
       channels = wf.getnchannels(), 
       rate = wf.getframerate(), 
       output = True) 

    # read data 
    data = wf.readframes(chunk) 

    # play stream 
    while data != '': 
     stream.write(data) 
     data = wf.readframes(chunk) 
    stream.stop_stream() 
    stream.close() 
    p.terminate()

的錯誤不是在上面的代碼，但在你的模塊playWav2

當你列出pyaudio作爲參考，看看The example on the pyaudio page，示例專門的結局..

或提供鱈魚e用於playWav2。
