如何在Python中播放MP3而没有无限循环？

Question

I am writing a program which reads a string, then convert it into speech and play it as mp3. But the program does not play the music. I have checked and find out that the mp3 file is created and can be played with standard mp3 players but not the script. I am using gtts module (for converting text to speech) and vlc module (to play mp3) The code is like this.Please note that 'm' is the text I want to convert to sound.

tts = gTTS(text=m, lang='en')
tts.save("greeting.mp3")
p = vlc.MediaPlayer("greeting.mp3")
p.play()

I have further found out that the mp3 plays when I provide an infinite loop after play command.Like this

tts = gTTS(text=m, lang='en')
tts.save("greeting.mp3")
p = vlc.MediaPlayer("greeting.mp3")
p.play()
while True:
    pass

Is there any way I can avoid that Infinite loop.I have already imported all the required modules to the project.

Answer 1

What you are doing is starting a subprocess with the vlc lib, when your program closes, it closes the subprocess. So the quickest solution (without learning how to properly handle processes) is to set sleep timer:

import time

tts = gTTS(text=m, lang='en')
tts.save("greeting.mp3")
p = vlc.MediaPlayer("greeting.mp3")
p.play()
time.sleep(120) # number of seconds in

However, there is this solution for finding the length of media so the sleep period can be set from code.
