Question

我有一个需要在Windows Media Player中打开文件的程序，因为在文件完成后，它需要杀死wmplayer.exe。我尝试过使用subprocess.Popen(["C:\Program Files (x86)\Windows Media Player\wmplayer.exe", my_file])和subprocess.call(["C:\Program Files (x86)\Windows Media Player\wmplayer.exe", my_file])，但这只是打开Windows Media Player;不是我要打开的特定文件。（my_file变量存储.mp3文件的路径（它与.py文件位于同一文件夹中），并在我在代码中使用它的其他地方工作，当我使用webbrowser.open时）。< / p>

完整代码：

try:

    import webbrowser
    import os
    import time
    import sys
    import getpass
    import pip
    import subprocess
    from contextlib import contextmanager

    @contextmanager
    def suppress_stdout():
        with open(os.devnull, "w") as devnull:
            old_stdout = sys.stdout
            sys.stdout = devnull
            try:  
                yield
            finally:
                sys.stdout = old_stdout

    with suppress_stdout():
        pkgs = ['mutagen', 'gTTS']
        for package in pkgs:
            if package not in pip.get_installed_distributions():
                pip.main(['install', package])

    from gtts import gTTS
    from mutagen.mp3 import MP3

    my_file = "Text To Speech.mp3"

    username = getpass.getuser()

    def check_and_remove_file():
        if os.path.isfile(my_file):
            os.remove(my_file)

    def input_for_tts(message):
        tts = gTTS(text = input(message))
        tts.save('Text To Speech.mp3')
        subprocess.call(["C:\Program Files (x86)\Windows Media Player\wmplayer.exe", my_file])

    check_and_remove_file()

    input_for_tts("""Hello there """ + username + """. This program is
used to output the user's input as speech.
Please input something for the program to say: """)

    def text_to_speech():
        while True:
            audio = MP3(my_file)
            audio_length = audio.info.length
            time.sleep((audio_length) + 0.25)
            os.system('TASKKILL /F /IM wmplayer.exe')
            time.sleep(0.5)

            while True:
                answer = input("""
Do you want to repeat? (Y/N) """).strip().lower()
                if answer in ["yes", "y"]:
                    input_for_tts("""
Please input something for the program to say: """)
                    return text_to_speech()
                elif answer in ["no", "n"]:
                    check_and_remove_file()
                    sys.exit()
                else:
                    print("""
Sorry, I didn't understand that. Please try again with either Y or N.""")

    text_to_speech()

except KeyboardInterrupt:

    check_and_remove_file()
    print("""
Goodbye!""")
    sys.exit()

是否有人知道如何确保使用Windows Media Player打开该特定文件，而不仅仅是Windows Media Player？

Answer 1

WMP可能希望播放媒体的完整路径并且不关心脚本执行的位置。尝试：

wmp = r"C:\Program Files (x86)\Windows Media Player\wmplayer.exe"
media_file = os.path.abspath(os.path.realpath(my_file))
subprocess.call([wmp, media_file])

Answer 2

如果将Windows Media Player设置为.mp3文件调用的默认播放器

os.startfile(path_to_your_mp3)

应该有用。

如何确保使用Python中的Windows Media Player打开.mp3文件？
