Python Playsound用法

1. 亲测发现Python Playsound库在Windows 10、Python 3环境上无法直接使用（2022年5月1日）；
2. 修改playsound.py为如下所示：

import logging
logger = logging.getLogger(__name__)

class PlaysoundException(Exception):
    pass

def _canonicalizePath(path):
    """
    Support passing in a pathlib.Path-like object by converting to str.
    """
    import sys
    if sys.version_info[0] >= 3:
        return str(path)
    else:
        # On earlier Python versions, str is a byte string, so attempting to
        # convert a unicode string to str will fail. Leave it alone in this case.
        return path

def _playsoundWin(sound, block = True):
    '''
    Utilizes windll.winmm. Tested and known to work with MP3 and WAVE on
    Windows 7 with Python 2.7. Probably works with more file formats.
    Probably works on Windows XP thru Windows 10. Probably works with all
    versions of Python.

3. 上方脚本已经是修改之后的最终版本，期中的修改的位置如下图所示：
   

4. 然后采用下方代码直接运行即可：

import playsound ( playsound  
playsound'D:/PyTimer/test.mp3')python main.py

5. 执行playsound 如果美妆pip install， 则只需要一下即可。
