Permission error in Python, when working with audiosegment in Windows 10-CodePudding

I wrote a short text to play the audio file. But when running, the program gives error permission. I noticed that every time I run the program, the name of the file that has the permission error is different This file is in the temp path I checked this path and there was no file with that name

Program text:

from pydub import AudioSegment
from pydub.playback import play

try:
     song=AudioSegment.from_wav("myfile.wav")

except IOError:
    print("can not open file")

try:
    play(song)
except IOError:
    print("can not play file")

The output of the program was as follows:

My Project Python/my project python/play wav.py"
can not play file

When I try the program without the block Try: , the output is as follows:

Traceback (most recent call last):
  File "d:\My Project Python\my project python\play wav.py", line 7, in <module>
    play(song)

I found an answer for this question, but it is not an optimized answer

def _play_with_ffplay(seg):
  PLAYER = get_player_name()
  with NamedTemporaryFile("w b", suffix=".wav") as f:
     fileName = f.name  
  seg.export(fileName, "wav") 
  subprocess.call([PLAYER, "-nodisp", "-autoexit", "-hide_banner", fileName])
  os.remove(fileName)

I made these changes in the playback.py file and got the answer . link

This also works:

def _play_with_ffplay(seg):
PLAYER = get_player_name()
with NamedTemporaryFile("w b", suffix=".wav") as f:
    f.close()
    seg.export(f.name, "wav")
    subprocess.call([PLAYER, "-nodisp", "-autoexit", "-hide_banner", f.name])

Just close the file with the f.close() command
