     #Video Image File Folder Serach & Load Play 
     self.mediaCounter = 0 
     self.folderSerach = [f for f in os.listdir() if f.endswith(('.wmv','mp4','avi','.jpg'))] 
     self.media.Load(self.folderSerach[self.mediaCounter]) 
     self.media.Bind(wx.media.EVT_MEDIA_LOADED, self.mediaPlay, self.media) 
     self.media.Bind(wx.media.EVT_MEDIA_FINISHED, self.mediaLoop, self.media) 


    def auto(self): 
     self.TextShow() 
     wx.CallLater(1000, self.auto) #60min 

    def mediaPlay(self, event): 
     self.folderSerach = [x for f in os.listdir() for x in os.path.splitext(f) if x.endswith(('.wmv','mp4','avi','.jpg'))] 
     for i in self.folderSerach: 
      if i == '.jpg': 
       self.media.Play() 
       time.sleep(10) 
       print('test1') 
      else: 
       self.media.Play() 
       print('test2') 

    def mediaLoop(self, evnet): 
     self.media.Stop() 
     self.mediaCounter += 1 
     if self.mediaCounter > len(self.folderSerach) -1: self.mediaCounter = 0 
     self.folderSerach = [f for f in os.listdir() if f.endswith(('.wmv','mp4','avi','.jpg'))] 
     self.media.Load(self.folderSerach[self.mediaCounter]) 

if __name__ == '__main__': 
    app = wx.App() 
    fream = MainFream() 
    fream.Show(True) 
    app.MainLoop() 

我正在創建一個面板來搜索和播放jpg，avi，mp4等文件夾。

在def mediaPlay()部分，jpg使圖片文件可見10秒，並且電影被播放直到播放時間結束。

問題是，if = '.jpg'，只有一個print ('test1')聲明需要執行，'test2'將同時顯示。所以time.sleep()適用於if or else聲明。爲什麼是這樣？

Answer 1

在此功能中，您將用文件後綴列表覆蓋self.folderSerach。

def mediaPlay(self, event): 
    self.folderSerach = [x for f in os.listdir() for x in os.path.splitext(f) if x.endswith(('.wmv','mp4','avi','.jpg'))] 
    for i in self.folderSerach: 
     if i == '.jpg': 
      self.media.Play() 
      time.sleep(10) 
      print('test1') 
     else: 
      self.media.Play() 
      print('test2') 

其替換爲：

def mediaPlay(self, event): 
    if self.folderSerach[self.mediaCounter].endswith('.jpg'): 
     self.media.Play() 
     time.sleep(10) 
     print('test1') 
    else: 
     self.media.Play() 
     print('test2') 

的self.folderSerach這重寫意味着你不必在def medialoop再次重新加載（刪除代碼）

另外，os.listdir()（至少在Linux上）需要一個參數，即os.listdir('./')
並且，刪除def auto函數它不被使用
