        self.folderSerach = [f for f in os.listdir() if f.endswith(('.wmv','mp4','avi','.jpg'))]
        self.media.Load(self.folderSerach[self.mediaCounter])

    def auto(self):

    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()

我正在创建一个面板来搜索和播放文件夹中的 jpg、avi、mp4 等文件。

在def mediaPlay()段中，jpg使图片文件可见10秒，电影播放到播放时间结束。

问题是，if = '.jpg'，只需要执行一条print ('test1')语句，同时会显示'test2'。因此 time.sleep() 应用于 if or else 语句。这是为什么？

Answer 1

在此函数中，您将用文件后缀列表覆盖 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')

替换为：

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')

覆盖 self.folderSerach 意味着您必须在 def medialoop 中重新加载它（删除该代码）

此外，os.listdir()（至少在 Linux 上）需要一个参数，即 os.listdir('./')
并且，删除未使用的 def auto 函数
