Question

我对编程很态度，但希望学习和发展。

我想写一个在语言治疗中有用的简单应用程序 - 但首先它是简单的演示。

应用程序即将在投影期间显示图像和录制声音。几乎没有变量 - 间隔和图像/声音/影片剪辑路径 - 取自外部txt文件（开头 - 后来我想用预先配置的配置执行一些创建者）。

配置文件现在看起来像：

10
path1
path2
...

第一行是以秒为单位输入间隔，接下来是图像，声音或影片剪辑的路径（我现在尝试使用图像）。

当问及一些程序员关于代码时，它就像骑自行车一样简单，所以我想学习如何自己编写代码。

我想这对于专业人士来说是和平的蛋糕 - 感谢那些想要阅读这些垃圾的人们。

我需要花很多时间才能理解和弄清楚我正在礼貌地询问帮助的确切信息 - 不仅是为了教育而且是为了更好的诊断。

请原谅我的语言 - 英语不是我的母语。
