这段代码是一个方法,方法名为 `compare_openaduio2`,它的作用是打开一个文件对话框,让用户选择一个音频文件,并将选择的文件路径显示在界面上某个名为 `lineEdit_4` 的文本框中。
具体来说,`self.openFile()` 是一个自定义的方法,用于弹出一个文件对话框,让用户选择一个文件,并返回选择文件的路径。而 `self.compare_audio_path2` 是一个实例变量,用于保存用户选择的文件路径。`self.lineEdit_4.setText()` 则是将该路径设置为文本框 `lineEdit_4` 的文本内容。

解释代码defcompare_openaduio1(self): self.compare_audio_path1=self.openFile() self.lineEdit_3.setText(self.compare_audio_path1)
这段代码定义了一个名为`compare_openaduio1`的函数,这个函数包含三行代码:
1. `self.compare_audio_path1=self.openFile()`:调用了一个名为`openFile()`的函数,将其返回值赋值给`self.compare_audio_path1`。根据函数名猜测,这个函数可能是用来打开文件的。因此,这一行代码的作用是打开一个文件,并将文件路径存储在`self.compare_audio_path1`这个变量中。
2. `self.lineEdit_3.setText(self.compare_audio_path1)`:将`self.compare_audio_path1`这个变量的值设置为`lineEdit_3`这个控件的文本。根据变量名和控件名的猜测,这个控件可能是用来显示文本的,因此这一行代码的作用是将`compare_audio_path1`的值显示在界面上。
总之,这段代码的作用是选择一个音频文件,并将其路径显示在界面上的一个文本框中。

你忘记了在导入模块时使用逗号分隔,应该改为:
