You create your user interface by subclassing wx.Panel. You need to define a dictionary to hold and store the data about your MP3s, here we are naming it as row_obj_dict. Next, you create a wx.ListCtrl and set it to report mode by the following code wx.LC_REPORT and set a sunken...
However, it’s now also the recommended syntax to fill in a suite in a stub file: Python # In a `.pyi` file: def add(a: int, b: int)-> int: ... This function not only does nothing, but it’s also in a file that the Python interpreter never evaluates. Raise an Error In...
