Nearly every desktop application that can open one or more files has a file dialog.
An open file dialog may seem like a very complicated window to create: it contains buttons, locations, labels and many more widgets. Moreover, the appearance of this open file dialog looks different on every platform: Mac OS, Windows and so on.
The wxPython module comes with open file dialogs, which can be created with a few functions calls.
