With this code:

quit_menu_item = wx.MenuItem(File_menu, wx.ID_EXIT)
parent.Bind(wx.EVT_MENU, parent.on_quit_click, id=wx.ID_EXIT)

you are binding the Quit menu item to a Quit function.
Do the same for the Open function i.e. Bind it to something like parent.on_open_file

In that function, do something like this.

def self.on_open_file(self, event):
    dlg = wx.FileDialog(self, message="Choose file", defaultDir = "/home", defaultFile = "",\
                        wildcard = "", style=wx.FD_OPEN)
    if dlg.ShowModal() == wx.ID_OK:
        print(dlg.GetDirectory(), dlg.GetFilename())
    dlg.Destroy()
