I have a code. When it runs, you click on add contact button and add some contact. When you press on each contact, it just shows you the last contact information you have added. But when I press on each contact, I want it to instead show me the information for the contact I have clicked. Who can help me to solve this problem?

Everyone will develop their own style when using wxPython. As Rolf has suggested, you do not just add widgets to a frame, but you need to add a panel. I have added a basic contact add screen below. The 'New' button creates an instance of a wx.Dialog, which captures the details of a contact. These are then available to the MainFrame where you can save them if you want.
Note that I have freely created new classes in the application to handle the different areas of concern. GUI apps can become very complex, and in my opinion, there is no substitute for factoring each bit of functionality into its own method or class.
Not everything needs to be a member of the frame class.
Note also the I have used sizers and not absolute positions.
This code does not do everything that you want to do, but it might help get you started.

I have a python 3 (wxpython phoenix) app which has two TABs, each TAB has a OnDropFiles box, but I just can't get it working. I have a simple stripped down example below, which should print the file URL on each drop, but not working, if someone could show a working example please, or point me in the right direcion, I would be very gratefull.

We want this to be event driven, so you should define an event, from wx.lib.newevent.
I assume you want the drop zone to be the textctrl not the whole panel, so it's that that needs to be set as the target.
BIND the event.
In the FileDropTarget class we define the event and fire it.
In each drop event callback, we accept the event as a parameter and unpack whatever we packed into the event.
One last thing, in this case, you are getting back a list.
It's simple but every time you decide to use it, it trips you up, I don't know why.

I want to start an app with several panels hidden from the user and show them per request when interacting with the menu.

need some help
thank u
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()
I would like to assign the value of a menu click to a class variable so I can use that value throughout multiple classes. Any help would be greatly appreciated!

This is the fast and dirty method I generally use. If you want something more sophisticated, there is a dedicated library to pass messages between frames: pubsub. A good tutorial of how to use it can be found in the Mike Driscoll blog
