This is something simple that I cannot get my head around!
In one module I set up a wx gui, that has some buttons which are bound to events, and some like wxlabel which are not.
this is imported into a second module, within which the attributes for the widgets are manipulated eg "button_1.Hide()" This works fine for the widgets that are bound to events, but not if that is not the case eg label_1.Hide(). I am pretty new at this and have tried everything to acheive this unsuccessfully

#first module  first.py

import wx

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        # begin wxGlade: MyFrame.__init__
        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self, *args, **kwds)
     
        self.SetSize((400, 300))
        self.SetTitle("first")

        self.panel_1 = wx.Panel(self, wx.ID_ANY)

        label_1 = wx.StaticText(self.panel_1, wx.ID_ANY, "Password:", style=wx.ALIGN_CENTER_HORIZONTAL)
        label_1.SetMinSize((80, 30))
        label_1.SetFont(wx.Font(12, wx.FONTFAMILY_DEFAULT, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_BOLD, 0, ""))
        sizer_1.Add(label_1, 0, wx.LEFT, 50)

        sizer_1.Add(sizer_4, 1, wx.EXPAND, 0)

        self.button_1 = wx.Button(self.panel_1, wx.ID_ANY, "hide")
        self.button_1.SetMinSize((80, 23))
        sizer_1.Add(button_1, 1, wx.LEFT, 50)
        self.Layout()
        self.Bind(wx.EVT_BUTTON, self.hide, self.button_1)
   
    def hide(self, event):  # wxGlade: MyFrame.<event_handler>
        print("Event handler 'hide' not implemented!")
        event.Skip()

class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame(None, wx.ID_ANY, "")
        self.SetTopWindow(self.frame)
        self.frame.Show()
        return True

# end of class MyApp

    def __del__( self ):
        pass
--------------------------------------------------------------

# second module "second.py"
import wx
import first

class MyApp(fileHide.MyFrame):
    def  __init__(self,parent):
        first.MyFrame. __init__(self,parent)
        
    def hide(self, event): 
        print('hide')
        self.button_1.Hide()

app = wx.App(False)
        
frame = MyApp(None) 
frame.Show(True)

frame.label_1.Hide()   # error no frame has no attribute label_1 ....

app.MainLoop()

So I want to access label_1 in the second module, how can I do this?
Thanks in advance

To enable frame.label_1.Hide() to work, label_1 needs to be an attribute of MyFrame in first.py
to do this change label_1 to self.label_1

The code you posted did not run, I tided it up and made it runnable
first.py

import wx


class MyFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self._create_controls()
        self._setup()
        self._create_sizers()
        self._create_binds()

    def on_button_1(self, event):
        print("Event handler 'on_button_1' not implemented!")
        event.Skip()

    def _create_controls(self):
        self.panel_1 = wx.Panel(self, wx.ID_ANY)
        self.label_1 = wx.StaticText(
            self.panel_1, label="Password:", style=wx.ALIGN_CENTER_HORIZONTAL
        )
        self.button_1 = wx.Button(self.panel_1, label="hide")

    def _setup(self):
        self.SetSize((400, 300))
        self.SetTitle("first")
        width, height = 80, 30
        self.label_1.SetMinSize((width, height))
        self.label_1.SetFont(
            wx.Font(
                12,
                wx.FONTFAMILY_DEFAULT,
                wx.FONTSTYLE_NORMAL,
                wx.FONTWEIGHT_BOLD,
                0,
                "",
            )
        )
        width, height = 80, 23
        self.button_1.SetMinSize((width, height))

    def _create_sizers(self):
        panel_sizer = wx.BoxSizer(wx.VERTICAL)
        self.panel_1.SetSizer(panel_sizer)
        # sizer_1.Add(label_1, 0, wx.LEFT, 50) # sizer_1 not defined
        # sizer_1.Add(sizer_4, 1, wx.EXPAND, 0) # sizer_1 & sizer_4 not defined
        # sizer_1.Add(button_1, 1, wx.LEFT, 50) # sizer_1 missing, button_1 not defined
        # sizer_1 = wx.BoxSizer(orient=wx.VERTICAL)
        panel_sizer.Add(self.label_1, 0, wx.LEFT, 50)
        panel_sizer.Add(self.button_1, 1, wx.LEFT, 50)
        self.panel_1.Layout()

    def _create_binds(self):
        # self.Bind(wx.EVT_BUTTON, self.hide, self.button_1) # do the bind directly on the button instance as follows
        self.button_1.Bind(wx.EVT_BUTTON, self.on_button_1)


class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame(None)
        self.SetTopWindow(self.frame)
        self.frame.Show()
        return True


if __name__ == "__main__":
    my_app = MyApp(False)
    my_app.MainLoop()

second.py

import wx

import first


# class MyApp(fileHide.MyFrame): # fileHide not defined
class MyFrame2(first.MyFrame):
    def __init__(self, parent):
        super().__init__(parent)

    def on_button_1(self, event):
        print("hide")
        self.button_1.Hide()


if __name__ == "__main__":
    app = wx.App(False)
    frame = MyFrame2(None)
    frame.Show(True)
    frame.label_1.Hide()
    app.MainLoop()

Thank you so much! Sorry it did not run, I missed some changes in the simplification. I used wxglade to make the gui and it obviiously didn't put in the "self" for the label. The only bit I do not understand is the "super().__init__(*args, **kwargs)" line, can you tell me what that does?

Thanks!

You can configure labels to store as attribute. Click on the label in the designer and look at the "Common" tab of the "Properties" frame. There you will see a checkbox "Store as attribute". It is not checked by default.
