wxpython use the same static text twice in FlexGridSizer.AddMany

Question

I would like to duplicate column headings in my first python GUI. I have tried the following

    bfont = wx.Font(10,wx.DEFAULT,wx.NORMAL,wx.BOLD)
    angle = wx.StaticText(panel,label="Angle")
    angle.SetFont(bfont)
    count_c = wx.StaticText(panel,label="Counts (C)")
    count_c.SetFont(bfont)
    count_u = wx.StaticText(panel,label="Counts (U)")
    count_u.SetFont(bfont)

    fgs.AddMany([(angle),(count_c), (count_u),
                 (angle),(count_c), (count_u)])


    vbox.Add(fgs, proportion=1,flag=wx.ALL|wx.EXPAND,border=5)

However this only shows me the second set of headers. How can this be done?

You cannot add the same widget to two different locations. Instead, you'll have to create separate widgets for each row. Since you want the same thing on each row, you can use a loop:

import wx

########################################################################
class MyPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)
        bfont = wx.Font(10,wx.DEFAULT,wx.NORMAL,wx.BOLD)

        vbox = wx.BoxSizer(wx.VERTICAL)
        fgs = wx.FlexGridSizer(rows=2, cols=3, vgap=5, hgap=5)

        # add two rows of widgets to the sizer
        widgets = []
        for i in range(2):
            angle = wx.StaticText(self,label="Angle")
            angle.SetFont(bfont)
            widgets.append(angle)

            count_c = wx.StaticText(self,label="Counts (C)")
            count_c.SetFont(bfont)
            widgets.append(count_c)

            count_u = wx.StaticText(self,label="Counts (U)")
            count_u.SetFont(bfont)
            widgets.append(count_u)

        fgs.AddMany(widgets)
        vbox.Add(fgs, proportion=1,flag=wx.ALL|wx.EXPAND,border=5)
        self.SetSizer(vbox)

########################################################################
class MyFrame(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Test")
        panel = MyPanel(self)
        self.Show()

if __name__ == "__main__":
    app = wx.App(False)
    frame = MyFrame()
    app.MainLoop()
