class Loud(wx.Frame):

  def __init__(self,parent,id,title):
    wx.Frame.__init__(self,parent,id,title,size=(300,200))

    txtu = wx.TextCtrl(self, -1 )

    btnco = wx.Button(self, -1,"Co",pos=(0,30))

    self.Bind(wx.EVT_BUTTON, self.OnCo(txtu.GetValue()), id =
btnco.GetId())

  def OnCo(self,event,txt):

Minimum changes to make it go:

import wx

class Loud(wx.Frame):

    def __init__(self,parent,id,title):
  wx.Frame.__init__(self,parent,id,title,size=(300,200))

  self.txtu = wx.TextCtrl(self, -1 )

  btnco = wx.Button(self, -1,"Co",pos=(0,30))

  self.Bind(wx.EVT_BUTTON, self.OnCo, id = btnco.GetId() )

    def OnCo(self,event):

        txt = self.txtu.GetValue()
        print txt

app = wx.App()
frame = Loud(None,-1,"Loud")
frame.Show()
app.MainLoop()

Well, you should understand what you did wrong.

self.Bind(wx.EVT_BUTTON, self.OnCo, id = btnco.GetId() )

Bind takes a function *pointer*. That is, a reference to a function
  • without any braces. Your code is “calling” self.OnCo and passing
    its return value as the function to bind to. In the fixed code, you
    can see how self.OnCo itself is used, not self.OnCo(blah…)
