wxpython Timer not working

As reading "wxPython in Action" I tried the code in the book, a simplified piece, as follows: 

import wx 
import time

class Frame(wx.Frame):  
    def __init__(self, *args, **kwargs):  
        wx.Frame.__init__(self, *args, **kwargs)  
        timer = wx.Timer(self,-1)  
        self.Bind(wx.EVT_TIMER, self.OnTimer,timer)   
        timer.Start(1000, True)  
        self.Show()  
    def OnTimer(self, evt):  
        print time.time(), evt   

app = wx.App(False) 
frm = Frame(None, -1)  
app.MainLoop()

When I run this, python gives no error, but it does not print anything either.
weird, anybody knows why?

The reason that doesn't work is because the timer goes out of scope at the end of the init method and doesn't really have a chance to run. As GP89 already pointed out, you need to just change it to be "self.timer" and it should work. I also have a tutorial you can check out.

Change timer to self.timer and it will work.

I'd be interested to know the reason why it doesn't work as a local variable

I'd guess at something to do with garbage collection though
