new to python.. help needed

[wizzkid]

I follow this this site http://www.arson-network.com/index.php?class=tutorial&subargs=430

im not sure if I have these:
Python = installed as defaul. .2.4
GTK
Glade = installed
pyGTK
pyGlade
the other im not sure.. how to check.

But I followed and created the program. but I encounter error upon running ./swap.py

Error is:
(swap.py:11343): Gdk-WARNING **: locale not supported by Xlib

(swap.py:11343): Gdk-WARNING **: cannot set locale modifiers
Traceback (most recent call last):
File "./swap.py", line 69, in ?
app=gui() #9
File "./swap.py", line 39, in __init__
dic = {"on_swap_clicked" : #2
AttributeError: gui instance has no attribute 'on_swap_clicked'

I've attached the tar.gz file which contains the cource code..

Sorry. Im a newbie that want to learn programming. this is my first step in python

thanks

You have an indentation error.

Line
def on_swap_clicked(self,widget):
needs to be indented to the same level as
def __init__(self):

The indentation must look like

class SomeClass(object):
def __init__(self):
self.some_attr = None
def some_method(self):
print 'Doing some method.'

def some_function():
print 'This is not a SomeClass method.'

The two best free online Python books are, in my opinion, byte of python (http://www.byteofpython.info/) and dive into python (http://diveintopython.org/). Both can be downloaded in a variety of formats and languages, or read online. Byte of python is more beginner oriented, but dive into python is more in-depth and goes into more commonly used modules, not just stuff included with Python itself.... I found it very helpful when learning XML parsing.

Anyway, good luck with Python. It's a great programming language.
