For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

This example is described in the following article(s):

Source code: class_v_static.py Module: Y115
"""Use of Decorators to set up static methods and
class methods. Also the setting up of your own

        def action(*args,**kwargs):
                result = f(*args,**kwargs)
                print "Err ... ",
                return result
        return action

class something(object):
        def __init__(self,stuff):
                self.stuff = stuff
                something.count += 1
        def getstuff(self):
                return self.stuff

        def count_c(self):
                return something.count

        def count_c2(self):
