The code should go into class klass: in place of the comments, if I
would know what to write there I wouldn't be asking the question :)

Sorry, I just wanted to illustrate that the output should depend on
the method called.
But maybe it's imprecise and misleading so let's forget about the
difference in ordering.

Well, I would normally do what you suggest, using parameters, but in
the example at hand I have to have the method names as variables and
the reason is that the whole thing will be run by apache using
mod_python and the publisher handler. There a URL
http://something.com/program2/Bob is mapped to the 'Bob' method of the
file program2.py and I want to be able to have URL's with different
names. I know I can solve this problem with parameters and functions
and using the GET http method, but I would like to have pretty URL's
without & and ? signs. I didn't want to ask this on the mod_python
list because after all it's a pure python question.
So I try again, hopefully it will be clearer this time:
--------- database content -----------
Alice 25
Bob 24
--------- program1.py -------------
class klass:
# My question is what I should write here
# assuming that I can query the database
# using the names of the fields (name and age)
# but without knowing in advance what will be
# the result of the query.
# The desired result of the code that should
# come here (which I don't know, but asking you guys)
# will be described below.
inst = klass()
--------- program2.py -----------
import program1
# The code in klass above should be such that the following
# line should print 'Hello my name is Bob and I'm 24.'
program1.inst.Bob()
# The code in klass above should be such that the following
# line should print 'Hello my name is Alice and I'm 25.'
program1.inst.Alice()
# The code in klass above should be such that the following
# line should print 'There was an error.'
program1.inst.John()
-------------------------------------------------------
I hope it's clear now that what I need is variable method names, the
wording 'generating' was probably also misleading and imprecise.
Thank you very much in any case.
