I had a look at it, but I've got about as far as "Hello World" in both. I borrowed a book called "Learning Python" by Lutz and Asher, which is geared for 2.2/2.3.

I was thinking or of this:
>>> python g:\work\module1.py
File "", line 1
python g:\work\module1.py
^
Which gave a different error the previous time I did it.
But, hey, it worked from the DOS prompt
C:\Python32>python g:\work\module1.py
Hello Module World
But hey, don't mind me.
The biggest problem I have is that when something doesn't work, I don't know
if I have done something stupid, or if it's just an incompatibility of the
different versions.

Though you can use any language to write any kind of program in theory, in practice some languages are designed to write certain kinds of programs more easily and more quickly -- Prolog for AI programs, for example. So the question is, which kinds of programs is Python best for? I'm a novice at it, so it's a question that concerns me. From what I've heard and read, it seems to be a fairly good general-purpose language, and it seems to be most used for writing web applications (though that is not something I am particularly interested in). -- Steve Hayes from Tshwane, South Africa Web: http://www.khanya.org.za/stevesig.htm Blog: http://khanya.wordpress.com E-mail - see web page, or parse: shayes at dunelm full stop org full stop uk -- https://mail.python.org/mailman/listinfo/python-list

Python modules
I have a book on Python that advocates dividing programs into modules, and importing them when needed. I have a question about this.

Using Python for date calculations
I've finally found a use for Python.
When, in the course of my genealogy research, I look at census or burial
records, I often want to work out a person's date of birth from their age.
It's a simple matter of mental arithmetic, but I sometimes get it wrong, and
mislead myself. There are calculators and date calculation programs, but they
are usually too complicated and try to do too much, so by the time you've
worked out what to do it takes much longer.
This Python script does it for me.
year = input("Year: ")
age = input("Age: ")
born = year-age
print 'Year of birth:', born
It's so simple, so elementary, that it's not really worth writing about,
except for the fact that it illustrates the KISS principle.
It is sometimes better to have a simple program that does one thing well than
a complex one that does lots of things, but none of them very efficiently.
The average hand calculator can do the same job, but you have to pick it up
and put it down, and you can't easily see if you've made a typo.
Having said that, however, yes, I would perhaps like to use Python for more
complicated date processing routines, namely to convert the kinds of dates
produced by genealogy programs to a simple -mm-dd that computer database
programs can understand, so that "Abt May 1677" would be rendered as
"1677-05-00"
Has anyone done something like that in Python?

I though input() was OK for integers.

So it might be a year out in the case of burials, nut in the case of many
censuses they would be more likely to have been born the year before, since
most censuses are taken i8n tyhe first part of the year. So the calculation is
a rough one, but that's all I need. If sommeone is 20 in the 1871 census, I'd
put them down as born about 1850, which probably has a 65% chance o0f being
right.

Except that most of those examples seem to assume that you are calculating
from the current date, rather than the date of a census or the date of a
burial. Useful for future reference, perhaps, but not for the immediate
purpose of getting a rough idea of whan a person might have been born (people
also lied about their age on censuses).
There's a date calculator in my Legacy genealogy program, which is doubtless
more accurate, but it takes too many mouse clicks to get there, and then to
get back to where I was.
I've got another nifty little utility called RJT Datecalc, which does the more
accurate stuff, but still has too many options and is too time-consuming.
What I'm beginning to like Python for is the ability to do quick 'n dirty
little scripts for quick 'n dirty little jobs that save time and do what I
need.
For example, I see the age of someone in a UK census, and I want to know
roughly which years I should look for their birth in something like FreeBMD.
If it says 1847, obviously I'll look for a couple of years either side because
chances are they were born in the previous year, and the age might not have
been accurate anyway.

I thought left-wing types were particularly prone to using such terms, and tend to freely call anyone even slightly to the right of them "fascist".

I found all the Python books available dealt with version 2.x, so
eventually I installed that for the purpose of learning Python.
It's much easier, and you don't have to spend hours searching online
for differences between 3.x and 2.x just to find what caused an error
in an example script.
Once you've l;earnt it, then you can start learning the differences,
and maybe by that time there will be a book that deals with 3.x, but
until there is, it's just not worth the hassle unless you're seriously
into Unicode.
