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.

Switching to PostgreSQL will give you all those kinds of features, plus a lot of other things that I would have thought pretty basic - like ALTER TABLE. It was quite a surprise to learn that SQLite3 didn't support that. I see you're running a lawnmower. Maybe you should switch to a combine harvester. That'll get you extra features like a reciprocating knife cutter bar. I was quite surprised that regular lawnmowers don't support those. SQLite3 is fine for something that's basically just a more structured version of a flat file. You assume that nobody but you has the file open, and you manipulate it just the same as if it were a big fat blob of JSON, but thanks to SQLite, you don't have to rewrite the whole file every time you make a small change. That's fine. But it's the wrong tool for any job involving multiple users over a network, and quite probably the wrong tool for a lot of other jobs too. It's the smallest-end piece of software that can truly be called a database. I would consider it to be the wrong database for serious accounting work, and that's based on the ranting of a majorly-annoyed accountant who had to deal with issues in professional systems that had made similar choices in back-end selection. You're welcome to disagree, but since PostgreSQL doesn't cost any money and (on Linux at least; can't speak for other platforms) doesn't take significant effort to set up, I will continue to recommend it.

For those few cases where there is no plain text part[1], the better mail clients (such as mutt) will include an option to dump the raw HTML to plain text, minus all the tags.

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? -- 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

[snip] This is keeping it too simple. Someone aged 50 (i.e. over 50 but not yet 51) today - 21st Nov 2014 - might have been born in 1963 or 1964 depending on their birthday. For me your calculation would return the correct answer (born in March), for my sister it would be wrong (born in December). 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. -- 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

Run your program and respond to the prompt with

(on a Windows system... If Linux replace the 'del...' with 'rm -rf *' )
Those don't look like integers to me.

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. -- 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

I made a lot of automated computations from census. In Quebec, we have censuses for 1666, 1667 and 1681, and also ages in some marriage records, marriage contracts, burials, and some more records. In Acadia, there are other old censuses. Sometimes, the result is accurate, i.e. there is a known baptism and the age is matching, but in many cases either the age is not matching or the year of birth is changing a lot depending on the record. So, if the computation is made to give a hint about the birth year, then the month is irrelevant. The result will be about that year and not that year. In the database I sell, I write exactly that, i.e. (actual example, from Acadian censuses) : Germain, born about 1650 (census 1671), 1652 (census 1686) (census 1693), 1650 (census 1698) or 1649 (census 1699) Marguerite, born about 1658 (census 1671), 1660 (census 1693), 1658 (census 1698) or 1661 (census 1699) Exactly!

Indianapolis: Sams. ISBN: 978-0-672-33687-4 For Python 2.7.5 I can understand doing that in a compiled language, where different modules can be imported from all sorts of places when the program is compiled. Python is a compiled language; when you run a Python program a necessary step is to compile the Python source to a bytecode for actual execution. Usually, the compilation step is done dynamically; but (barring contrived examples) it is always done prior to running the program. But I understand that Python is an interpreted language The two are not mutually exclusive. The Python interpreter works with compiled Python code, it does not execute the source directly. If I wrote a program in Python like that, and wanted to run it on another computer, how would it find all the modules to import at run-time, unless I copied the whole directory structure over to the other computer? That's the idea, yes. You need to distinguish between: * The standard library: installed along with the Python interpreter when you install that, and available on the default module search path. * Third-party modules: installed using your package manager (ideally by the operating system package manager), again to a location already part of the default module search path on your system. * Modules specific to the application you're writing: Keep these in a known hierarchy, and use the distribution tools to package them to keep them together when distributing to oher machines. Use abolute import for standard library and third-party modules. Use relative import for application-private modules. This ensures your aplication's private modules don't conflict with current or future names of modules from the standard library or third parties.

Version 2.7 is a good choice, and it will be around for a long time: it will be supported until at least 2020, so you should get many years of use from it. Do not be discouraged about Python 3. There are differences, but they aren't so different as to be a major barrier. By the time you have a bit of experience with 2.7, you will be more than capable of dealing with the differences with version 3. They are not different languages, think of them as slightly different dialects of the same language, like UK and South African English.

I only ask becuase I am starting off with python and I want to learn everything in basic and advanced programming with python itself...So any advice and suggestions would be more than welcome. Thanks!! That's a really hard question to answer, or at least to answer well. At a theoretical level, when you ask, Is Python equivalent to C, C++ and Java, the answer is yes. In computer science, programming languages are classified by whether they are Turing Complete or not (google that for more info). In theory, any Turing Complete language is capable of writing all programs which can be written in any other Turing Complete language. All of the languages you mention are Turing Complete, so, theoretically, they are all equivalent. But, at a more practical level, some languages are easier to learn, some run faster, some are more portable, some are more convenient to use, etc. If I had to rank the languages you mention by a few categories, I'd say something like: I think the significant thing is that some languages are easier to use for some things than for others. 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
