What you show above is composition, and is a perfectly valid technique, and in fact should often be *preferred* to inheritance. The only slightly dubious part, and I stress *slightly*, is that there is a circular reference: w refers to serv, and serv refers back to w. While legitimate, it is a very slight "code smell" that should be investigated. If there is a way to get the same result without the circular reference, that would be preferred. For example, perhaps server methods that need to know the world could take it as an explicit argument, rather than fetching it implicitly from server.world. Or, a moderately advanced technique, use a weak-ref instead. Inheritance should only be used to model "is-a" relationships. For example, Herbie the Love Bug is a Volkswagen Beetle, so inheritance is appropriate. http://en.wikipedia.org/wiki/Herbie class Vehicle(object): pass class Car(Vehicle): pass class Beetle(Car): pass herbie = Beetle() Composition should be used to model "has-a" relationships. For example, a car has an engine, it is not a kind of engine, and so inheritance is inappropriate and composition should be used. I would re-write the Car class as follows: class Engine(object): pass class Car(Vehicle): def __init__(self): self.engine = Engine() So now we can talk about Herbie's engine: herbie.engine # Herbie, being a car, has an engine, he is not an engine -- Steven -- http://mail.python.org/mailman/listinfo/python-list

The latest edition (3rd?) of Programming Python by Mark Lutz covers py3k (it targets 3.0/3.1 IIRC, but the official Python docs cover the differences between versions). The tutorial in the official docs is short compared to a book, but it covers the basics well. The official docs do cover each module in the standard library in great detail. It is mainly reference, though there are a few tutorials (e.g. the logging module has at least 2 tutorials). If you are not restricted to 2.x, learn 3.2/3.3. 2.x is used mainly because some major libraries (e.g., Twisted, Django) and/or other dependencies do not support 3.x yet.

From what I understand and how I've always employed it, inheritance is ment when you wish to give a class characteristics of another class. All I'm doing here is setting the world and server classes on each other, so they can call one another. This probably isn't needed in case of serv.server = w, but for sure the other way around. -- Take care, Ty http://tds-solutions.net The aspen project: a barebones light-weight mud engine: http://code.google.com/p/aspenmud He that will not reason is a bigot; he that cannot reason is a fool; he that dares not reason is a slave. -- http://mail.python.org/mailman/listinfo/python-list

It also seems you are doing things quite java like, but I guess that is just a thing of getting used to python.

No, the format specification is the part after the ":" (if present), as
in the example.
Here are more examples:
>>> c = "foo"
>>> print "{0}".format(c)
foo
>>> format(c, "")
'foo'
>>> print "To 2 decimal places: {0:0.2f}".format(1.2345)

Thanks. I think it's coming together.
Either way, this format seems uglier than what I had before, and it's longer to
type out. I suppose that's just programmers preference.

That's not actually the output copied and pasted. You have quotes around
the string, which you don't get if you pass it to the print command.
print format(c,s)

Because the format built-in function is not the same as the format string
method.
The string method takes brace substitutions, like "{0[0]}" which returns
the first item of the first argument.
The format function takes a format spec, not a brace substitution. For
example:
>>> format(c, '<10s')
'(1, 3)'
>>> format(c, '>10s')
'(1, 3)'
>>> format(c, '*>10s')
'(1, 3)'
The details of the format spec are in the Fine Manual:
http://docs.python.org/library/string.html#formatspec
although sadly all the examples are about using brace substitutions, not
format specs.
(Personally, I find the documentation about format to be less than
helpful.)
You can also read the PEP that introduced the new formatting, but keep in
mind that there have been some changes since the PEP was written, so it
may not quite match the current status quo.

while {condition that the loop continues}:
{what to do in the loop}
{have it indented, usually four spaces}
{the code here is not looped}
{because it isn't indented}
Just discovered this in the tutorial further down. I'm currently learning
Python 2 because there seems to be a lot of tutorials out there covering Python
2 rather than 3.
Thanks for the help this community is great for help.

Rather then write a decorator, sounds like you should write your own class or method connecting to the database that has the ability to retry. Are you finding you are decorating only db calls or are you decorating all sorts of stuff? -- http://mail.python.org/mailman/listinfo/python-list
Re: retry many times decorator
On the other hand now that I think again even supposing there is a permanent error like MySql completely down, retrying continuosly won't do any harm anyway because the machine will not be able to do anything else anyway, when someone will fix MySql it would restart again without human intervention. So I think I could even just let it retry and use maybe a SMTPHanlder for the logging errors, to make the notification of problems very quick.. -- http://mail.python.org/mailman/listinfo/python-list
