When we have 'stuff' like this: ### >>> stuff = [[0,'sdfsd','wrtew'], [1, 'rht','erterg']] ### then we can ask for an element out of 'stuff'. One thing we can do is variable assignment: ### >>> row = stuff[0] ### 'row' here is just an arbitrarily chosen variable name.

[0, 'sdfsd', 'wrtew'] is another element in 'stuff' [1, 'rht', 'erterg'] is another element in 'stuff' ### 'row' here is also used as a temporary variable name. In a 'for' loop, it is assigned to each element, as we repeat the loop's body.

Re: [Tutor] Walking a directory
Kent's suggestions are always my favorites, along with others,
c. --nevermind
To get the full path in your list-- change Kent's to this
import os
filelist = []
for root,directories,filenames in os.walk("Aircraft"):
for filename in filenames:
if filename.endswith("-set.xml"):
filelist.append(os.path.join(root,filename))
for x in filelist:
print x
What I want to do is rather simple, but I cannot find any good
documentation for something like this.
The directory structure is sort of like this:
Aircraft
A-10
+A-10cl-set.xml
+A-10fg-set.xml
For example Aircraft/A-10/A-10cl-set.xml
Now I want to loop though each aircrafts folder (such as A-10) and
find each *-set.xml file, get the aircraft part (such as A-10cl) and
add it to a list.
While this does seem simple, how is the question.
I know about the walk function, but cannot find any good examples for it.

On Jan 17, 2005, at 23:07, Bernard Lebel wrote: Okay... so if I follow you, a class that has methods not part of itself, it's not a static class...? So should I understand that a class that gets inherited methods can be considered OOP? Not exactly. Basically, object-oriented programming is just that; that is, working with objects, which are instances of classes. Now, class methods/attributes, which I call "static" because that's the C++/Java keyword that triggers them, are methods and attributes that are shared by all the instances of that class, not specific to a particular instance. The class doesn't even have to be instanciated (no objects have to be created) for them to be used. They are effectively part of the class itself, hence the name, class methods (as opposed to instance methods). A common use for class attributes is to keep track of how many times the class has been instanciated (number of objects created). So, if my class only has static methods and attributes, any object I create with that class is empty: it has no attributes of its own, and is impossible to be interacted with. Thus, you could just as well say it doesn't exist, and that the class can't be used to create objects. Therefore, you're using a class to do procedural programming. However, the class has its separate namespace: when you're calling methods from that class from outside its body, the call syntax is Class.method(). Which is exactly the same thing as using a function from Python module. I hope that answers your question... -- Max maxnoel_fr at yahoo dot fr -- ICQ #85274019 "Look at you hacker...

I appreciate it!! Alan, as you had suggested in an earlier post, I will put the pipe into a class of it's own. Actually I think I will make the command line version of the program. Once I have that working, then I can look at putting a GUI front-end on it. Like you said, 'Separating the GUI code from the logical functions is always a good idea'. I had just never considered doing it that way, what can I say, I'm just learning :-) It now makes complete sense to have the two separate.

Subject: Re: [Tutor] Objects, persistence & getting From: "Alan Gauld" <[EMAIL PROTECTED]> Date: Mon, 17 Jan 2005 07:48:28 - To: "Liam Clarke" <[EMAIL PROTECTED]>, "Tutor Tutor" To: "Liam Clarke" <[EMAIL PROTECTED]>, "Tutor Tutor" Well, one thing learning Java is good for is for thoroughly demystifying OOP. I'd have to disagree here because Java's version of OOP has very little to do with real OOP. Java just uss classes as a kind of modularisation mechanism and does not make much use of tthe real OO features. In fact it doesn't even support several of the things that enable real OO programming. And its class library, a strong feature because it is a standard, is dreadful from an OOP p[erspective. In fact I usually refer to Java as a Class Oriented Programming rather than Object Oriented. It is possible to use Java in an OOP way (read Brice Eckel's "Thinking in Java" to see how) but the language itself encourages a style of programming that is much more like Pythons modules than true OOP. It's not some magical acronym of programming goodness, it's just an 'organic' way to organise code. Certainly in Java thats true, and indeed even at the higher level OOP is a way of organizing code - by finding high level abstractions and building tree structures based on common intefaces. But Java doesn't encourage that structuring as much as Python does! Alan G. I've been reading The Object Oriented Thought Process, and it's been clearing up the OOP mystery for me. After reading a big chunk of it, I re-read the OOP sections in Learning Python. It's making a lot more sense now.

Re: [Tutor] Objects & Classes...
I was thinking (it's been a while since I played) that I would do it
like this. (strawman code)
class Character:
def __init__(self,name,attribs,skills,cyberware):
...initialize..
and code to check attrib and skill mins and maxes
physical and menatl attributes should be part of the character
(why would an attri bute need to be a separate class?)
def addCyberware(self...):
def removeCyberware(...):
etc et al.
class Troll(Character):
update min max code in class for each race
class Skill:
def __init__(self, stuff):
perhaps have a subclass for each skill?
in addition the class would be responsible for it's
presentation
class Cyberware:
set attributes skill atribute mods and sanity or what ever thne
subclass for each item. Also taking care of presentation
class Spell:
just like cyberware but perhaps one level further abstraction
class Augment(Spell):
class Damage(Spell):
class Curse(Spell):
I guess the question is should the character class be a *is a* or
*has
a* relationship with Race. Perhaps they could be mixins.
For persistence the only reasonable solution would be an object
persistence scheme of some sort. Then throw in a Top Down RPG Engine
and life is good.

give up because it's really complicated and I don't have time (other
things to do using the aforementioned programming languages, mostly :D
).
I'm probably gonna end up making a web-based one at some point, using
either mod_python or Ruby on Rails. Gah, so many things to do, and so
little time...
Anyway, my view of the problem was that at least the following should
be classes:
- Character
- Attribute
- Skill (perhaps a subclass: Specialization?)
- Augmentation (with subclasses like Cyberware, Bioware, AdeptPower)
- GearItem
Character would mostly be a container for the other classes, so most
of its attributes would be dictionaries, like:
class Character:
def __init__():
self.attributes = {'Body': Attribute(), 'Quickness': Attribute(),
'Strength': Attribute(), 'Charisma': Attribute(), 'Intelligence':
Attribute(), 'Willpower': Attribute()}
Ah, things would be so much easier if McMackie would release the NSRCG
source code (despite this abomination being written in Visual Basic),
wouldn't they? ;)

If it's only that line that you're extracting, and it's format doesn't change
import re

reObj=re.compile(pattern, IGNORECASE)
jay = os.popen("grep ifconfig_fxp0 /etc/rc.conf").readlines()

Re: [Tutor] Objects & Classes...
Ok, so each character has his name, race, his stats, his skills, and his
gear.
since the name and character is unique there is no need for a class
these things.
hmmm maybe I am conceptualizing this wrong.
would each new character then be a dictonary? Made up of different
elements or would the character be a list? Since each character is
basically just a list of stats... the stats get modified up and down by
race and certain gear... am I conceptulizing this correctly?

Re: [Tutor] Walking a directory
Something like this (not tested!):
import os
for dirpath, dirnames, filenames in os.walk('Aircraft'):
for filename in filenames:
if filename.endswith('-set.xml'):
print filename[:-8]
This is probably a good time to mention Jason Orendorff's wonderful path module, which makes this
even simpler:
import path
for filepath in path.path('Aircraft').walkfiles(pattern='*-set.xml'):
print filepath.name[:-8]

I know your going to need some other stuff.
class NewCharacter(Character):
def __init__(self,stats,*args,**kwds):
super(Character,self).__init__(*args,**kwds)
self.stats=stats
super is a function that calls a specific function from a parent
class.
This way you can still use the previous __init__ code and then extend
it. *args represents a tuple of arguments of unspecified length or
type, **kwds is a dictionary of named arguments, like name='' like
above. That way you capture the keywords needed to pass to the
parent
class so that name race magic is still updated at class
instantiation.
This way you can extend classes. So you *could* subclass Character
as a
Dwarf, a Troll etc so that each class already knows about being a
Dwarf,
eg special abilities skill bonuses and such. If you don't understand
this, that's ok it took me quite a while. However once I got this it
made certain tasks much easier. I could figure out how to do
something,
then never need to think about how it works later in the project.

[Tutor] Objects & Classes...
Hello!
I am writing (or at least attempting) to write a Character generation
utility for Shadowrun in Python of course! After reading about other
attempts to make and RPG dealing with with character generation it looks
like OOP is the best way to go. I have no experiance with OOP and its
kinda throwing me for a loop.
Here is what I mean...
I make a class
class Character:
def __init__(self, name = ' ', race = 'Human', magic = 'None'):
self.name=name
self.race=race
self.magic=magic
Great, now I need some from the user to create the character. This is
what I have.
def createChar(book):
name = raw_input("Enter your character's name. ")
race = int(raw_input("What race? (1: Human, 2: Elf, 3: Ork, 4: Troll,
5: Dwarf,)"))
book[name] = race
What am I doing wrong?
Oh and one other thing I can't load my data. I can create a new file,
but not load it. Here is the code for that...
def loadChar(book):
import os
filename = 'SRchargen.dat'
if os.path.exists(filename):
store = open(filename,'r')
while store:
name = store.readline().strip()
race = store.readline().strip()
book[name] = race
else:
store = open(filename, 'w')
store.close
