Indeed. I recall some Dan Perl who was advised to change his name to a more
pythonic one, but now I see he misinterpreted the advice.
Am I assimilated or what?

Well, since he signs himself "Steve" too I guess we'll just have to
put up with the ambiguities. Or perhaps, given my (lack of) typing
skill, I should just start signing myself "Stvev"?

Indeed. I defy anyone to be a crappier typist then me.

I like to use 'runtime' or 'runtime_options' to store the results of
command-line options. I wasn't sure about this way of getting Python to
handle global variables when I first tried it but after a little
experience with it I think it works out pretty well. One thing I did
learn though is that it's best to keep these modules simple. Don't make
them import or define classes or functions if you can avoid it. It's
easy to get into a mess of recursive imports if you start doing that.
Just a good newbie tip.
***
if runtime.verbose: print 'Something happened.'

What's this doing *here*? I thought the discussion of the pitfalls of
name rebinding was taking place in the "variable declaration" thread.

Steve,
Yes I agree Never use builtin names.
I know better but missed it somehow.
I apologize for any confusion I may have caused.
Thank you Steve for the correction.

Re: global variables

One way to to this is by using keyword args:
class a:
def __init__(self, arg1, arg2, **kwargs):
#
# Dictionary kwargs will have keyword, value pairs
# that can be used as global space.
#
self.arg1=arg1
self.arg2=arg2
self.__dict__.update(kwargs)
return
class b:
def __init__(self, arg1, arg2, **kwargs):
#
# Dictionary kwargs will have keyword, value pairs
# that can be used as global space.
#
self.__dict__.update(kwargs)
self.a=a(arg1, arg2, **kwargs)
return
class c:
def __init__(self, arg1, arg2, **kwargs):
#
# Dictionary kwargs will have keyword, value pairs
# that can be used as global space.
#
self.__dict__.update(kwargs)
self.b=b(arg1, arg2, **kwargs)
return
globals={'global1':1, 'global2':2, 'global3':3, 'global4':4}
C=c(1, 2, **globals)
you will have global1, global2, global3, and global4 attributs
in all classes. If you don't want the attributes, just access
to the values, delete the self.__dict__.update(kwargs) lines.

Hello, |
What about using a class?
Py> class globalVar:
.... pass
Py> globals = globalVar()
Now you can assign 'variables' to it.
And use it anywhere you need it.
Py> globals.image_height = (255,777)
Py> globals.image_mode = 'RGB'
Py> globals.image_names = ['this.jpg', that.jpg']
etc...
hth,
M.E.Farmer |

Not sensibly, though you can mess around with the __builtin__ namespace |
to make values accessible without qualification.
The usual solution is to maintain a config module that establishes
default settings for configuration variables. Other modules that import
config can access (and change) those values using
config.name = value
and so on. Hope this help.
regards
Steve
