Hi Tutor:
My question is "how to instantiate a subClass using an instance of its baseClass?"
Details below:
=
class B(object):
''' the baseClass '''
def __init__(self, arg1, arg2):
self.a1=arg1
self.a2=arg2
class C(B):
''' C is subClass of B ''

Hi,
I'm having problems understanding some code I came across:
class Singleton:
__single = None
def __init__( self ):
if Singleton.__single:
raise Singleton.__single
Singleton.__single = self
What does passing self to Singleton.__single do?
--Shuying
I have no particularly strong view on the concept (except that I usually
see the "problem" as a valuable opportunity to introduce a concept
that has far wider reaching consequences than floating point
numbers!).
However I do dislike the name nice() - there is already a nice() in the
os module with

I've been thinking
about a function that was recently proposed at python-dev named 'areclose'.
It is a function that is meant to tell whether two (or possible more) numbers
are close to each other. It is a function similar to one that exists in
Numeric. One such implementation is

Thanks, now I understand and that works perfectly.[EMAIL PROTECTED] wrote: David, in getfiles, the os.getcwd() points the main programs cwd only and so shutil.copy() fails. so changing to name = os.path.join(root,name) helps us get the file in the directory we checked against. def getfi
David,
in getfiles, the os.getcwd() points the main programs cwd only and
so shutil.copy() fails.
so
changing to name = os.path.join(root,name) helps us get the file in the
