Summary: Code being copied into shelve and UserDi

Initial Comment:
I've been writing a contacts program that uses a 
UserDict as a direct interface to the record which is 
then placed into a shelve.  When I view the DB file 
created by the shelve module I can see my code in the 
Table.

This is a sample from the very start of the shelve 
file, before the first record.  This apears in the 
begining like this no matter how many times I re-run 
it with varying number of records.

            Test=len(CurKeys)
            Temp=1
            NewList=[]
            for list in CurKeys:
                One=int(list)
                NewList.append(One)
                if Test in NewList:
                    Test=Test+1
                    Temp=Test
            NextID='%s' % Temp
            GetEntry=ThisEntry()
            db[NextID]=GetEntry
            print 'New Entry no.',NextID
            db.close()
        
print 'Doneџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџ
џџџџџџџџџџџџџџџџџџџџџџ

This is the method that is actually being looped.  
You'll note at the end the shelve is closed after each 
record is added yet only a single copy of the code.  
I'm baffled as to how this can be?  Not to mention it 
copied the entire document/module without regard to 
scope.

I discovered this when I did a record loop test to 
stuff 1000 records into the shelve.  I opened the file 
to see if there were any noticable problems since I 
don't know what kind of density the shelve can handle 
and saw my code in the table along with the record I 
looped in.

Now I figured I had somehow made the module scope a 
variable that was being looped in with the record so I 
went through the entire 1000 record entries and my 
code only apears once, although it is somewhat broken 
up and much more binary looking than my record.

I'm sure you can understand how much of a problem this 
can be in a comercial app.
