[Zope] Traversal Issue (brain fart)

[Richard Shebora]

Paul and All,

Thanks for the reply.  I see your point about the error trapping.  I 
just got started in Python because it all seems more elegant than the 
DTML I am used to.  The indents were just cut and paste problems.

It seems I am not that far off the target.  I do know the difference 
between a variable name and the value it represents, but I tried many 
ways to represent the following example in a loop that assigned the 
values to "folder1" and so on and have failed.  I don't know the syntax 
to get it done and over the past two weeks have not found it.  I have 
noticed that many times the answer is out there, but I just don't know 
the right keywords to find it.  I have often found the answer to a 
different question when searching for something.

Fixed paths to create the folders...  This make sense to me.
=======================================================
container.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder1, 
'Folder 1','')
container.folder1.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder2, 
'Folder 2','')
container.folder1.folder2.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder3, 
'Folder 3','')
container.folder1.folder2.folder3.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder4, 
'Folder 4','')
container.folder1.folder2.folder3.folder4.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder5, 
'Folder 5','')
print 'Done'
return printed

Variable paths to create the folders...  This is where I get confused 
about the syntax.
The first two are created fine.  I get a key error on the third level.
Which means I am using the variables incorrectly.  But how?
=======================================================
folder1='folder01'
folder2='folder02'
folder3='folder03'
folder4='folder04'
folder5='folder05'
container.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder1, 
folder1,'')
folder=container[folder1]
folder.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder2, 
folder2,'')
folder=container[folder2]
folder.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder3, 
folder3,'')
folder=container[folder3]
folder.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder4, 
folder4,'')
folder=container[folder4]
folder.manage_addProduct['PropertyFolder'].manage_addPropertyFolder(folder5, 
folder5,'')
print 'Done'
return printed

Any clarity on this specific issue would make my day.

Thanks,
Richard
