One does not have to declare variables. Very much like REXX. Simply make an assignment.

I don't know anything about Zope (at least I don't think I do.)

I looked up how to capture command line arguments. They are captured by the sys module as a list
using a dedicated variable: argv

# example program from "Processing XML with Python" page 165
# import the sys module
import sys

print "There are", len(sys.argv), 'command-line parameter(s)'
# side note: " and ' are Ok if used in pairs

# print the list
print sys.argv

Here is a sample of a run
C> python args.py a.txt b.txt

There are 3 command-line parameter(s)
['args.py', 'a.txt', 'b.txt']

You can now use Python's list operations to do whatever you want with the parameters.
