Beginner question: Converting Single-Element tuples to list

[Paul McGuire]

Modified version of test program, to handle empty strings -> empty
lists.

import pyparsing as pp
import sys

def test(s):
    results = pp.ZeroOrMore( pp.Word(pp.alphas) ).parseString( s )
    print repr(s),"->",list(results)

print "Python version:", sys.version
print "pyparsing version:", pp.__version__
test("abc def")
test("abc")
test("")

Prints:
Python version: 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit
(Intel)]
pyparsing version: 1.3.1
'abc def' -> ['abc', 'def']
'abc' -> ['abc']
'' -> []
