With my tongue firmly in cheek, I present the following obfuscated solution: eval("{" + reduce(lambda x,y: y+', '+x, [mo.group(1) for mo in __import__ ('re').finditer(r"('E.*?'\s*:\s*'.*?'),?", str(record))], "") + "}") The above should be a single line. eval(), reduce(), lambda, string concatenation in the least efficient way possible, regexes... could it get any worse than this? -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
