Let's keep it on the list then; no personal email please.

Then something is wrong with the external method. Use a debugger (pdb,
Wing, Komodo, etc.) or spurious logging (import logger;
logger.getLogger('yourmodule').log) to trace your code.

Use "if not len(mlist):"; comparing the length to str(0) is always
false. "len" returns an integer, not a string, so 0 == '0' will never be
True.

You can also call the external method directly if you encode the
arguments passed to it in the query string. Just open up a python
propmt, import urllib and call urllib.quote on your argument list to
hand-construct a URL.

Moreover, get decent books on Python and on Web programming in general.
