	The most blatent error is this line...

	You are calling urllib.urlretrieve passing it arguments of f and the
string "%g.csv".

	THEN you are doing a string interpolation on the RESULT.

	The line should probably be

	urllib.urlretrieve(f, "%s.csv" % clientname)

to apply the string interpolation first, and pass that as the second
argument (also not the %s for /string/ [which, in Python, tends to accept
any argument and produce a general string from it -- using any other format
specification tends to be for cases where you need to match a particular
format... %4.4x if you want zero-filled hex, for example])
