Sounds like you want the first element of the tuple which you can
access either as "row[0]" or by unpacking the tuple into a
one-element tuple. The first would look something like
cursor.execute(...)
s = ",".join(rec[0] for rec in cursor.fetchall())
while the second would look something like
cursor.execute(...)
s = ",".join(tablename for (tablename,) in cursor.fetchall())
Note that I'm directly building the string with .join rather than
appending (the growth of which has bad performance in Python).
