So basicly final_qu would be ('1','two','hello','2003-08-14','23:32:07')
However has stated above type(final_qu) return tuple.
If final_qu is already a tuple of strings, and what you need is one string
with each string in the tuple concatenated, then you can do this:
final_qu = ('1','two','hello','2003-08-14','23:32:07')
final_qu_str = ' '.join(final_qu)
final_qu_str
'1 two hello 2003-08-14 23:32:07'
If you can't guarantee that each tuple element is a string, try this:
final_qu_str = ' '.join([str(e) for e in final_qu])
final_qu_str
'1 two hello 2003-08-14 23:32:07'
[str(e) for e in final_qu] creates a list of a strings from the elements
[in
final_qu.

OK. Sorry I didn't quite make myslef clear.
final_qu is a string for pydb. The string should be something link:
INSERT INTO foo VALUES "('1','two','hello','2003-08-14','23:32:07')"
I need the () and each value must be inclosed in '' for the database
interface.
Having just been through this myself, you're playing with fire: what if
one of those strings contains a quote character (single or double)?

Let the database interface do the quoting for you. I don't know what
your table looks like, but I see two possibilities (all code untested):

If your table contains a single column in which you're trying to put
that whole string:

sql = """INSERT INTO foo VALUES (%s)"""
params = (repr( final_qu ),) # "str" may work here, too
pydbcursor.execute( sql, params )

If your table contains five columns, one for each element of that tuple:

sql = """INSERT INTO foo VALUES (""" \
+ ','.join( ['%s'] * len( final_qu ) ) \
+ """)"""
params = final_qu
pydbcursor.execute( sql, params )

HTH,
Heather
