How to get another variable type from sql query

From this query...

self.cur.execute("""SELECT pub FROM "20091229"
                 GROUP BY pub ORDER BY pub""")

I get the following list with tuples back.

>&开发者_运维技巧gt;[(1,), (2,), (3,)]

But I need only a list or a list without decimal points in the tuples. Something like these:

[1, 2, 3]

or

[(1), (2), (3)]

Thanks.

It will be better if you tell us what module do you use to work with db. Also i am not sure but your query can be optimized to something like this 'SELECT DISTINCT pub FROM "20091229" ORDER BY pub'

I know that nobody here likes reduce but it could be also used here:

from operator import add

reduce(lambda res,x: add(res, x), [(1,), (2,), (3,)])

OR in case there could be only list of single item tuples:

from operator import itemgetter
map(itemgetter(0), [(1,), (2,), (3,)])

What about this?

li = [tup[0] for tup in li]

Please note, a tuple get's written like this (1,), because (1) would imply mathematical brackets. Also, it seems you are trying to print a list, consider using a dedicated printing function.
