python tuple to list

Question

Possible Duplicate:
python tuple to str

Here is the data from the database, I ran out.

>>> policy_id = ((2309L,), (118L,), (94L,))
>>> for i in policy_id:
        print i


(2309L,)
(118L,)
(94L,)

But I want the result as:

i[0]=2309
i[1]=118
i[2]=94

mysql:

 and p.policy_id in ('%s','%s','%s') %(i[0],i[1],i[2])

I also recommend you to read the [Python tutorial](http://docs.python.org/tutorial/). How to access tuples and lists is basic knowledge. — Felix Kling, May 11 '12 at 10:59

You were close. I believe this will do what you want:

p.policy_id = ((2309L,), (118L,), (94L,))

for i in p.policy_id:
    print i[0]

yields:

2309
118
94

If what you want is to have the result in a variable rather than just printing it, you could use a list comprehension:

>>> policy_id_list = [ item[0] for item in policy_id ]
>>> for i in policy_id_list:
...     print i
... 
2309
118
94
