Take the biggest value from array

[dwiga]

I don't understand. What is this base you are getting execute and fetchall from? Is it meant to read the table?

Note that join is the opposite of split, so on line 6, b is just equal to data[0].

Hi,
yes, this is fetch from table.
I am trying to do this,

base.execute("select num from tbl_a where nama=%s",(arg1))
hsl = base.fetchall()
print(hsl)

and it returns

Output:
(('2,3',), ('2',), ('1',))

I just want to make it 2,3,2,1
and then I need the biggest value, in this case it should returns 3..
