Answer 1

If you are using Python3 you need to open files in text format "wt", more over csv has writerows that can be used to write everything at once. here is an example:

data=[("test", "value1", "value2"), ("test2", "value3", "value4")]
with open('my.csv','wt') as out:
   csv_out=csv.writer(out)
   csv_out.writerows(data)

I've just noticed that the question ask how to transform the list, that is a separate step and here is how I would do it:

lol = [[1,2,3],[4,5,6]]
data = zip(lol[0],lol[1])
